RK3588 Custom Core Board SDK, WF-C3588-R5, AndroidSBC, San Francisco
TL;DR: RK3588 Custom Core Board SDK
SHENZHEN, China, September 12, 2026 - The WF-C3588-R5 board line at Wanlin Longgang closed lot 209 this week. 38,060 units are now booked for San Francisco, United States, shipped FOB with the full certification file attached.
AndroidSBC head-to-head comparison of the custom RK3588 motherboard platform serving San Francisco, United States. The line spans custom Android motherboards at the entry variant through core-board-plus-carrier work at the SOM end, all on the same Rockchip RK3588 silicon with 6 TOPS NPU, 8K H.265 decode and up to 32GB of LPDDR5. AndroidSBC ships the full range from the Wanlin Longgang plant, and San Francisco buyers can mix custom variants inside a single framework agreement rather than opening a new supplier file for each product line.

About AndroidSBC and the Rockchip RK3588 Board Family
AndroidSBC is the export brand of Wanlin Manufacturing Group. The group runs SMT, test and packing under one roof at Longgang in Shenzhen, and it has built custom boards on Rockchip silicon for overseas OEM customers for over ten years. The WF-C3588 line-up covers nine custom categories on the same Rockchip RK3588 octa-core 8nm silicon with 6 TOPS NPU: custom Android motherboards, custom industrial boards, core board and SOM carrier design, 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. Buyers in San Francisco and United States can source any of the nine custom variants from one factory with one set of export documents.

All parameters in the table above are measured at 25C ambient. The AndroidSBC WF-C3588-R5 (Custom Robotics and AGV Control 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 United States importers sourcing the WF-Series, the 8GB + 32GB (WF-C3588-R5-B) variant is the typical configuration for the custom robotics controller programmes use case, with a sustained weekly capacity of 5,000 pcs/wk on the Longgang line.
Challenges in Sourcing Custom Robotics and AGV Control Board for United States Buyers
Buyers in San Francisco who have sourced a custom robotics and agv control board for a few seasons tend to separate two questions: can the factory hold the price, and can it hold the allocation. The second one is harder. The Rockchip RK3588 is allocated at wafer level, and a 38,060-unit order placed against trader stock is the order most likely to slip a quarter without anyone warning the buyer. The second issue is firmware, not hardware. Vendors promise the full certified software stack and then ship a bare AOSP image, and the failure only surfaces at the warehouse when the unit is powered on against the customer's app.
The third exposure is paperwork. Factories that stamp marks without holding the underlying test reports leave the importer to produce a Technical File after the fact, which is exactly when the container is sitting in a bonded yard. The answer AndroidSBC applies is to close the gap at the source. Custom variant assembled on the Longgang line, certified image burned, burn-in record traceable per unit, certification file issued with the lot. The nine WF-C3588 variants span AGV controllers, AMR mainboards, service robots, inspection robots, quadruped platforms, SLAM navigation, robot vision, fleet dispatch terminals, and charging stations and each carries three memory configurations, which keeps most United States requirements on a standard custom SKU rather than a from-scratch run.
Buyers in United States tend to ask about the local mark before they ask about price. In the United States FCC Part 15 authorisation is required and an FCC ID applies to radio modules, while UL or ETL listing is usually demanded by the retail channel. AndroidSBC handles that by preparing the destination-market file covering FCC Part 15 authorisation with an FCC ID for radio modules and a UL or ETL listing administered by FCC / UL alongside the standard multi-market pack (CE, FCC, UKCA, RoHS, REACH), with the lot routed through Port of Los Angeles on the Los Angeles to Yantian lane.
Competitive Comparison: WF-C3588-R5 vs Competing RK3588 Boards
Competing boards in the custom robotics and agv control board category sort into three camps: cheap catalogue boards with no customization, re-badge imports with a sticker but no engineering file, and source-factory custom boards with the BSP, the certification and the test bench in one building. The WF-C3588-R5 is in the last camp, and its edge is Rockchip RK3588 plus a factory that will route the I/O the project actually needs.
- vs paired PC-plus-MCU controllers: the WF-C3588-R5 runs vision, navigation and fleet logic on one board and hands only the power stage to the drive electronics.
- vs generic SBC robot builds: the CAN, multi-serial and real-time options come validated on the reference carrier instead of being patched in by the integrator.
- vs cloud-vision robots: SLAM and obstacle detection stay on the 6 TOPS NPU, so the robot keeps navigating when the warehouse WiFi drops.
- vs module resellers: custom I/O changes are executed by the Longgang engineering desk with the test bench that will validate them.
Global Custom Robotics Control Board Market Trends
The Custom Robotics Control Board curve is what United States importers read before committing to a custom robotics and agv control board programme. The number they quote is 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, Edge AI Hardware Market Report, 2025-2030), which serves as the closest public proxy for the silicon demand behind custom RK3588 boards. For San Francisco that resolves into three demand patterns across the WF-C3588 order book:
- Warehouse AGV fleet: an automation vendor runs SLAM and fleet dispatch on the board with dual GbE back to the coordinator.
- Display and signage refresh cycles: a longer content loop and a higher panel resolution now define the refresh trigger. The WF-C3588-R5 board carries that headroom without a board change.
- Inspection quadruped: a platform maker runs gait control and inspection vision on isolated cores under PREEMPT_RT.
Channel research on the Custom Robotics Control Board segment keeps landing on the same point: the constraint is allocation, and allocation is held by factories rather than traders.
Across those three segments, San Francisco 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.

Field Report: an engineering review at the Wanlin Longgang plant, where the San Francisco buyer team walked the WF-C3588-R5 carrier design through schematic and stack-up sign-off
Reporter Jiang Bo, on the ground in San Francisco, United States. The buyer's hardware lead spent three days at Longgang reviewing the schematic, the stack-up, and the signal integrity report with the Wanlin engineering desk. Two net-class changes came out of the review and were folded into the next carrier revision before the tooling release.
The engineering desk ran a firmware re-flash drill on three units to confirm the recovery path a field technician would use.
The inspection confirmed three things on the spot: the WF-C3588-R5 units hold the burn-in with a yield above 99.18 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 FCC Part 15 authorisation with an FCC ID for radio modules and a UL or ETL listing administered by FCC / UL, cleared for entry at Port of Los Angeles on the Los Angeles to Yantian 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 United States importers can hand straight to their customs broker.

WF-C3588-R5 Application Scenarios
The WF-C3588 line fits nine custom motherboard lanes, with the WF-C3588-R5 (Custom Robotics and AGV Control Board) as the lead SKU for San Francisco and United States programmes:
- Warehouse AGV fleet: an automation vendor runs SLAM and fleet dispatch on the board with dual GbE back to the coordinator.
- AMR delivery robot: a service robot pairs NPU navigation with a custom carrier that routes the sensor stack.
- Inspection quadruped: a platform maker runs gait control and inspection vision on isolated cores under PREEMPT_RT.
- Cleaning robot fleet: a facility operator runs coverage planning and obstacle detection locally with nightly model updates.
- Charging station control: the board coordinates dock sequencing, battery telemetry and fleet handshakes.
- Agriculture robot: a field robot runs row detection on the NPU offline, kilometres from the nearest access point.
- Remote monitoring link: a fleet operator streams diagnostics over the optional 5G seat to a central depot.
- Robot vision retrofit: an older fleet gains NPU vision without replacing the drive electronics.
Partnership Models for San Francisco Buyers
AndroidSBC opens the WF-C3588 to United States partners through three structures, and a single agreement can draw on more than one:
- 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.
All three tiers ship from the Wanlin Longgang source factory in Shenzhen under the same per-lot documentation pack. For San Francisco buyers, a typical first order on the WF-C3588-R5 is the 8GB + 32GB (WF-C3588-R5-B) configuration at MOQ 5,000 units per shipment, with standard-variant samples in 1-3 days and 15-30 days to mass production on custom runs.
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 United States 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: Yes. Under NDA, AndroidSBC delivers custom Android ROM work with proprietary services and a locked launcher, custom Linux images on Ubuntu, Debian, Yocto or Buildroot, BSP ports for customer carriers, and driver development for project-specific I/O. Source access is released to the partner, and the port is performed at Longgang, which matters because a vendor BSP rarely matches a custom carrier revision on the first try.
Can the 6 TOPS NPU on a custom board run our own AI models?
Answer: The NPU is fully open on the custom line. Bring the model in PyTorch, ONNX, TensorFlow or Caffe and the Longgang desk handles the RKNN quantization, the runtime integration and the validation against your board's thermal and memory profile. Custom AI algorithm integration is a standard line item on the ODM scope, and the resulting model ships embedded in the firmware image burned per lot.
What are the MOQ and lead times for a custom RK3588 motherboard?
Answer: Standard-variant samples ship in 1-3 days from stock, so your engineering team can start integration while the custom scope is being quoted. A custom run follows a 15-30 day mass-production window after schematic and stack-up sign-off. MOQ is 5,000 units per shipment on standard variants; on custom configurations the MOQ is negotiable against volume commitments, and small batch orders are accepted for pilot phases. A twelve-month framework agreement with monthly lot releases brings the per-lot MOQ down further.
What certifications does a custom board need for United States, and who handles them?
Answer: Yes, and the file travels with the goods. The pack covers CE, FCC Part 15, UKCA, RoHS 2.0, REACH and IEC 62368-1 with the EMC and safety reports for your configuration, dated within the prior year. AndroidSBC confirms any United States-specific addition at quotation stage, which is the point where the answer is still useful rather than expensive.
How long will AndroidSBC keep supplying a custom board?
Answer: The commitment is seven years minimum on supply, with security patches back-ported across the Android and Linux firmware tracks and OTA infrastructure for pushing firmware and RKNN model updates to deployed units. Long-lifecycle programmes in industrial, signage and robotics usually ask for the term in writing, and it is written.
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: AndroidSBC targets a 0.3 percent DOA rate across the WF-C3588 line, measured over the prior twelve months. On RMA, the partner returns the faulty WF-C3588-R5 unit to Longgang with its burn-in barcode, and a replacement ships within ten business days. Because the burn-in record and the configuration file are attached per unit, the failure analysis normally comes back with a root cause rather than a credit note, which matters when a custom configuration is holding up a production line.
