Procedure:
Bind procedure:
- Supply power to the ES900RX, wait until the red LED on the ES900RX are off, immediately turn off the power, and then repeat again the above steps. When the ES900RX is powered on for the third time, the red LED light will start to double flash quickly, which means that the ES900RX enters the binding mode
- Insert the ES900TX module to Radio transmitter, and choose External RF mode to CRSF protocol, then you can find ELRS menu from the Radio systems, Enter into ELRS and press [Bind], the Red LED on the ES900RX module will turning off then start blinking slowly and finally getting to be solid , this means bind successfully.
ES900RX firmware update by wifi procedure:
- Make the ES900RX enter into Bind mode and then wait around 1 minute and don’t bind with it , then the ES900RX would get into Wifi mode automatically, you could connected the wifi hot pot “ExpressLRS RX” by enter the password “expresslrs”
- Visit the firmware update website by enter “10.0.0.1” , and choose the correct firmware then click “update” , wait for around 1~2 minutes, the update progress would finished and you can find “firmware update successful and reboot” , that means update is finished.
Frequently Asked Questions:
Q1: What is the primary advantage of the 915MHz version over 2.4GHz?
Ans: The 915MHz version generally offers better signal penetration through obstacles and longer theoretical range, making it ideal for long-range FPV and environments with signal interference.
Q2: Is this kit compatible with all flight controllers?
Ans: This kit uses the ExpressLRS protocol, which is compatible with most modern flight controllers that support serial communication (UART) for receiver input (e.g., CRSF, SBUS).
Q3: Do I need to flash custom firmware to use this kit?
Ans: Yes, you will typically need to flash ExpressLRS firmware onto both the ES900TX and ES900RX modules to match your desired version and bind them.
