This is a mainboard based on the ATmega328 microchip and Lora Module designed for ultra-long-range, high interference immunity and low rate data transfer. Perfect for IoT projects.

Maduino Lora Radio is a mainboard based on the ATmega328 and 915MHz module. The LoRa Radio allows the user to send data and reach extremely long ranges at low data rates. It provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption. We use the Arduino pro mini 3.3V 8MHz bootloader on this board and use the CP2104 as a USB to serial to upload the code by Arduino IDE.
