 Supported module types: **SX126X**, **SX127X** and other modules supported by RadioLib.
 
 Modules, which are used by users and known to work
-- **SX126X** (**suggested**, 1W modules will provide decent coverage for APRS, stable frequency suitable for < 125 kHz BW at 433 MHz, 5V from USB power bank is enough to power it, have additional LNA)

 This is small universal ESP32 devkit LoRa prototyping board for RA-01 or E22-400M30S modules on the same board. Suitable for two different ESP32 devkit types with different pinouts. Pinout configuration is done via solder pads.
 
-To be used with firmware from https://github.com/sh123/esp32_loraprs or others.
