Retail O2O Terminal Board, WF-G3399, AndroidSBC, Colombo

TL;DR: Retail O2O Terminal Board

AndroidSBC field desk: guide kiosk rollout map updated across retail, transport, healthcare and hospitality venues serving Colombo, Sri Lanka. 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 Colombo and Sri Lanka 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

Supply continuity on the WF-G family is handled the way a venue estate actually consumes boards: a pilot lot first, then a rolling programme. AndroidSBC holds buffer stock on the Rockchip and Allwinner tiers, quotes a 1-3 day sample lead and a 15-30 day mass-production lead, and locks the BOM at the start of each production lot so a Colombo programme does not silently change silicon between the pilot and the ramp. For Sri Lanka buyers running multi-site rollouts the export desk schedules lots against mall opening dates and venue handover milestones, and ships FOB Shenzhen, CIF destination port or DDP, whichever the integrator has credit and customs capacity for. Certification, carton labelling and palletisation for Sri Lanka are prepared in Shenzhen by the export desk before the Colombo shipment leaves, and the test reports stay versioned against the board revision.

WF-G3399 Technical Specifications

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 Sri Lanka 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 Sri Lanka Buyers

The third obstacle is certification sequencing. Sri Lanka customs and venue operators ask for different files, and a Colombo programme that orders boards before the compliance dossier is assembled ends up storing stock it cannot install.

Fleet management is part of the reference image. The WF-G family ships with staged OTA, rollback, remote configuration and device telemetry hooks, so a Colombo rollout in Sri Lanka can be updated in waves rather than all at once, with TRCSL / SLSI conformity and TRCSL type approval with SLSI import conformity paperwork moving with the lot through Port of Colombo. AndroidSBC booked 152800 boards for Colombo and Sri Lanka on the Colombo - Singapore lane as of September 18, 2026, the 3rd release on this programme.

Competitive Comparison: WF-G3399 vs Competing Smart Guide Kiosk Android Boards

A board quotation is easy to compare and a platform decision is not. For Colombo integrators the WF-G family is usually measured against five-option or single-platform competitors on silicon coverage, dual-screen capability, thermal range and the update path that Sri Lanka rollouts depend on.

• 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

Screen estates keep pulling board demand: dual-screen high-definition guide kiosk programmes in Sri Lanka are the near-term driver and Colombo integrators are quoting against 2026 delivery windows. Grand View Research sized the global interactive kiosk market at USD 34.79 billion in 2024 and models a 7.2% CAGR to USD 52.74 billion by 2030, with hardware holding more than 44% of revenue. The practical read for Colombo is that the dual-screen high-definition guide kiosk board is a platform decision that locks in the content stack for the life of the estate.

• Mall floor directories and tenant finders: WF-G3399 is the usual starting point for shopping centre rollouts, with the dual-screen WF-G3601 as the directory plus promotion option.
• Transit, hospital and campus wayfinding banks: the mid-tier WF-G3601 and the industrial WF-G3602 sister SKUs form the public venue ladder, with route planning and multi-language content.
• Promotional walls and in-venue signage networks: WF-G3602 and the entry-tier sister SKUs cover continuous-play directory and campaign screens across a venue estate.

Two numbers decide a Sri Lanka guide kiosk programme: how many screens a venue actually needs, and how many years the estate has to be supported. AndroidSBC plans the WF-G family against both and shares the model with Colombo integrators on request.

Partnership Models for Colombo Buyers

Entry into the WF-G family is available on three tracks for Colombo and Sri Lanka buyers, and they are designed so a partner can move between them without re-qualifying the platform.

• 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.

For Sri Lanka partners the decision is commercial, not technical: the same WF-G board ships on all three tracks, and the difference is how much of it carries the partner brand in Colombo.
