<p>The RadioMaster RP series receivers are built-in a TCXO (temperature-compensated crystal oscillator) now, which ensures reliable, stable, and accurate signal reception, allowing for superior performance in demanding environments and enhancing the flight experience.</p><p><br></p><p>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.</p><p><br></p><p>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.</p><p><br></p><p>Due to the low-latency and high-refresh-rate RF module, the RP1 and RP2 are ideal for FPV races or Long Range. &nbsp;Suitable for many models due to the ultra-light and Nano size, these receivers can fit just about anywhere!</p><h4><b><br></b></h4><h4><b><br></b></h4><h4>Features</h4><h4><br></h4><ul><li><p><span style="font-weight: normal;">Improved PCB design is better for heat dissipation.</span></p></li></ul><ul><li><p><span style="font-weight: normal;">LED on the top side of PCB.</span></p></li></ul><ul><li><p><span style="font-weight: normal;">Solder pads are improved and easier to solder to.</span></p></li></ul><h4></h4><ul><li><p><span style="font-weight: normal;">Built-in a TCXO (temperature compensated crystal oscillator)</span><br>Serial RX / CRSF</p></li></ul><p><br></p><p><br></p><p><br></p><p><br></p>
