Frequently Asked Questions
How do I bind the ER3C-i to my ExpressLRS transmitter?
Press and hold the bind button on the receiver while powering it on. The LED will flash rapidly. In your ExpressLRS transmitter menu, select “Bind” on the corresponding module. Wait for the LED to turn solid, indicating a successful bind.
How are servos and battery voltage connected?
Connect each servo’s signal wire to CH1, CH2, or CH3 pads and power/ground to the 3-pin servo headers. Attach your battery’s positive and negative leads to the VBAT pads. The receiver auto-selects the correct voltage source and begins telemetry reporting.
What range and telemetry can I expect?
With 10mW telemetry power and ExpressLRS 3.3.0 protocol, you can achieve reliable control and real-time voltage feedback over several kilometers in open environments, making it ideal for long-range surface model applications.
