SX1268 433MHz LoRa HAT for Raspberry Pi

The SX1268 433MHz LoRa HAT is a wireless expansion module for Raspberry Pi based on the SX1268 LoRa module. The HAT operates in the 410.125-493.125MHz frequency band and comes with a 433MHz antenna. Communication with the host is provided through UART.

Alongside the standard 40-pin GPIO header for Raspberry Pi, the board features a CP2102 USB-to-UART converter and a separate UART header for connecting other host controllers. The LoRa module supports features including Wake on Radio, automatic multi-level repeating, RSSI indication, carrier sensing and wireless parameter configuration. This version supports LoRa communication but does not support LoRaWAN.
