RadioMaster XR2 ExpressLRS (ELRS) 2.4ghz Nano Receiver

These are a new addition to our super compact, lightweight receivers built on the awesome new ExpressLRS protocol/platform. These are a lower cost alternative to the RP2 ELRS receivers, arying much of the same capability (and a few differences). The main differences are this one is SLIGHTLY bigger than the RP2, so please check fit in any custom design. And they have a boot button in place of the boot pad of the RP2. As well as addition of a second TX/RX pad pair, allowing for additional functionality, or with reconfiguration, up to 4 PWM channels! (with some fine soldering, as the pads are quite small). The XR2 Receiver is a tiny but powerful device designed for 2.4GHz ExpressLRS, featuring an integrated tower antenna that provides excellent reception in its small size. Measuring just 16x12mm and weighing only 0.8g, it easily fits into even the tightest spaces in your build. Powered by the advanced third-generation Semtech LR1121 transceiver, the XR2 is compatible with all ELRS 2.4GHz transmitters and supports DK500Hz mode for LR1121-based systems, ensuring high reliability and quick response. Its built-in Wi-Fi module makes firmware updates and setup simple through a WebUI on your PC or mobile device. With ultra-low latency and high refresh rates, the XR2 is perfect for any project where small size, speed, and accuracy are key.
