RadioMaster ERS-CV01 is a compact cell voltage sensor designed for ExpressLRS receivers. It is primarily designed for PWM ELRS receivers used in pilotless aircraft models. The sensor connects via UART interface and communicates using the CRSF protocol. It is compatible with Radiomaster ER6, ER8, ER8G and ER8GV receivers as well as other ELRS receivers with an available UART port. Due to the UART input and output, it is possible to chain multiple sensors together.
ERS-CV01 connects to the balance connector of the battery, measuring the voltage of each cell individually. The sensor supports 2-8S Lipo batteries.
To configure the sensor and correctly display telemetry on a transmitter with EdgeTX firmware, a LUA script RadioMaster Sensor Configurator is provided, allowing parameter settings and data recording for later analysis.
