Radio and installation compatibility
Verify the number of PWM channels and the actual receiver variant (for example ER6G versus ER6GV). Check the radio module's ExpressLRS band, firmware and telemetry requirements before binding. PWM outputs and serial CRSF are distinct interfaces.
Install antennas away from carbon shielding and high-current wiring. Perform a safe bind, telemetry and failsafe test before relying on the link in operation.
Before ordering this receiver
- Confirm the exact model, RF band and hardware revision.
- Match ExpressLRS firmware and the radio module configuration.
- Check whether PWM, CRSF or a dedicated gimbal connection is required.
- Confirm package antenna type, plug and mounting clearance.
