TOSR-04

The board :

The purpose of this project is to write and flash a custom firmware in the MCU powering this board. Indeed, this relay board was meant to be controled by sending very poorly designed serial commands which I want to get rid of !

The manual :

The user guide is available here if you want to learn more about this module's capabilities

What I am planning to do :

  1. Reverse engineer the schematic of this board (because it is not available) (IN PROGRESS)
  2. Find the best way to flash a custom firmware on the ATMEGA328PU (TO DO)
  3. Write a custom firmware for it (TO DO)
