Overview

RadioMaster ERS-GPS is a plug-and-play GPS Sensor designed for use with compatible ExpressLRS PWM receivers. It connects via the CRSF telemetry interface and provides two operating modes: GPS Data mode for position/altitude logging, and GPS Ground Speed mode for real-time speed tracking (including peak speed).

The ERS-GPS also includes an in/out pass-through port for daisy-chaining additional telemetry sensors for future expansion.

Key Features

  • Two modes: GPS Data mode and GPS Ground Speed mode
  • Speed tracking: real-time speed and peak speed delivered to the radio
  • Pass-through telemetry port: supports daisy-chain sensor expansion
  • Seamless integration: built for compatible ER series ExpressLRS PWM receivers
  • Easy updates: supports updates with the RadioMaster UART tool (sold separately)
