RadioMaster ER8G 2.4ghz PWM ExpressLRS 8 Channel Receiver

Experience the power and reliability of ExpressLRS in a compact PWM format with the RadioMaster ER8G receiver! Designed for RC pilots who need direct servo control, this receiver provides 8 standard PWM output channels built upon the advanced ExpressLRS (ELRS) 2.4GHz protocol. Enjoy the benefits of long-range capability, low latency, and a robust connection for your aircraft.

The ER8G is an excellent choice for fixed-wing planes, gliders, or any model where you prefer direct servo connections without necessarily needing a full flight controller. It simplifies your setup while delivering top-tier performance. Get crucial flight information with built-in flight battery voltage telemetry (supporting DC 4.0 – 35V input), allowing you to monitor your power status directly from your compatible ELRS transmitter.

This receiver doesn’t just stop at PWM; it also offers CRSF and SBUS serial output options for added flexibility if you decide to connect to a flight controller later. With telemetry power up to 100mW (adjustable via LUA script) and a high-sensitivity antenna, you get a solid data link back alongside precise control. Its slim and lightweight design (12g, 60mm long) makes it easy to integrate into various builds.

If you’re searching for a dependable 8-channel ELRS PWM receiver with voltage telemetry and a compact form factor, the RadioMaster ER8G is a fantastic option.
