Embedded product development team.
Full-stack embedded product development: Firmware/Software, PCB design, mechanical/enclosure engineering, and graphical user interfaces (GUI) built with LVGL and TouchGFX. We ship the idea to production with a single team and low cost.
We are a team specialize in this field.
Most clients start with one and end up handing us the whole stack, because the handoffs between them are where products usually stall.
Firmware
Embedded firmware for MCUs, IoT device and industrial equipment. Written to your spec, reviewed and maintainable after transfer.
Hardware & PCB
Concept to manufacturable board: schematic capture, layout, DFM review and bring-up for consumer, industrial and IoT products.
Embedded GUI & HMI
Device GUI built with LVGL, TouchGFX, GUIx and custom UI frameworks with screen flows designed alongside the firmware, optimize smooth rendering at low CPU and low power consumption.
Software
The android iOS, Windows, Linux application build to work with firmware. That make smooth working from device to app and IoT cloud.
Production support
Automated test software, test jigs and batch flashing scripts, self-test, component verification and sync into your existing production management system.
Skills
Bring your idea to production ready
Requirement & idea
Share your idea or requirement, and we will review it with you and advise on the best approach.
Scope & quote
Written breakdown of deliverables, risks and milestones with a price against each one.
Development
We build in your repository and share a working demo every week, so you can see the progress at any time — no surprise at the end.
Release
You receive documented source code, test jigs and flashing tools. Everything your factory or your next engineer needs to keep the product running without us.
