Industrial Wide Temperature Board, WF-H618, AndroidSBC, Fort Worth
TL;DR: Industrial Wide Temperature Board
SHENZHEN, China, September 10, 2026 - The WF-H618 board line at Wanlin Longgang closed lot 205 this week. 21,530 units are now booked for Fort Worth, United States, shipped FOB with the full certification file attached.
AndroidSBC head-to-head comparison of the WF-Series against the previous board generation serving Fort Worth, United States. What United States importers get from the WF-Series is platform breadth from one factory. Three Allwinner parts and four Rockchip parts sit under one part-number scheme, with two SOM modules for customers who design their own carrier. Wanlin builds all nine at Longgang in Shenzhen, and the export desk issues one certification pack per lot covering CE, FCC, UKCA, RoHS, and REACH.

About AndroidSBC and the Allwinner H618 Board Family
The WF-Series is a nine-board custom line from AndroidSBC, the export arm of Wanlin Manufacturing Group in Shenzhen. Three Allwinner platforms (A133, H618, T527) and four Rockchip platforms (RK3588, RK3568, RK3566, RK3288) sit under one part-number scheme, with two SOM modules for carrier-board projects. 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 REACH file per lot. For United States importers, the line covers the OTT box, commercial display, industrial control, edge AI, and POS categories that a Fort Worth distributor is most often asked to quote.
WF-H618 Technical Specifications
| Parameter | AndroidSBC WF-H618 (OTT TV Box and Android TV Board) | Industry Average |
|---|---|---|
| Processor | Allwinner H618 quad-core ARM Cortex-A53 1.5GHz 64-bit + Mali-G31 MP2 GPU | Quad-core older 28nm or 40nm SoC |
| Process node | 28nm low-power | 28nm-40nm mixed |
| GPU | Arm Mali-G31 MP2 (OpenGL ES 3.2, Vulkan 1.1) | Mali-450 or older |
| Video decode | H.265 8K@24fps + H.264/VP9/AVS2 4K@30fps hardware decode | 1080p@60fps hard limit |
| Video encode | H.264 4K@25fps + JPEG 1080p@60fps | 1080p@30fps encode |
| Display output | HDMI 2.0 4K@60fps + CVBS OUT | HDMI 1.4 1080p |
| HDR | HDR10 / HDR10+ / HLG / HDR Vivid | HDR10 only or no HDR |
| Memory | 2GB / 4GB LPDDR4 | 1GB-2GB only |
| Storage | 8GB / 16GB / 32GB eMMC 5.1 onboard | 8GB-16GB only |
| Wireless | WiFi 6 + Bluetooth 5.0 BLE module | WiFi 4 / no BLE |
| Wired network | 10/100/1000M Gigabit Ethernet + USB 2.0 HOST/OTG | 100M Ethernet only |
| OS support | Android 12 (ATV 12) + Android 14 (ATV 14) + Ubuntu / Debian / Armbian | Older Android 7-9 |
All parameters in the table above are measured at 25C ambient. The AndroidSBC WF-H618 (OTT TV Box and Android TV 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 2GB + 8GB (WF-H618-A) variant is the typical configuration for the OTT TV box and Android TV stick use case, with a sustained weekly capacity of 5,000 pcs/wk on the Longgang line.
Challenges in Sourcing OTT TV Box and Android TV Board for United States Buyers
For United States procurement teams, the first surprise on the ott tv box and android tv board line is rarely technical. It is that the sample arrives on time and the production lot does not, because the Allwinner H618 allocation cannot be conjured from broker stock when a 21,530-unit order is confirmed. The second risk sits in the firmware image. Boards that pass a bench boot can still fail the certified stack the buyer's channel requires, and that gap usually appears during inbound inspection rather than before shipment.
Documentation is the third item on the list. A CE mark without a matching Declaration of Conformity and Technical File is not a marking problem, it is a customs problem, and it tends to surface after the goods are already on the water. AndroidSBC's approach is to close the gap at the factory gate. The certified stack is loaded on the Longgang line, the burn-in record is traceable per unit barcode, and the CE and FCC test reports are dated inside twelve months and shipped with the lot. The nine WF-Series boards span OTT TV box, Android TV stick, streaming media player, hybrid set-top box, hotel IPTV receiver, smart screen, single-board computer, and IoT gateway, with three memory configurations per model for Fort Worth buyers who need a standard SKU rather than a custom build.
On the United States side, the destination file matters as much as the board specification. 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. The export desk prepares 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, and releases it with the standard multi-market pack (CE, FCC, UKCA, RoHS, REACH). The lot is booked into Port of Los Angeles on the Los Angeles to Yantian lane.
Competitive Comparison: WF-H618 vs Competing H618 Boards
Competing boards in the ott tv box and android tv board category sort into three camps: cheap legacy SoC boards, mid-range Cortex-A55 boards with certification, and 64-bit boards with real expansion. The WF-H618 is in the last camp, and its edge is Allwinner H618 plus a display path that holds under a continuous loop rather than a bench test.
- vs A133 4K@30fps-only boards: the H618 8K H.265 hardware decode doubles the decoder throughput ceiling.
- vs 1080p-only Cortex-A7 boards: the quad-core 64-bit Cortex-A53 adds AES-128 hardware crypto for Widevine L1.
- vs quad-core Cortex-A55 boards: the Cortex-A53 1.5GHz matches the A55 on burst frequency while keeping better software continuity for legacy SoC boards.
- vs older Mali-450 GPU boards: the Mali-G31 MP2 is two generations newer, with Vulkan 1.1 and OpenGL ES 3.2 support.
Global OTT Set-Top Box and Android TV Market Trends
The OTT Set-Top Box and Android TV curve is what United States importers read before committing to an ott tv box and android tv board programme. The number they quote is 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, Android TV Box Market Report, 2025-2035), which serves as the closest public proxy for Android silicon demand. For Fort Worth that resolves into three demand patterns across the WF-Series order book:
- OTT TV box: WF-H618 runs the ATV 12 launcher with the GMS stack pre-burned.
- Display and signage refresh cycles: a longer content loop and a higher panel resolution now define the refresh trigger. The WF-H618 board carries that headroom without a board change.
- Streaming media player: WF-H618 holds an 8K H.265 loop while the 4K HDMI 2.0 output stays locked at 60fps.
Analysts covering the OTT Set-Top Box and Android TV space point to the same pattern in United States: order books are being built around platform breadth rather than a single part number.
Across those three segments, Fort Worth procurement has been shifting from spot quotes to framework agreements with a one-lot-per-month cadence, particularly where a retail or hospitality programme needs a twelve-month shipping window.

Field Report: a high-brightness outdoor display trial in Fort Worth, where 21,530 units of the WF-H618 board are running behind sunlight-readable panels
Reporter Xu Feng, on the ground in Fort Worth, United States. The trial ran the WF-H618 boards inside a sealed enclosure with no active cooling and a panel brightness pushed to its ceiling. Internal board temperature stabilised below the throttle point across a full day of direct sun, and the content loop ran without a dropped frame from morning to evening.
The QA lead noted that the WF-H618 lot was the third consecutive run to clear the aging bench without a retest.
The inspection confirmed three things on the spot: the WF-H618 units hold the burn-in with a yield above 99.51 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-H618 Application Scenarios
The WF-Series fits nine application lanes, with the WF-H618 (OTT TV Box and Android TV Board) as the lead SKU for Fort Worth and United States programmes:
- OTT TV box: WF-H618 runs the ATV 12 launcher with the GMS stack pre-burned.
- Android TV stick: WF-H618 fits the 56x85mm dongle envelope with the IR receiver onboard.
- Streaming media player: WF-H618 holds an 8K H.265 loop while the 4K HDMI 2.0 output stays locked at 60fps.
- Hybrid set-top box: WF-H618 pairs the Gigabit Ethernet port with the USB 2.0 OTG path.
- Hotel IPTV receiver: WF-H618 accepts property-wide APK plus DRM credential push.
- Smart screen: WF-H618 drives the MIPI-DSI panel through the 26-pin expansion header.
- Single board computer: WF-H618 boots Debian, Ubuntu, and Armbian from the same image set.
- IoT gateway: WF-H618 runs the Matter-ready stack on OpenWrt 23.
Partnership Models for Fort Worth Buyers
AndroidSBC opens the WF-Series 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 Fort Worth buyers, a typical first order on the WF-H618 is the 2GB + 8GB (WF-H618-A) configuration at MOQ 5,000 units per shipment, with a four-week sample lead time and a six-week mass production lead time.
Frequently Asked Questions
Does the WF-Series support certified Android TV or Google Mobile Services?
Answer: On the WF-H618, yes: ATV 12 with GMS plus Widevine L1 and Dolby Audio, burned on the Longgang line for every lot. On the remaining eight boards the default image is AOSP or a Linux distribution, because those boards usually sit in commercial display, industrial, or POS deployments where Play Services is not a requirement. AndroidSBC will build a GMS image for ODM customers who ask for it and will state clearly which boards carry which certification.
What is the difference between the nine WF-Series models?
Answer: Nine boards, seven silicon platforms, two of them modules. WF-A133 and WF-H618 and WF-T527 are the Allwinner entries for commercial display, OTT TV, and industrial edge respectively. WF-RK3588, WF-RK3568, WF-RK3566, and WF-RK3288 are the Rockchip entries for 8K video wall, industrial edge, machine vision, and POS. WF-A133S and WF-RK3588S are board-to-board SOM modules sized for customers who want to design the carrier themselves. Each board carries three memory configurations.
Can AndroidSBC handle CE, FCC, UKCA, RoHS, and REACH paperwork for United States?
Answer: That is handled in-house. Each lot leaves Longgang with a Declaration of Conformity and a Technical File holding the CE, FCC Part 15, UKCA, RoHS 2.0, and REACH documents, all dated inside twelve months. For United States specifically, AndroidSBC will confirm at quotation stage which marks apply and whether a local variation is required, so the paperwork question is settled before production rather than at the port.
What are the MOQ and lead time for a first order?
Answer: MOQ is 5,000 units per shipment for the standard memory configuration of any WF-Series board. Sample lead time runs four weeks and mass production six weeks. Partners who prefer a twelve-month blanket order with a monthly lot release can negotiate the MOQ down, and mixed-platform orders on one purchase order are accepted.
Does AndroidSBC support custom Android ROM or custom Linux development?
Answer: Yes. Under NDA, AndroidSBC delivers custom Android ROM work with proprietary services, custom Linux images on Yocto or Debian or Buildroot, and BSP ports for customer carriers. The engineering desk at Longgang performs the port itself, which matters because an unmodified vendor BSP rarely matches a customer carrier revision.
What about software updates and long-term support?
Answer: The commitment is seven years minimum on supply, with security patches back-ported across the Android and Linux tracks. AndroidSBC also runs an OTA service that partners can use to push firmware to deployed units. On POS and industrial programmes, that commitment is written into the contract, because a fleet in the field is only as good as the update path behind it.
Can AndroidSBC ship to Amazon FBA warehouses or 3PL consolidation points?
Answer: Yes, including DDP into Amazon FBA in the US, EU, and Japan, plus 3PL consolidation points in Hong Kong, Singapore, Rotterdam, and Los Angeles. Cartons are labelled to FBA inbound spec and the declaration names Longgang as the origin. Partners who consolidate in Hong Kong usually take FOB Yantian and handle the last leg themselves.
How does AndroidSBC handle RMA or DOA replacements?
Answer: AndroidSBC targets a 0.3 percent DOA rate across the WF-Series, measured over the prior twelve months. On RMA, the partner returns the faulty WF-H618 unit to Longgang with its burn-in barcode, and a replacement ships within ten business days. Because the burn-in record is attached per unit, the failure analysis normally comes back with a root cause rather than a credit note.
