Radiomaster RP2 V2 ExpressLRS 2.4ghz Nano Receiver

RadioMaster RP2 is an open source, nano-sized receiver based on the revolutionary ExpressLRS system. It is equipped with ESP8285 microcontroller and SX1280 RF chip. The main feature of the RP2 is its built-in ceramic antenna, which makes it very light (only 0.55g) and compact, ideal for FPV racing or for models where space is limited. Thanks to built-in Wi-Fi, firmware updates and configuration of the receiver are carried out conveniently via a web interface from a PC or mobile phone. This receiver guarantees low latency and high refresh rate, which ensures stable and reliable communication even in difficult conditions.
