TL;DR: RK3588 Mini-ITX Form Factor

SHENZHEN, China, September 11, 2026 - The WF-RK3588-C4 board cleared the Longgang aging bench this week in lot 460, a 26,895-unit run for Ho Chi Minh City, Vietnam, and moved straight to the container yard.

AndroidSBC factory capacity report for the nine-variant WF-RK3588 line serving Ho Chi Minh City, Vietnam. The WF-RK3588 line is 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 and INT4, INT8, INT16, FP16, BF16 and TF32 support, paired with up to 32GB of LPDDR4X or LPDDR5. AndroidSBC, the export arm of Wanlin Manufacturing Group, ships nine variants off the Longgang source factory in Shenzhen to Ho Chi Minh City and Vietnam: WF-RK3588-E0 edge AI inference box, WF-RK3588-V1 industrial machine vision processor, WF-RK3588-R2 robotics and AGV controller, WF-RK3588-N3 AI NVR with analytics, WF-RK3588-C4 smart cockpit and in-vehicle AI, WF-RK3588-D5 8K digital signage and video wall player, WF-RK3588-K6 self-service kiosk and POS, WF-RK3588-P7 ARM PC and mini-PC, and WF-RK3588-S8 SMARC 2.2 SOM.

About AndroidSBC and the Rockchip RK3588 Board Family

The WF-RK3588 is a nine-variant NPU computing line from AndroidSBC, the export arm of Wanlin Manufacturing Group in Shenzhen. One Rockchip RK3588 silicon, nine application variants: edge AI inference, industrial machine vision, robotics and AMR, AI NVR, smart cockpit, 8K signage, kiosk and POS, ARM PC and mini-PC, plus a SMARC 2.2 SOM. 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 Vietnam importers, the line covers the edge AI, vision, robotics, AI NVR, cockpit, signage, kiosk and ARM PC categories that a Ho Chi Minh City distributor is most often asked to quote.

WF-RK3588-C4 Technical Specifications

All parameters in the table above are measured at 25C ambient. The AndroidSBC WF-RK3588-C4 (Smart Cockpit and In-Vehicle AI) 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 Vietnam importers sourcing the WF-Series, the 8GB + 64GB automotive (WF-RK3588-C4-A) variant is the typical configuration for the smart cockpit, IVI, and in-vehicle AI use case, with a sustained weekly capacity of 5,000 pcs/wk on the Longgang line.

Challenges in Sourcing Smart Cockpit and In-Vehicle AI for Vietnam Buyers

Buyers in Ho Chi Minh City who have run the smart cockpit and in-vehicle ai 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 26,895-unit order can look cheap on paper and expensive in a slipped quarter. Then comes the firmware question. The hardware spec is straightforward to verify; whether the board holds a credential-locked stack through a 72-hour loop and a field OTA is a different test, and it is normally the Ho Chi Minh City buyer's warehouse that discovers the answer.

Documentation closes the list. Buyers in Ho Chi Minh City 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 both risks inside the factory: the certified image is burned at Longgang, the burn-in record is attached per unit barcode, and the Technical File ships with the lot. Across the nine WF-RK3588 variants the coverage runs from smart cockpit, in-vehicle infotainment, AVM surround view, DMS driver monitoring, BSD blind spot detection, rear seat entertainment, digital instrument cluster, fleet management terminal, commercial vehicle telematics, and one-chip seven-screen cockpit, with three memory configurations per variant, so a Ho Chi Minh City buyer can usually match a requirement from standard stock.

Compliance for Vietnam is handled at the factory rather than after arrival. In Vietnam MIC type approval and the CR conformity mark are both required, and the approval is held by a Vietnamese importer. The Longgang export desk builds the destination-market file for MIC type approval with the CR conformity mark administered by MIC Vietnam and issues it alongside the standard multi-market pack (CE, FCC, UKCA, RoHS, REACH), with the shipment booked into Cat Lai Terminal, Ho Chi Minh City on the Cat Lai to Shekou lane.

Competitive Comparison: WF-RK3588-C4 vs Competing RK3588 Boards

The comparison set for the smart cockpit and in-vehicle ai socket splits three ways: Cortex-A53 boards priced low with no NPU, Cortex-A55 boards that carry a 1 to 2 TOPS NPU but cap decode early, and 64-bit octa-core boards with a 6 TOPS NPU and 8K H.265. The WF-RK3588-C4 sits in the third group, differentiated by Rockchip RK3588, by NPU throughput stability under a continuous load, and by the factory-side certified image burn.

• vs RK3568 1 TOPS cockpit boards: the WF-RK3588-C4 triple-core NPU runs DMS plus AVM plus BSD on the same silicon with margin.
• vs x86 cockpit PCs: the WF-RK3588-C4 fanless design holds -40C to 85C without active cooling and the BOM stays under the x86 reference.
• vs single-camera DMS boxes: the WF-RK3588-C4 carries six MIPI CSI plus two AVM cameras plus the DMS IR camera on the same board.
• vs discrete GPU ADAS boxes: the WF-RK3588-C4 integrates the inference engine on-die rather than depending on an external GPU.

Global Smart Cockpit and In-Vehicle AI Market Trends

Order timing in Ho Chi Minh City now tracks the Smart Cockpit and In-Vehicle AI curve rather than the calendar-year budget. MarketsandMarkets sizes the Edge AI hardware segment at USD 26.9 billion for 2025 with a 32.7 percent CAGR through 2030 (MarketsandMarkets, 2025-2030), the AI accelerator silicon baseline that Vietnam buyers keep on the desk when they negotiate allocation. Three patterns are visible in the WF-RK3588 book:

• Smart cockpit: WF-RK3588-C4 drives the cluster plus the centre stack plus the passenger display from one board.
• Display and signage refresh cycles: a longer content loop and a higher panel resolution now define the refresh trigger. The WF-RK3588-C4 board carries that headroom without a board change.
• DMS driver monitoring: WF-RK3588-C4 runs the gaze plus distraction model on the NPU against the IR camera feed.

For the Smart Cockpit and In-Vehicle AI category the practical signal in Vietnam is that framework agreements are replacing spot buying, and the agreements are getting longer.

Taken together, the three patterns explain why Vietnam buyers are moving from single orders to twelve-month framework agreements with a monthly lot cadence, especially on edge AI and machine vision programmes that cannot absorb a supply gap.

- Katrin Vogt, Head of Engineering

Field Report: SMT line No.3 at the Wanlin Longgang plant, with operators loading Rockchip RK3588-based WF-RK3588-C4 boards for the 26,895-unit order bound for Ho Chi Minh City

Reporter Li Jian, on the ground in Ho Chi Minh City, Vietnam. Wanlin Longgang SMT line No.3 put the lot through three AOI passes and an X-ray inspection on every BGA package before it reached the burn-in rack. The WF-RK3588-C4 boards then cleared 48 hours of thermal cycling between -20C and 70C with the decoder loaded against a stress stream. Final yield came in at 99.06 percent.

Pallet weights were checked against the packing list at the dock, and the container was sealed 25 minutes before the cut-off.

The inspection confirmed three things on the spot: the WF-RK3588-C4 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 MIC type approval with the CR conformity mark administered by MIC Vietnam, cleared for entry at Cat Lai Terminal, Ho Chi Minh City on the Cat Lai to Shekou lane. Wanlin remains one of the few source factories currently shipping a nine-variant Rockchip RK3588 NPU computing line with a per-lot paper trail that Vietnam importers can hand straight to their customs broker.

Partnership Models for Ho Chi Minh City Buyers

For Ho Chi Minh City importers and brand owners, the WF-RK3588-C4 and the rest of the WF-RK3588 NPU variants are available 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 tier a Vietnam partner picks, the goods leave Longgang with one documentation pack covering CE, FCC, UKCA, RoHS and IEC 62368-1. The usual first order on the WF-RK3588-C4 is the 8GB + 64GB automotive (WF-RK3588-C4-A) configuration at MOQ 5,000 units, four weeks for samples and six weeks for mass production.

Frequently Asked Questions

Does the WF-RK3588 line run Android or Linux, and what NPU framework stack is supported?

Answer: Yes on both. The WF-RK3588 line ships with Android 12 and Android 13 prebuilt, with Android 14 builds under validation. The Linux side covers Ubuntu 22.04 LTS, Debian 12, Yocto Kirkstone and Buildroot 2023.02, all of which load the Rockchip RKNN-Toolkit2 NPU runtime and the rknn-cross-compiler. That gives a Vietnam integrator the freedom to run the certified Android TV and signage stack on one variant and a Linux NPU inference runtime on another variant from the same silicon, which is unusual for a single source factory.

What is the 6 TOPS triple-core NPU on the WF-RK3588 actually used for in production?

Answer: Three workloads that have already shipped at scale. On the WF-RK3588-E0 the NPU drives retail analytics (people counting, dwell time, demographic classification) at 25fps per stream. On the WF-RK3588-V1 the same silicon runs machine-vision defect classification at line speed on a factory floor. On the WF-RK3588-N3 it carries 16-channel AI surveillance analytics (person, vehicle, behaviour) on a fanless board. Each variant is tuned for its workload, but the silicon is the same, and that is what makes one supplier file cover nine deployment categories for Vietnam buyers.

Can AndroidSBC handle CE, FCC, UKCA, RoHS, REACH and IEC 62368-1 paperwork for Vietnam?

Answer: Yes, and the file travels with the goods rather than behind them. The pack covers CE, FCC Part 15, UKCA, RoHS 2.0, REACH and IEC 62368-1 with test reports dated within the prior year. AndroidSBC will also advise on any Vietnam-specific addition during quotation, which is the point at which the answer is still useful.

What are the MOQ and lead time for a first order on the WF-RK3588?

Answer: The entry point is 5,000 units per shipment, four weeks for samples and six weeks for production. A twelve-month framework agreement released monthly will bring the per-lot MOQ down, and AndroidSBC will accept a mixed order that draws several WF-RK3588 variants against a single contract.

Does AndroidSBC support custom Android ROM, custom Linux, or custom NPU model porting?

Answer: Yes, under NDA. ODM partners get custom Android ROM work including proprietary services and a custom launcher, Linux builds based on Ubuntu, Debian, Yocto or Buildroot, BSP ports for custom carrier boards, and NPU model porting through the Rockchip RKNN-Toolkit2 (quantization from PyTorch, ONNX, TensorFlow, Caffe and MXNet). The SDK and BSP source are released to the partner under the NDA, and AndroidSBC's engineering desk handles the port rather than handing over an unmodified vendor drop.

What about software updates and long-term support on the WF-RK3588?

Answer: Seven years minimum supply, with security patches maintained across the Android, Ubuntu LTS and Yocto firmware lines. Partners who deploy at scale can use the AndroidSBC OTA infrastructure to update field units and push new RKNN NPU model builds. For long-lifecycle programmes in machine vision, AI NVR, robotics or industrial control, the support term is written into the framework agreement at signature.

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

Answer: That is routine. AndroidSBC delivers DDP into Amazon FBA in the US, EU and Japan and into 3PL consolidation points at Hong Kong, Singapore, Rotterdam, Los Angeles and Shenzhen. Carton and pallet configuration follows FBA inbound rules, and the place of origin on the declaration is the Wanlin Longgang source factory.

How does AndroidSBC handle RMA or DOA replacements on the WF-RK3588?

Answer: The DOA target is 0.3 percent over twelve months. For RMA, partners send the WF-RK3588-C4 unit back to Longgang with the burn-in barcode attached, and replacements go out within ten business days. The per-unit burn-in record means the failure report usually carries a root cause alongside the replacement, which is what a Vietnam integrator running a production line actually needs.
