Frequently Asked Questions:
Q1: What is ExpressLRS and why is it beneficial?
Ans: ExpressLRS is an open-source radio control link known for its ultra-low latency, long range, and high reliability, offering superior control performance for RC models.
Q2: How do I bind the RADIOMASTER ER4 ExpressLRS Module to my transmitter?
Ans: Upon first power-up, the ER4 enters bind mode (double LED blink). You can then use your ExpressLRS compatible radio's LUA script to bind. Alternatively, power cycle the receiver three times to enter bind mode, or hold the boot button for 10 seconds to reset it to bind mode.
Q3: Can I update the firmware on the ER4 module, and how?
Ans: Yes, the ER4 module supports Wi-Fi updates. You can connect to the receiver's Wi-Fi hotspot and access the WEBUI (10.0.0.1) in your browser to update firmware and configure settings.
