RadioMaster ERS-GPS – Precision GPS Sensor for compatible ExpressLRS PWM receivers

The RadioMaster ERS-GPS is a high-performance telemetry GPS sensor designed for seamless integration with compatible ExpressLRS PWM receivers. Built for precision and ease of use, this compact GPS unit connects via the CRSF protocol and supports plug-and-play installation for quick deployment.

The RadioMaster ERS-GPS features two selectable modes: Mode 1 provides accurate GPS position and altitude data—perfect for fixed-wing aircraft and drones equipped with ER series receivers that have built-in barometers. Mode 2 focuses on real-time ground speed monitoring, making it ideal for airplanes, jets, RC boats, and surface vehicles. Whether you’re logging coordinates or analyzing top speed, this sensor offers dependable data on demand.

Future expansion is easy with the built-in telemetry pass-through port, enabling daisy-chaining of additional sensors without replacing or upgrading existing equipment. Compact and efficient, the RadioMaster ERS-GPS is the smart choice for telemetry-conscious pilots and RC hobbyists.
