Radiomaster RP4TD-M is a small receiver for ExpressLRS system on 2.4GHz. ExpressLRS is an advanced open source RC system with long range, low latency, high refresh rate and lots of useful features. Learn more about ELRS here.
The receiver has a SX1281 chip pair to provide full diversity, thanks to the SX1281. The RP4 receiver is also equipped with TCXO. The TCXO "temperature compensated crystal oscillator" ensures stable oscillator frequency and stable RC transmission even at larger temperature deviations.
The RP4TD-M receiver is a smaller variant of the classic Radiomaster RP4 receiver. However, the RP4TD-M is not equipped with an output amplifier and the telemetry power is 10mW. The receiver is thus particularly suitable for freestyle or racing drones.
