A great module!

This unit is awesome after figuring out how to update the firmware and getting the v2 lua scripts set up.
Module has a labeled boot button on the board inside the shell that needs to be pressed the entire time firmware is being flashed via uart, if the flash shows "error" or times out. Also, make sure RGB led is selected in elrs configurator.
After the successful flash, this unit runs flawlesssly. Even the leds and push button works as it should.
Flashed version 2.5.1 and it is perfect!

Solid Elrs module for the price.

The module was good for the price. With updating the firmware to V 2.3.0, it was running nice for racing and long range freestyle.
