RadioMaster ER6 2.4GHz ELRS PWM Receiver

The RadioMaster ER6 is a 6-channel PWM receiver built on ExpressLRS, made for fixed-wing, cars, boats and anything that drives servos directly. It reports receiver or external battery voltage automatically, sends telemetry at up to 100mW, and its dual 20cm antennas and one-piece moulded shell make it tough and reliable. Wi-Fi lets you update firmware and configure it from the ExpressLRS WebUI.

Key features

• 6 PWM channel outputs on standard 2.54mm headers
• Automatic voltage telemetry – external battery or receiver voltage
• Telemetry power up to 100mW (adjustable via LUA)
• Dual 20cm high-sensitivity antennas
• Reserved 4-pin CRSF port; CRSF or SBUS serial output
• Wi-Fi firmware updates and WebUI configuration
• One-piece moulded shell for strength

Specifications

Compatibility

• For planes, cars and boats - servos and ESC plug straight in. The CRSF / SBUS port can also feed a flight controller (e.g. a wing FC) if you add one later.
• Power: 4.5-8.4V from the ESC BEC or a receiver pack.
• Radio: any ELRS 2.4GHz transmitter.
• Sensors: add RadioMaster ERS telemetry sensors on the CRSF port.

Works with (available at AeroFlow)
