The ATMega328 LoRaWAN Node is the successor of the ProMini LoRaWAN Node. As the ProMini version, it is powered by an ATMega328, running at 3.3V and 8Mhz, but instead of using an Arduino ProMini board, it uses a barebones ATMega328. This removes the issues of the ProMini board such as weird pin layout for the I2C pins, the always-on LED, and the power regulator. There have been some additional fixes to the ProMini Node board, such as:

  • Reordering the power pins so you can solder in screw connectors as well
  • Strain relief holes next to the power pins
  • Two mounting holes
  • No more voltage measurement for the 3.3V/Vcc bus, as this can be done internally on the ATMega
