About this Gig

Please contact me before ordering so we can confirm your hardware, requirements, and project scope.

I develop STM32 firmware in C for embedded and IoT projects, with a focus on bare-metal programming and low-power devices.

My experience includes household alarm and security products, certification support, and products manufactured in quantities exceeding 10,000 units.

I can help with:

  • Sensor and module integration
  • UART, SPI, I2C, ADC, timers, and GPIO
  • LCD displays and device control logic
  • Battery monitoring and low-power operation
  • 433 MHz wireless communication
  • Wi-Fi, NB-IoT, and Tuya integration

The Basic package covers one simple sensor or module on existing STM32 hardware, with an agreed function. Delivery includes source code, setup notes, and one revision within the original scope.

Larger firmware projects and wireless or cloud integration require a custom quote. Hardware, PCB fabrication, shipping, and certification fees are not included.

Please share your MCU model, schematic or pin connections, module datasheet, and required behavior. We will agree on how to test the firmware before starting.
