This is a Radiomaster RP1 ExpressLRS Nano Receiver.

The RP1 and RP2 2.4GHz ELRS nano series receivers are open-source receivers based on ExpressLRS.

The Nano receivers, first developed by Jye Smith from the ExpressLRS development team, feature ESP8285 MCU and SX1280 RF chips. The RP1 has a UFL antenna socket for full-range antenna use. The RP2 has a built-in ceramic antenna which is super light and small in size and ideal for racing.

The RP1 and RP2 feature WIFI built in so you can upgrade firmware by WIFI and configure the Receiver via the built-in WebUI with your PC or mobile phone.

Due to the low-latency and high-refresh-rate RF module, the RP1 and RP2 are ideal for FPV races or Long Range. Suitable for Whoops, drones, and fixed-wing models due to the ultra-light and Nano size, these receivers can fit just about anywhere.
