It is fully compatible with all ExpressLRS 2.4GHz transmitters and modules.

Troubleshooting Guide

ExpressLRS uses the LED to communicate the status of the transmitter/receiver. The conditions and status LED are as follows:

Led Indication: Status

Solid on: Connected to a transmitter, or bootloader mode enabled

Double blink then pause: Binding mode enabled

Slow blink 500ms on/off: Waiting for connection from transmitter

Triple blink then pause: Connected to transmitter but mismatched model-match con-figuration

Medium speed blink 100ms on/off: Radio chip not detected
Fast blinking 25ms on/off: WiFi mode enabled
