Hardware & Software Development Services
Embedded Software & Firmware Development
Custom MCU, RTOS and device firmware development, including sensor drivers, BLE connectivity, power optimization and OTA updates for new or existing hardware.
Scope & Deliverables
We develop firmware around your board, protocols and operating requirements, then test sampling, connectivity, sleep modes and updates on real devices. We can work alongside your app, cloud or hardware team.
Deliverables to agree before development
- Firmware code and build instructions for the agreed scope
- Communication protocol and interface documentation
- Device test records and release notes
Deliverables depend on the agreed scope. Code, design files, third-party licenses and maintenance arrangements are agreed before work begins.
What to share
Share schematics, sample boards, component documentation and protocols, along with known issues or the features you want to add.

Frequently asked questions
Can you develop firmware for our existing hardware?
Yes. We first review the board documentation, debug interfaces and available samples, then agree on scope and integration testing.
How much can battery life improve?
This requires measurements. Power use depends on the hardware, communication frequency and operating modes. We measure each state before identifying possible improvements.
