This LoRa radio module is based on the Atmega328P and RFM98 433MHz radio module. The main chip Atmega328P clocked at 8 MHZ and at 3.3V logic. It uses the Arduino pro mini 8Mhz 3.3V bootloader, usage same as the Arduino pro mini. Besides that, it also has 32K of flash and 2K of RAM.

There is on-board 3.7v 14500 battery holder, that makes you use anywhere you like. There are two IIC ports, two analog ports (A0, A1) and two digital ports (D3, D4) on this LoRa radio node.

This LoRa radio node uses the extra space left over to add an RFM9x LoRa 433 MHz or RFM95 LoRa 915 Mhz radio module. They do work quite well for small data packet transmission when you need more range than 2.4 GHz (BT, BLE, WiFi, ZigBee).
