[Introduction]:The EWM700-2G4T20DXN is a new generation wireless receiver module developed based on the ExpressLRS open-source project. It features long communication distance, low latency, high refresh rate, strong anti-interference capability, and flexible configuration. The EWM700 series uses the ESP8285+SX1281 chip solution, operates in the 2.4GHz band, supports TTL level input and output, and has a maximum output power of 100mW. It is suitable for applications such as UAVs, remote control, flight control, surveying, and model aircraft.

Note:

(1) The firmware version of the remote control/high-frequency head/transmitter must match the receiver, i.e., version 3.0; otherwise, frequency matching will not be possible  

(2) ELRS receivers do not have a pairing password at the factory
