ExpressLRS FPV ELRS long distance ES900TX tuner ES900RX receiving module

The ES900TX and ES900RX modules are a set of long-distance 915MHz/868MHz wireless transmission equipment developed and designed based on the open source software ExpressLRS. This module is characterized by ultra-long distance, stable operation and low latency. The module is compatible with most Opentx remote controls, especially suitable for Radiomaster TX16S and Jumper T12 T16 T18 series remote controls. It is basically plug and play. We specially customized the heat dissipation module for the transmitter module, and added a 2006 cooling fan for the new version ES900TX, which can help the transmitter module operate stably at high power. The fan is plug-and-play. When the power of the transmitter module is set to 250mw, the fan automatically works. . The receiver module is very small and mini, weighing only 0.6 grams without the antenna. It is very suitable for use with various Whoop machines and Toothpick machines. Both the tuner module and the receiver module can choose 915MHz or 868MHz. We have programmed and tested them before leaving the factory.

Binding steps for the new version of ES900RX receiver:

1. Power on the ES900RX receiver, turn off the power immediately when the LED on the receiver goes out, and then repeat. After powering on the ES900RX for the third time, the LED light on the receiver will start to flash twice, which means that the ES900RX receiver enters the binding mode.

2. Connect the ES900TX or ES915TX tuner module, select the CRSF protocol in the remote control module options, then find the ELRS option, enter and select BIND. After the frequency binding is successful, the LED light on the receiver will first turn off, then flash slowly and then stay on.
