Based on the SX1278 transceiver and the Atmega 328P-AU, this board serves as a great ground station to receive and send LoRa signals thanks to its clear and sharp 2.2 “LCD screen and its easy-to-use interface. Unit ships with standard but configurable software, fully customizable and open source. Board features I2C and power break for connecting external sensors and peripherals. Female SMA connector can be connected to any antenna UHF but includes a 433MHz monopole. It includes an SD card reader and can be powered by a 3.7V cell.
