Application matrix: 8 customization scenarios for the AS-RK3568-DQR-CUS
The AS-RK3568-DQR-CUS is one carrier platform across eight different query terminal deployments. The matrix below shows the most common OEM/ODM customization angles a mall operator technology buyer in Middle East walks through in the first scoping call.
| Scenario | Catalog board limit | AS-RK3568-DQR-CUS customization |
|---|---|---|
| Government information counter | 4.1 s first lookup, no offline index | Cached department index, offline search mirror |
| Hospital enquiry desk | 3.3 s registration lookup, no audio path | Local appointment index, on-board audio |
| Bank enquiry terminal | 3.9 s balance read, no secure element | Sub-700 ms aggregated call, secure element |
| Mall directory and price check | 22 fps map, no fuzzy tenant search | GPU composited map, local fuzzy index |
| Airport and station wayfinding | Remote render, no offline fallback | Local mirror, offline wayfinding index |
| Dual-screen enquiry plus notice | Mirrored output, 340 ms drift | Two framebuffers, per-panel proof-of-play |
| Certificate and document printing | Printer brownout, no signature lane | Budgeted print rails, on-board pad lane |
| Multi-platform query family | Four carriers, two contracts | One enclosure, one BSP train, one MOQ |
OEM/ODM workflow: 8 steps from kickoff to first article
Below is the actual OEM/ODM workflow a mall operator technology buyer in Izmir walks through when commissioning a custom self-service query terminal Android motherboard from AndroidSBC. No step is a placeholder.
- Day 0-2 — Requirements intake. A 90-minute call captures the desk format, the I/O map, the language list, the OS choice, the query workflow, the print and reader peripherals and the volume profile. Output: a one-page requirements sheet.
- Day 3-6 — Feasibility study. AndroidSBC engineers validate the SoC choice (RK3588, RK3568, RK3566, RK3399 or RK3288), the carrier I/O map, the BSP availability, the certification gap and the thermal envelope. Output: a feasibility report with go / no-go on each customization.
- Day 7-10 — Schematic and PCB layout. The AS-RK3568-DQR-CUS carrier board is laid out on a 6-layer stack-up with the customer's I/O map. Output: schematic and PCB review package.
- Day 11-14 — BSP porting. Android, Linux, Ubuntu, Debian, Kylin OS, UOS or OpenHarmony BSP is ported to the customer's OS choice, with PREEMPT_RT patches, kiosk-mode locking, secure boot, offline index support and runtime locale packs where needed. Output: a BSP build for the customer's evaluation team.
- Day 15-18 — Sample fabrication. Five to ten engineering samples are fabricated at the Shenzhen source factory, with conformal coating and stencil rework as required. Output: samples shipped to the customer by air.
- Day 19-21 — Customer evaluation. The customer's evaluation team runs thermal, EMC, query latency, print, touch calibration and field-replication tests. Output: an evaluation report with sign-off or change requests.
- Day 22-23 — Design freeze and mass-production tooling. Any change requests are absorbed, the design is frozen, and mass-production tooling is opened at the source factory. Output: a frozen Gerber and a frozen BOM.
Twenty-eight days from kickoff to first article. Ninety days from kickoff to mass production. This is the OEM/ODM rhythm that the mall operator technology buyer in Middle East learns to expect from a Shenzhen source factory that does this work for a living.
Frequently asked questions
What is the MOQ for a custom self-service query terminal Android motherboard?
Answer: 150 units for OEM (a re-spin of an existing carrier board), 500 units for ODM (a from-scratch PCB layout). Sample orders of five units are accepted with an engineering report.
How long does OEM/ODM customization take from kickoff to first article?
Answer: 28 days on the workflow described above, including schematic, PCB layout, BSP porting, sample fabrication and customer evaluation. Mass production starts around day 90.
Should I choose RK3588 or RK3568 for a query terminal?
Answer: RK3588 for dual-screen enquiry plus notice pillars, GPU composited wayfinding maps and multi-camera people analytics; RK3568 for government counters, hospital enquiry desks, bank enquiry terminals, printing counters and station wayfinding pillars where 1 TOPS and 4K dual display are sufficient; RK3566 for cost-driven single-screen enquiry tiers. AndroidSBC builds all of them on the same enclosure cut-out.
Can the terminal answer a query when the network is down?
Answer: Yes. A cached department or tenant index plus an offline search mirror keeps the enquiry desk answering questions through a patch window or a link outage, with no greyed-out search box.
Can one carrier drive the enquiry result and a second information feed?
Answer: Yes. Two independent framebuffers give per-panel resolution, refresh and rotation, so the wayfinding half keeps running while the notice half updates, with per-panel proof-of-play logs.
Can the board print a certificate and read an ID card at once?
Answer: Yes. The printer rail is current-budgeted with soft-start sequencing, the reader sits on an isolated rail, and the print job is signed and logged even if power drops mid-page.
Is there an on-board signature pad lane?
Answer: Yes. The carrier exposes a signature pad lane with pen vector capture, so the desk does not need a separate signing tablet and second PC.
Do you support multi-language enquiry interfaces?
Answer: Yes. Runtime locale packs are selected per desk with no per-language re-spin of the firmware image, including right-to-left layouts where the market requires them.
What certifications can you pre-scope for our market?
Answer: CE / FCC / RoHS standard. UL / UKCA / KC / PSE / SAA, GMS / Google EDLA and payment pre-scoping are all available on request. EMC pre-scanning is done in-house before third-party testing.
Do you accept sample and small-batch orders?
Answer: Yes. Samples ship in 1-3 days from stock where available; custom samples ship inside the 15-18 day window. Small-batch and large-volume pricing is available on request.
