This LoRa module features an ATmega4809 8bit AVR microcontroller running at up to 20MHz and with 48 KB Flash, 6 KB SRAM and 256 bytes of EEPROM in a 48-pin QFP package.

It provides two antenna connectors (SMA and UFL) for a wide variety of antenna connections.

Moreover, the cheap and easy-to-use RFM95 module enables the LoRa module to operate within the Sub-1GHz band, using only a lightweight piece of code.

With its very minimal bill of materials, it is a good choice for very cheap, customizable and easy-to-make sensor nodes.
