  1. get a samd21 microchip device
  2. The hardware can run, and the data can be printed through the serial port
  3. Port modbus protocol stack, such as freemodbus https://github.com/RT-Thread-packages/freemodbus

Hi there! I really appreciated your breakdown of the Modbus RS485 setup; it's often tricky to navigate these protocols. Could you share more about common pitfalls when configuring devices? I'm curious how you tackle those challenges, especially in larger networks. Thanks for sharing such valuable insights!
