Embedded Firmware Development

ESP32 and STM32 firmware development services for connected products. We write production firmware on FreeRTOS, Zephyr and embedded Linux, with OTA updates and secure boot built in from the first release.

Firmware is where many connected products slip. We take ownership of it end to end: board bring-up on your hardware, drivers for your sensors and peripherals, power management for battery devices, wireless stacks, and the link to the cloud.

Because we also design PCBs and build cloud backends, we can debug across the whole system instead of passing problems back and forth between vendors.
