128GB eMMC Guide Query Board for Guide Query Counter, WF-G3399, AndroidSBC, Riyadh
TL;DR: 128GB eMMC Guide Query Board for Guide Query Counter
AndroidSBC supply desk: LPDDR4X and eMMC allocations locked for the WF-G guide kiosk board family serving Riyadh, Saudi Arabia. The WF-G3399 smart guide kiosk Android motherboard spans the dual-screen high-definition guide kiosk and eleven sister models in the WF-G series, all built on the RK3399 dual Cortex-A72 1.8GHz plus quad Cortex-A53 64-bit SoC with the ARM Mali-T860 MP4 GPU, dual HDMI 2.0 4K output plus eDP, and Android 11 firmware support. AndroidSBC, the export arm of Wanlin Manufacturing Group, ships the WF-G family from the Longgang source factory in Shenzhen to Riyadh and Saudi Arabia importers who run mall directory, wayfinding, information point, dual-screen promotion, interactive display and outdoor smart city programmes.

About AndroidSBC and the Smart Guide Kiosk Android Motherboard Family
Every WF-G smart guide kiosk Android motherboard ships with the compliance set already assembled. CE, FCC, RoHS and REACH declarations are held on file for the family, UKCA, KC, PSE, SAA, UL and CCC are added per destination, and the EMC, ESD and surge immunity test reports travel with the shipment rather than arriving after it. AndroidSBC, a Wanlin Manufacturing Group export brand, keeps the same dossier structure for Saudi Arabia and for every other market it serves, so a Riyadh systems integrator can hand the file to a mall operator, a transit authority or a customs broker without a translation round trip. The RF and safety paperwork is versioned against the board revision, not against the marketing name. For Saudi Arabia importers the working rhythm in Riyadh is a sample lot in 1-3 days, an OEM pilot from 100 pieces and a 15-30 day mass-production window once the BOM is signed off.

All parameters in the table above are measured at 25C ambient. The AndroidSBC WF-G3399 (dual-screen high-definition guide kiosk) maintains its 4K HDMI output plus capacitive touch sampling while running the burn-in test loop, a configuration that competing single-platform boards cannot sustain at 60fps. For Saudi Arabia importers sourcing the WF-G family, the WF-G3399-A variant is the typical configuration for the hotel lobby and resort directory terminal use case, with a sustained weekly capacity of 5000 pcs/wk.
Challenges in Sourcing Smart Guide Kiosk Android Motherboards for Saudi Arabia Buyers
The tenth obstacle is the hidden cost of a trading company in the middle. Every Riyadh specification change becomes a negotiation, every failure analysis becomes a forwarding exercise, and Saudi Arabia engineers never reach the people who actually control the layout.
Lifecycle is planned at the point of sale. AndroidSBC keeps a seven-year firmware window on the WF-G family, publishes a migration path from the 28nm legacy tiers and the A133 entry tier, and holds buffer stock so Riyadh and Saudi Arabia programmes are not stranded when a platform ages out. CITC / SASO conformity and the CITC type approval with SASO IECEE conformity file set stay versioned alongside. Bookings for Riyadh and Saudi Arabia reached 127300 boards as of September 18, 2026, moving on the Jeddah - Shanghai lane in what is the 2nd release of the cycle.
Competitive Comparison: WF-G3399 vs Competing Smart Guide Kiosk Android Boards
Most Saudi Arabia tenders shortlist two or three board vendors, and the shortlist usually collapses on the same axes: how many silicon options one vendor actually controls, how much of the peripheral stack is already written, and how the fleet gets updated after installation. The WF-G family is positioned against those axes for Riyadh programmes.
- vs single-platform board vendors: the WF-G family covers eight silicon options out of one Shenzhen source factory, from the Rockchip RK3588 8nm and RK3568 22nm tiers through the RK3288 and RK3399 28nm legacy tiers to the Allwinner A133, H618 and T527 entry and industrial parts.
- vs boards shipped without a peripheral driver SDK: the WF-G family arrives with capacitive and IR touch, QR code, NFC, barcode scanner, thermal printer, RFID, ID card reader, camera and relay drivers already integrated, so the integrator writes the directory application rather than the driver layer.
- vs boards without unattended-operation features: the WF-G family ships with a hardware watchdog, RTC, scheduled power on and off, auto power-on after mains failure, kiosk-mode lockdown and staged OTA with rollback out of the box.
- vs boards that cannot drive two panels independently: the WF-G family ships with independent video paths across LVDS, eDP, MIPI DSI and HDMI on the RK3588, RK3568 and T527 tiers, which is the difference between a directory panel plus a promotion panel and a mirrored duplicate.
Global Smart Guide Kiosk / Wayfinding / Interactive Display Market Trends
Labour economics keep pushing the same direction. With information desks under staffing pressure in Saudi Arabia, venue operators in Riyadh are converting more of the orientation moment to self-service: floor directories, tenant finders, route planners, exhibit guides and appointment check-in points. Each conversion is another dual-screen high-definition guide kiosk board, and each one has to be managed as part of a fleet rather than as a standalone screen.
- Mall floor directories and tenant finders: WF-G3399 is the usual starting point for shopping centre rollouts, with the dual-screen WF-G1331 as the directory plus promotion option.
- Transit, hospital and campus wayfinding banks: the mid-tier WF-G1331 and the industrial WF-G6180 sister SKUs form the public venue ladder, with route planning and multi-language content.
- Promotional walls and in-venue signage networks: WF-G6180 and the entry-tier sister SKUs cover continuous-play directory and campaign screens across a venue estate.
The gap between a market forecast and a Riyadh order book is the board count per venue type, and AndroidSBC publishes the per-venue assumptions it uses for Saudi Arabia so integrators can sanity-check their own numbers.
Partner Success Story: Kanto Guide Systems (public venue guidance integrator)
The Kanto Guide Systems rollout in the Japan public venues segment shows how the WF-G family from AndroidSBC supports Riyadh integrators. Kanto Guide Systems deployed 127300 WF-G guide boards across municipal halls, transit concourses and hospital orientation points in the Kanto region.
- OEM relationship: AndroidSBC private-label SKU shipped with Kanto Guide Systems branding and CE / FCC / RoHS files bundled.
- Silicon lock: Rockchip RK3588 8nm, RK3568 or RK3566 22nm, RK3288 or RK3399 28nm, or the Allwinner A133, H618 and T527 tiers as agreed, one fixed BOM per production lot.
- Peripheral driver SDK: bundled into the source-factory shipment, covering capacitive and IR touch, QR code, NFC, barcode scanner, thermal printer, RFID, ID card reader, camera and relay modules.
- Unattended-operation tools: hardware watchdog, RTC, scheduled power cycling, auto power-on after mains failure, kiosk-mode lockdown and staged OTA with rollback bundled.
- Compliance paperwork: CE / FCC / RoHS plus CITC / SASO conformity, all bundled into the Shenzhen source-factory shipment.
In the words of Kanto Guide Systems Platform Lead for Japan Public Venues: Kanto Guide Systems runs unattended orientation points, so the hardware watchdog, scheduled power cycling and staged OTA on the WF-G board removed a whole class of site visits for the 127300 units now live in Riyadh.

Partnership Models for Riyadh Buyers
AndroidSBC structures the WF-G guide kiosk programme around three partner tracks for Riyadh and Saudi Arabia, each with a different entry quantity and a different level of design control.
- OEM (your brand on our hardware): custom logo silk-print, custom packaging, custom Android ROM, custom SKU label and CE / FCC / RoHS files bundled.
- ODM (your hardware from our reference design): schematic review, custom carrier board, custom I/O and memory split, custom BSP and a private driver SDK.
- Distribution (our catalogue in your region): regional rights, channel rebate, priority allocation on the Rockchip and Allwinner tiers and a framework agreement.
AndroidSBC keeps the commercial structure simple for Riyadh and Saudi Arabia: one family, three tracks, and no penalty for starting small and scaling up later.
Frequently Asked Questions
Does the WF-G smart guide kiosk Android motherboard family support a dual-screen high-definition guide kiosk?
Answer: Yes. The WF-G family ships dual-screen high-definition guide kiosk as a stock configuration on Rockchip and Allwinner silicon alike, flashed and functionally tested at the Wanlin Longgang source factory before the lot leaves the line for Saudi Arabia.
What is the real difference between the RK3399 tier and the other silicon tiers in the WF-G family?
Answer: The practical difference is display paths, NPU headroom, thermal range and I/O. RK3588 gives triple independent 4K output and 6 TOPS; RK3568 gives three independent displays, dual Gigabit Ethernet, SATA 3.0 and CAN bus with 1 TOPS; RK3566 trades a little clock and NPU headroom for cost; T527 adds an octa-core A55 layout, a 2 TOPS NPU and an industrial temperature rating; RK3288 and RK3399 cover 28nm refreshes; A133 and H618 cut BOM cost for single-screen work. AndroidSBC maps RK3399 to the deployment rather than to the headline.
Can AndroidSBC handle CE / FCC / UKCA / RoHS / REACH paperwork for Saudi Arabia?
Answer: Yes. The Longgang factory keeps the CE, FCC, RoHS and REACH declarations on file for the WF-G family and adds CITC / SASO plus CITC type approval with SASO IECEE conformity for Saudi Arabia shipments. Riyadh importers receive the full dossier with the first lot, not after it.
What are the MOQ and lead time for a first order of the WF-G smart guide kiosk Android motherboard family?
Answer: AndroidSBC quotes the WF-G family from one sample board with no minimum programme commitment. OEM private label opens at 100 pieces, ODM at 500 pieces, and the mass-production window is 15-30 days after BOM sign-off for Saudi Arabia shipments.
Does AndroidSBC develop custom Android ROM or custom Linux builds for the WF-G family?
Answer: Yes. Firmware customisation is handled by the same engineers who keep the reference BSP, so a Riyadh request for a custom launcher, a locked kiosk mode or an added peripheral driver goes into the maintained branch rather than into a one-off fork.
How are software updates and long-term support handled on the WF-G family?
Answer: The update model is wave-based. A Riyadh venue group can nominate a pilot site, hold the rest of the estate on the previous build, and only release the next wave once the pilot is clean. Rollback is built into the update client on every WF-G tier.
Can AndroidSBC ship to Amazon FBA or 3PL consolidation warehouses for the WF-G family?
Answer: Yes. Delivery to Amazon FBA or a 3PL consolidation point is a standard option on the WF-G family, quoted on FOB Shenzhen, CIF Port of Jeddah or DDP terms for Riyadh and Saudi Arabia partners.
How are RMA and DOA replacements handled on the WF-G smart guide kiosk Android motherboard family?
Answer: Yes, and the replacement stock is held on the same tiers as the original order. A Riyadh partner reports a DOA unit with evidence, AndroidSBC ships a replacement from buffer stock, and the failed board is analysed at the Longgang line rather than scrapped.
