Capabilities

A hardware team that also writes the software

The hardware is the part that is hard to buy: schematic, PCB layout, structure, tooling, and the silicon judgement behind them. The apps, mini programs and server are built by the same team — not because software is the differentiator, but because splitting it across two vendors is what makes connected products late.

Silicon we design on

Four compute tiers, domestic and overseas vendors, with FAE support direct from the chip makers. Selection follows your cost, supply and certification constraints — we are not defending one architecture.

Representative parts per tier. If your project needs silicon we have not shipped, we will say so rather than learn on your tooling budget.

In-house teams

These disciplines are ours. Where we depend on partners — assembly, certification labs — we say so.

Silicon selection

NPU-equipped Linux SoCs, WiFi and Bluetooth SoCs, MCUs and display drivers — domestic and overseas parts, with FAE support direct from the vendor rather than a distributor in between.

Hardware & structure

Schematic design, PCB layout, ID and MD, tooling. DFM review before a mould is cut, so surprises land in CAD rather than in steel.

Firmware

Low-power embedded firmware across BLE, LTE Cat-1/M1, WiFi and Zigbee stacks. OTA infrastructure included.

Algorithms

PPG heart rate and SpO2, motion classification, far-field audio front-end, and on-device vision models quantised for embedded NPUs.

Apps & mini programs

iOS and Android, plus WeChat and Alipay mini programs — which matter more than an app in China, where nobody downloads one to try a device. White-label, or an SDK for your existing app.

Server & cloud platform

Device provisioning, MQTT and message pipeline, OTA campaigns, user and permission model, and the admin console your support team actually uses. Deployed to your cloud account or ours, with data residency by region.

Test engineering

Functional test fixtures designed per product, plus the drop, ageing and IP verification plan the partner line runs against.

Compliance planning

We map the route — CE, FCC, RoHS, REACH, BQB, EN 71 — pick the lab and schedule it alongside tooling. Testing is done by accredited labs, not by us.

Production

We do not own an assembly line. Production runs at partner factories we qualify, under our engineering supervision and our test plan — and we will name the line and arrange the audit before you place an order.

What we hold ourselves to

  • The partner line is named before an order, never after
  • Our test plan and fixtures, run on their line
  • Our engineer present for pilot builds
  • Full-function test on 100% of units, not a sample
  • Drop, ageing and IP verification defined per product
  • You are welcome at the audit, in person or by video

Designed toward — not certificates held

  • CE
  • FCC
  • RoHS
  • REACH
  • BQB
  • EN 71

Ask the awkward questions.

Who builds it, on whose line, tested how, certified by whom. We would rather answer that in the first call than in a dispute.
