The RP1 2.4GHz ELRS nano series receiver is an open-source receiver based on ExpressLRS software. This nano receiver, first developed by Jye Smith from the ExpressLRS development team, features an ESP8285 MCU and SX1280 RF chip.


It also has a u.FL antenna socket for full-range antenna use and built-in Wi-Fi so you can upgrade firmware wirelessly 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 is ideal for FPV races or Long Range. Due to the ultra-light and Nano size, this receiver can fit just about anywhere, so it is ideal for a range of whoops, drones, and fixed-wing models.
