Radiomaster RP4 is a small receiver for the 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 pair of SX1281 chips and offer true diversity. The RP4 receiver is also complemented by TCXO. The TCXO "temperature compensated crystal oscillator" ensures a stable oscillator frequency and stable RC transmission even at larger temperature deviations. The receiver also features an amplifier that allows the RP4 to transmit telemetry up to 100mW. The receiver can be powered with a voltage range of 4.5-12V.
