The ERS-GPS Telemetry Sensor is a specialized GPS unit designed by Radiomaster for use with compatible ExpressLRS PWM receivers. This plug-and-play sensor integrates with the receiver via the CRSF interface.  

Equipped with two modes— Mode one to provide accurate GPS data and Mode two to provide accurate ground speed. Mode one is ideal capturing position and altitude logs when used with our ER series receivers with built-in barometers. Mode two is ideal for measuring speed in airplanes, jets, boats, or cars. Additionally, the ERS-GPS features a pass-through function that allows for easy future expansion of telemetry sensors through a daisy-chain arrangement.
