RadioMaster ERS-GPS Telemetry Sensor - ELRS ER

The Radiomaster ERS-GPS Telemetry Sensor is a compact, plug-and-play GPS module designed for use with ExpressLRS PWM receivers via the CRSF interface. It features two selectable modes: one for precise GPS position and altitude logging—ideal when paired with ER series receivers with built-in barometers—and another for accurate ground speed readings, perfect for high-speed vehicles like planes, jets, boats, and cars. The sensor also includes a pass-through function for easy expansion of telemetry sensors through daisy-chaining. Check out all our GPS modules and our entire RadioMaster selection!
