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 chip. 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!
Bullet Point Improved PCB design is better for heat dissipation. Upgraded rigid antenna with greater durability and performance. LED on the top side of PCB. Solder pads are improved and easier to solder to.
Specification Item: RP1 Nano ExpressLRS 2.4ghz Receiver Type: ISM Antenna: 65mm 2.4ghz T Antenna Maximum receive refresh rate: 500Hz / F1000Hz Minimum receiver refresh rate: 25Hz Working voltage: 5v Weight: 2.2g (Including antenna) Dimension: 13mm*11mm*3mm Firmware Version: ExpressLRS v2.4 pre-installed FW Target: RadioMaster RP1/2 2400 RX Bus interface: CRSF
The RadioMaster RP series of receivers are designed with size, ease of use and range in mind. Utilizing ExpressLRS 2.4ghz Open-source firmware the RP series of nano receivers deliver features and range today pilots have come to expect.
Developed around the ESP8285 MCU and SX1280IMLTRT RF Chip the RP series offer Lora and FLRC 2.4ghz RF links offering incredible range and low latency. With Wifi built in FW updates can be done on your craft without the need to remove the receiver. Binding can be done using a bind phrase meaning no more bind plugs or fiddly button presses while trying to plug in your battery.
The RP3 receiver features a Skyworks SE2431L providing an LNA for improved receiver performance, a PA providing up to 250mw of telemetry performance and antenna switching for antenna diversity.
