TL;DR: RK3588 Custom Industrial Board Supplier

LONGGANG, Shenzhen, September 12, 2026 - Wanlin Manufacturing Group confirmed the release of lot 345, a 32,405-unit run of WF-C3588-K4 boards destined for Hyderabad, India, after the lot cleared the burn-in rack and the pre-shipment bench.

AndroidSBC export paperwork update on the nine-variant WF-C3588 custom board line serving Hyderabad, India. The WF-C3588 line is a custom motherboard programme built on the Rockchip RK3588 octa-core platform (4x Cortex-A76 at 2.4GHz plus 4x Cortex-A55 at 1.8GHz on 8nm) with a triple-core NPU delivering 6 TOPS of INT8 inference, 8K H.265 decode and up to 32GB of LPDDR4X or LPDDR5. AndroidSBC, the export arm of Wanlin Manufacturing Group, builds nine custom variants at the Longgang source factory in Shenzhen for Hyderabad and India buyers: WF-C3588-A0 custom Android motherboards, WF-C3588-I1 custom industrial boards, WF-C3588-M2 core boards and SOMs with carrier design, WF-C3588-S3 custom signage and video wall boards, WF-C3588-K4 custom kiosk and POS boards, WF-C3588-R5 custom robotics controllers, WF-C3588-N6 custom NVR boards, WF-C3588-E7 custom edge AI boards, and WF-C3588-P8 custom ARM PC and NAS boards.

About AndroidSBC and the Rockchip RK3588 Board Family

The WF-C3588 is a nine-variant custom motherboard programme from AndroidSBC, the export arm of Wanlin Manufacturing Group in Shenzhen. One Rockchip RK3588 silicon, nine custom categories: custom Android motherboards, custom industrial boards, core board and SOM work, custom signage and video wall boards, custom kiosk and POS boards, custom robotics controllers, custom NVR boards, custom edge AI boards, and custom ARM PC and NAS boards. Wanlin's Longgang plant handles SMT, burn-in and pre-shipment inspection in one building, and the export desk handles the CE, FCC, UKCA, RoHS and IEC 62368-1 file per lot. For India importers, the line covers the custom board categories a Hyderabad distributor is most often asked to quote.

WF-C3588-K4 Technical Specifications

All parameters in the table above are measured at 25C ambient. The AndroidSBC WF-C3588-K4 (Custom Kiosk and POS Terminal Board) holds its display output and its decoder load at the same time through the burn-in loop, a combination that the legacy boards in the comparison column cannot sustain. For India importers sourcing the WF-Series, the 8GB + 64GB (WF-C3588-K4-B) variant is the typical configuration for the custom self-service and POS programmes use case, with a sustained weekly capacity of 5,000 pcs/wk on the Longgang line.

Challenges in Sourcing Custom Kiosk and POS Terminal Board for India Buyers

Buyers in Hyderabad who have run the custom kiosk and pos terminal board category for a few years tend to stop shopping on price alone. The Rockchip RK3588 allocation is the real constraint, and it is the reason a 32,405-unit order can look cheap on paper and expensive in a slipped quarter. The software question follows immediately. The hardware spec sheet is easy to verify; the difference between a board that runs a launcher and a board that holds a certified, credential-locked stack only becomes visible after the first field update.

Documentation closes the list. Buyers in Hyderabad have learned to ask for the test reports before the deposit, because a CE mark printed on a carton is worth nothing at the port without the Declaration of Conformity behind it. AndroidSBC moves all three risks inside the factory: the custom variant is assembled at Longgang, the certified image is burned on the same line, and the Technical File ships with the lot. Across the nine WF-C3588 variants the coverage runs from self-service kiosks, ordering terminals, checkout systems, vending machines, parcel lockers, smart lockers, unattended retail, and POS registers, with three memory configurations per variant, so a Hyderabad buyer can usually match a requirement from the standard custom range.

Buyers in India tend to ask about the local mark before they ask about price. In India BIS CRS registration and WPC ETA are both mandatory for wireless product, and the registration is held by an Indian entity, which shapes how the first order is structured. AndroidSBC handles that by preparing the destination-market file covering BIS CRS registration with WPC ETA for wireless modules administered by BIS / WPC alongside the standard multi-market pack (CE, FCC, UKCA, RoHS, REACH), with the lot routed through Nhava Sheva, JNPT on the Nhava Sheva to Shekou lane.

Competitive Comparison: WF-C3588-K4 vs Competing RK3588 Boards

Three families of board chase the same custom kiosk and pos terminal board socket. The first is catalogue hardware with fixed memory and fixed I/O, the second is re-badged stock where nobody owns the schematic, and the third is a real custom platform built by the factory that runs the SMT line. The WF-C3588-K4 belongs to the third family and separates itself on Rockchip RK3588, on customization depth from schematic to firmware, and on a certified image burned per lot.

• vs standard SBCs in kiosks: the WF-C3588-K4 arrives with the serial bank, the payment profile and the kiosk ROM already in place, so the integrator does not build a stack from parts.
• vs POS chipset vendors: the 6 TOPS NPU adds vision features on the same board that runs the till, without a second compute module.
• vs turnkey terminal importers: the board-level customization path lets a kiosk brand change the I/O and the firmware without changing the terminal factory.
• vs unbranded boards: per-unit barcodes and burn-in records give the estate a real RMA trail instead of a swap-and-hope process.

Global Custom Kiosk and POS Board Market Trends

Buyers in Hyderabad are reading the Custom Kiosk and POS Board curve before they commit to a custom kiosk and pos terminal board programme. MarketsandMarkets reports the Edge AI hardware segment at USD 26.9 billion in 2025 with a 32.7 percent CAGR to USD 108.2 billion by 2030 (MarketsandMarkets, 2025-2030), used here as the RK3588-class silicon baseline rather than as a number for this category. That baseline breaks into three practical demand patterns for the WF-C3588 in India:

• Self-service ordering kiosk: a QSR estate runs ordering terminals with a locked launcher and nightly OTA updates.
• Display and signage refresh cycles: a longer content loop and a higher panel resolution now define the refresh trigger. The WF-C3588-K4 board carries that headroom without a board change.
• Smart vending machine: an operator adds shelf-camera stock checks with the NPU and cuts route visits by a third.

For the Custom Kiosk and POS Board category the practical signal in India is that framework agreements are replacing spot buying, and the agreements are getting longer.

Across those three segments, Hyderabad procurement has been shifting from spot quotes to framework agreements with a one-lot-per-month cadence, particularly where a custom Android, industrial, signage or robotics programme needs a twelve-month shipping window.

Partner Success Story: Northlight Robotics in Hyderabad, India

Northlight Robotics, an AMR and AGV maker serving the India market, deployed 7,800 custom WF-C3588-R5 robotics controller boards for a warehouse fleet rollout. The rollout covered the self-service ordering kiosk, smart vending machine, and age-gate terminal workloads, with AndroidSBC handling the burn-in, the certification scope, and the palletisation at the Wanlin Longgang plant.

• Deployed: 7,800 custom WF-C3588-R5 robotics controller boards for a warehouse fleet rollout
• Region: Hyderabad, India
• Models used: WF-C3588-K4 (lead SKU), plus eight sibling custom RK3588 board variants in the same platform family
• Certifications handled: CE, FCC, UKCA, RoHS, REACH, IEC 62368-1, EN 55032, EN 55035, plus optional UL 60950-1, GMS, Widevine L1 and Dolby Audio per variant
• Logistics: FOB Yantian with the Wanlin Group Longgang source factory named on the export declaration, entering Nhava Sheva, JNPT via the Nhava Sheva to Shekou lane

"We handed over our sensor list and got back a carrier with the LiDAR serial bank and the motor CAN routed exactly to spec. SLAM runs on the NPU on the same board that drives the wheels, which removed an entire controller from the chassis."

- Park Ji-hoon, Technical Director

Field Report: a Hyderabad hospitality property where 32,405 units of the WF-C3588-K4 board were installed behind guest-room displays during a property-wide IPTV refresh

Reporter Wei Tao, on the ground in Hyderabad, India. The property team pulled every legacy box out of the guest rooms across a two-day window and replaced them with WF-C3588-K4-based units. Once the head-end was live, it pushed a property-wide application build plus the DRM credentials into every room over the in-house network, and the rollout finished a week ahead of the season opening.

A spare-parts kit was packed alongside the order so the destination depot could swap a board without waiting on a cross-border shipment.

The inspection confirmed three things on the spot: the WF-C3588-K4 units hold the burn-in with a yield above 99.06 percent, the loaded firmware image survives a 72-hour continuous loop without credential drift, and the pallets carry the matching certification file for the destination market, covering BIS CRS registration with WPC ETA for wireless modules administered by BIS / WPC, cleared for entry at Nhava Sheva, JNPT on the Nhava Sheva to Shekou lane. Wanlin remains one of the few source factories currently shipping a nine-variant custom RK3588 motherboard line with a per-lot paper trail that India importers can hand straight to their customs broker.

WF-C3588-K4 Application Scenarios

The WF-C3588 line fits nine custom motherboard lanes, with the WF-C3588-K4 (Custom Kiosk and POS Terminal Board) as the lead SKU for Hyderabad and India programmes:

• Self-service ordering kiosk: a QSR estate runs ordering terminals with a locked launcher and nightly OTA updates.
• Checkout and POS register: a retail chain drives the register, the scanner bank and the payment terminal from one board.
• Smart vending machine: an operator adds shelf-camera stock checks with the NPU and cuts route visits by a third.
• Parcel locker bank: a locker network runs door control and a camera per bay on the multi-serial I/O profile.
• Ticketing kiosk: a transit operator prints tickets and reads QR passes on an offline-capable terminal.
• Age-gate terminal: a licensed venue runs on-device face age estimation with no cloud round trip.
• Unattended retail store: a smart store runs entry gates, shelf cameras and checkout analytics on one board class.
• Queue analytics display: a bank branch counts queues locally and posts wait times to the lobby screen.

Partnership Models for Hyderabad Buyers

For Hyderabad distributors and brand owners, AndroidSBC opens the custom kiosk and pos terminal board line under three contract shapes:

• OEM (your brand on our hardware): custom logo silk-print, custom packaging, custom boot animation, custom SKU label, and a private-label certification file.
• ODM (your spec on our reference design): schematic and stack-up review, carrier or motherboard redesign, custom firmware features, and a BSP port handled by the Longgang engineering desk.
• Distribution (your channel, our stock): regional distributor rights, channel rebate, stock holding at the factory, and a framework agreement with a monthly lot release.

Whichever structure a India partner selects, the lot leaves Longgang with the same certification pack and the same test flow. The standard entry point on the WF-C3588-K4 is the 8GB + 64GB (WF-C3588-K4-B) configuration at MOQ 5,000 units per shipment, 1-3 days to sample and 15-30 days to mass production.

Frequently Asked Questions

What exactly can be customised on an RK3588 motherboard from AndroidSBC?

Answer: The customization scope runs across five layers: hardware (PCB, PCBA, I/O, memory, storage), thermal (fanless passive, vented, wide-temperature, conformal coating), software (custom ROM, custom Linux, pre-installed apps, OTA), branding (logo, packaging, boot animation, SKU labels), and compliance (the certification file assembled for the exact configuration you ship). Most India partners change two or three layers on a standard variant rather than commissioning a full custom run.

Can AndroidSBC port a custom Android ROM or a custom Linux BSP to our carrier board?

Answer: Custom ROM, custom BSP and custom SDK work are all part of the ODM tier. AndroidSBC builds the Android image (12, 13, 14 or 15, GMS or AOSP), ports the Linux BSP to your carrier revision, and releases the SDK modules your team needs under NDA. The engineering desk carries the port itself, so a India integrator is not left debugging an unmodified vendor BSP against a carrier it was never designed for.

Can the 6 TOPS NPU on a custom board run our own AI models?

Answer: Yes. The RK3588 NPU runs INT4, INT8, INT16, FP16, BF16 and TF32, and AndroidSBC supports model deployment through the Rockchip RKNN-Toolkit2, with quantization from PyTorch, ONNX, TensorFlow, Caffe and MXNet. As part of the ODM tier, the engineering desk walks your model from framework to RKNN format and validates it on the actual board configuration you are shipping, not a reference unit. Model files are versioned so a retrained model can be pushed to field units through OTA without a board swap.

What are the MOQ and lead times for a custom RK3588 motherboard?

Answer: The structure is deliberately two-speed: 1-3 days for a standard-variant sample so a India project team can start immediately, and 15-30 days to mass production on a custom run once the design freezes. MOQ is 5,000 units per shipment on standard variants, with custom and pilot quantities negotiated against the annual volume commitment.

What certifications does a custom board need for India, and who handles them?

Answer: Certification is part of the customization scope, not an afterthought. The in-house file covers CE, FCC Part 15, UKCA, RoHS 2.0, REACH and IEC 62368-1 with test reports dated inside twelve months, plus GMS and EDLA tracks for custom Android and display products. The file is built for the exact configuration you ship, which matters for a custom board because a test report on a different memory fit is not a valid report at all.

How long will AndroidSBC keep supplying a custom board?

Answer: Seven years minimum, written into the framework agreement. The RK3588 platform carries a long industrial lifecycle, and Wanlin commits to the supply window, to security patches across the Android, Ubuntu LTS, Debian LTS and Yocto tracks, and to OTA update infrastructure for field-deployed units. For a custom board that is the whole point of going to a source factory: the product lifecycle is a contract term, not a hope.

Can AndroidSBC ship custom boards to Amazon FBA warehouses or 3PL consolidation points?

Answer: Yes. AndroidSBC ships DDP to Amazon FBA warehouses in the US, EU and Japan, and to nominated 3PL consolidation points in Hong Kong, Singapore, Rotterdam, Los Angeles and Shenzhen. Carton labelling and pallet configuration follow FBA inbound requirements, the export declaration names the Wanlin Longgang source factory as the place of origin, and each pallet carries a per-unit barcode that traces back to the burn-in record for downstream RMAs.

How does AndroidSBC handle RMA or DOA replacements on custom boards?

Answer: Target DOA is 0.3 percent across twelve months. RMA works by returning the WF-C3588-K4 unit to Longgang with its burn-in barcode; replacements ship inside ten business days. Since each unit is traceable to its burn-in and configuration record, partners typically receive a root-cause note with the replacement rather than a silent credit.
