Matek ELRS 2.4G PWM Vario RX is a 6 channel PWM receiver with integrated vario and antenna diversity. It can be used especially on gliders and other aircraft models where long range is required. The receiver also serves as a voltage sensor for the main battery. Information from the vario, battery voltage and transmission quality are transmitted via telemetry with output power up to 180mW (22.5dBm).
