Self-service Printing Kiosk Board, WF-RK3588S, AndroidSBC, Charlotte

TL;DR: Self-service Printing Kiosk Board

SHENZHEN, China, September 10, 2026 - Wanlin Manufacturing Group pushed lot 374 of the WF-RK3588S board out of the Longgang plant this week, 30,520 units for Charlotte, United States, with the export declaration naming Longgang as the place of origin.

AndroidSBC capacity disclosure from the Longgang custom board lines serving Charlotte, United States. AndroidSBC is opening the full WF-Series to United States: Allwinner A133, H618, and T527 on one side, Rockchip RK3588, RK3568, RK3566, and RK3288 on the other, plus WF-A133S and WF-RK3588S for carrier-board work. Every board ships from the Wanlin Longgang facility with OEM branding available, ODM carrier design handled in-house, and per-lot CE, FCC, UKCA, and RoHS documentation.

About AndroidSBC and the Rockchip RK3588 Board Family

Wanlin Manufacturing Group is a Shenzhen board builder that has worked on Allwinner and Rockchip silicon for more than ten years, and AndroidSBC is the name it sells under overseas. The WF-Series is the current line: nine boards spanning Allwinner A133, H618, and T527 and Rockchip RK3588, RK3568, RK3566, and RK3288, with two SOM modules for customers who bring their own carrier. Production, test, and packing sit in one Longgang building, which is why the group can issue a per-lot Technical File instead of a generic declaration. Buyers in Charlotte and United States usually arrive for one of three reasons: platform breadth, OEM branding capacity, or a supplier willing to carry the certification obligation.

WF-RK3588S Technical Specifications

All parameters in the table above are measured at 25C ambient. The AndroidSBC WF-RK3588S (SOM Module and SMARC Carrier 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 + 64GB, SMARC 2.2 (WF-RK3588S-A) variant is the typical configuration for the SMARC module and custom carrier integration use case, with a sustained weekly capacity of 5,000 pcs/wk on the Longgang line.

Challenges in Sourcing SOM Module and SMARC Carrier Board for United States Buyers

The first thing United States procurement teams learn about the som module and smarc carrier board category is that quotation speed and delivery reliability are inversely related. The Rockchip RK3588 needs a wafer slot that a broker cannot create, so the fastest quotes are often the ones attached to the least secure allocation. Then there is the software build. A board that boots is not the same as a board that carries the certified stack a United States retailer will accept, and the gap is normally found during inbound QC rather than at the factory gate.

Then there is the certification file. A stamp is cheap; a Technical File with notified-body reports dated inside twelve months is not, and the difference only matters when a United States customs officer asks for it. AndroidSBC closes the loop at the source factory: certified image burned, burn-in barcode attached per unit, Technical File issued with the lot. The nine WF-Series models cover SMARC module design, COM Express Type 6 builds, edge AI boxes, video wall controllers, medical imaging terminals, autonomous vehicle compute, and bespoke industrial carriers and each ships in three memory configurations, so most Charlotte requirements can be met from standard stock rather than a custom production run.

For United States specifically, the file travels with the goods. 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 prepares the FCC Part 15 authorisation with an FCC ID for radio modules and a UL or ETL listing documentation for FCC / UL, attaches the standard multi-market pack (CE, FCC, UKCA, RoHS, REACH), and consigns the lot to Port of Los Angeles on the Los Angeles to Yantian lane.

Competitive Comparison: WF-RK3588S vs Competing RK3588 Boards

Three families of board chase the same som module and smarc carrier board socket. The first is legacy silicon at a low price with no software certification, the second is Cortex-A55 hardware with certification but limited decode headroom, and the third carries both yet treats expansion as an afterthought. The WF-RK3588S belongs to the third family and separates itself on Rockchip RK3588, sustained display output under load, and a certified image burned per lot.

• vs proprietary SOM pin-outs: the SMARC 2.2 standard lets the carrier survive a module generation change without a re-layout.
• vs RK3568 SMARC modules: the RK3588 module adds 8K@60fps decode, PCIe 3.0 x4, and 6 TOPS NPU on the same 314-pin edge.
• vs x86 COM Express modules: the RK3588 module runs Android natively, which removes the OS licensing line from the BOM.
• vs module-only vendors: AndroidSBC ships the carrier reference design plus the signal integrity report with the module.

Global SMARC and COM Express Module Engineering Market Trends

Buyers in Charlotte are reading the SMARC and COM Express Module Engineering curve before they commit to an som module and smarc carrier board programme. Global Growth Insights reports the Android TV Box segment at USD 12.45 billion in 2025 with a 30.49 percent CAGR to USD 178.2 billion by 2035 (Global Growth Insights, 2025-2035), used here as the Android silicon demand baseline rather than as a number for this category. That baseline breaks into three practical demand patterns for the WF-Series in United States:

• SMARC module design: WF-RK3588S seats on the 314-pin MXM edge with the carrier holding the I/O.
• Display and signage refresh cycles: a longer content loop and a higher panel resolution now define the refresh trigger. The WF-RK3588S board carries that headroom without a board change.
• Edge AI boxes: WF-RK3588S runs 6 TOPS NPU inference on the carrier-side thermal solution.

The SMARC and COM Express Module Engineering commentary has shifted from unit growth to supply reliability, and that shift favours suppliers who control their own SMT and burn-in lines.

The common thread in United States is that single orders are being replaced by blanket agreements with a monthly release, because a programme that has to survive a twelve-month window cannot absorb an allocation gap in the middle of it.

Partner Success Story: Lumen Menu Systems in Charlotte, United States

Lumen Menu Systems, a quick-service restaurant technology vendor serving the United States market, deployed 6,900 units of the WF-A133 board for outdoor menu and order confirmation displays. The rollout covered the smarc module design, edge ai boxes, and autonomous vehicle compute workloads, with AndroidSBC handling the burn-in, the certification scope, and the palletisation at the Wanlin Longgang plant.

• Deployed: 6,900 units of the WF-A133 board for outdoor menu and order confirmation displays
• Region: Charlotte, United States
• Models used: WF-A133, WF-H618, WF-T527, WF-RK3588, WF-RK3568, WF-RK3566, WF-RK3288, WF-A133S, WF-RK3588S

"Outdoor menu boards have to survive sun and rain. The A133 board runs the content loop behind a sealed panel with no active cooling, and we have not replaced a single unit in eighteen months."

- Priya Raghavan, VP Hardware

Field Report: a Charlotte hospitality property where 30,520 units of the WF-RK3588S board were installed behind guest-room displays during a property-wide IPTV refresh

Reporter Lu Kang, on the ground in Charlotte, United States. The property team pulled every legacy box out of the guest rooms across a two-day window and replaced them with WF-RK3588S-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.

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-RK3588S units hold the burn-in with a yield above 99.27 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-board Allwinner and Rockchip custom line with a per-lot paper trail that United States importers can hand straight to their customs broker.

WF-RK3588S Application Scenarios

The WF-Series fits nine application lanes, with the WF-RK3588S (SOM Module and SMARC Carrier Board) as the lead SKU for Charlotte and United States programmes:

• SMARC module design: WF-RK3588S seats on the 314-pin MXM edge with the carrier holding the I/O.
• COM Express Type 6 builds: WF-RK3588S maps to the Type 6 pin-out for existing x86 carriers.
• Edge AI boxes: WF-RK3588S runs 6 TOPS NPU inference on the carrier-side thermal solution.
• Video wall controllers: WF-RK3588S drives HDMI 2.1 and DP 1.4 out through the carrier.
• Medical imaging terminals: WF-RK3588S pairs PCIe 3.0 x4 with the carrier frame grabber.
• Autonomous vehicle compute: WF-RK3588S holds -40C to 85C on the automotive-grade carrier.
• Bespoke industrial carriers: WF-RK3588S ships the signal integrity report for the customer stack-up.
• Carrier bring-up: WF-RK3588S comes with the BSP port for the carrier revision.

Partnership Models for Charlotte Buyers

The WF-Series is available to United States partners through three routes, and they can be mixed inside one agreement:

• 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 Longgang under one documentation pack covering CE, FCC, UKCA, RoHS, and REACH. A Charlotte first order on the WF-RK3588S is normally the 8GB + 64GB, SMARC 2.2 (WF-RK3588S-A) configuration at MOQ 5,000 units per shipment, four weeks for samples and six weeks for mass production.

Frequently Asked Questions

Does the WF-Series support certified Android TV or Google Mobile Services?

Answer: It depends on the platform, and AndroidSBC is explicit about the split. The WF-H618 carries the ATV 12 GMS build with Widevine L1 and Dolby Audio pre-burned at the factory. The WF-A133, WF-T527, and the Rockchip boards ship with an AOSP or Linux image by default, and a GMS build can be prepared for ODM partners who need Play Services in the field. Certification scope is agreed per project rather than assumed.

What is the difference between the nine WF-Series models?

Answer: WF-A133 is the Allwinner A133 commercial display and advertising board. WF-H618 is the Allwinner H618 OTT TV box and Android TV board. WF-T527 is the Allwinner T527 octa-core industrial control and edge AI board. WF-RK3588 is the Rockchip RK3588 8K video wall and AI computing board. WF-RK3568 is the Rockchip RK3568 industrial edge board. WF-RK3566 is the Rockchip RK3566 machine vision and HMI board. WF-RK3288 is the Rockchip RK3288 POS and signage board. WF-A133S is an Allwinner A133 SOM module for custom carrier work. WF-RK3588S is a Rockchip RK3588 SMARC 2.2 module for the same purpose.

Can AndroidSBC handle CE, FCC, UKCA, RoHS, and REACH paperwork for United States?

Answer: Yes, and the file travels with the goods rather than behind them. The pack covers CE, FCC Part 15, UKCA, RoHS 2.0, and REACH with test reports dated within the prior year. AndroidSBC will also advise on any United States-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?

Answer: 5,000 units per shipment on standard configurations, four weeks to sample and six weeks to mass produce. Where a United States partner signs a twelve-month blanket order, the MOQ per release becomes negotiable and the line will accept platform-mixed purchase orders.

Does AndroidSBC support custom Android ROM or custom Linux development?

Answer: Custom ROM and custom Linux work is part of the ODM tier. That covers proprietary Android services, a locked-down launcher, Yocto or Debian or Buildroot images, and BSP ports for custom carriers. Source access is released under NDA, and the Longgang engineering desk carries the port so the partner is not left with an unmodified vendor BSP.

What about software updates and long-term support?

Answer: Wanlin commits to a minimum seven-year supply window across the WF-Series. Security patches are back-ported across the Android and Linux firmware tracks for as long as the board is in production, and AndroidSBC provides OTA update infrastructure for partners who need to push firmware to field-deployed units. For POS and industrial programmes, the support commitment is written into the framework agreement rather than left as an understanding.

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, and Los Angeles. 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?

Answer: The DOA target is 0.3 percent over twelve months. For RMA, partners send the WF-RK3588S 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.
