The RadioMaster XR1 Nano is an ultra-compact ExpressLRS receiver built around the third-generation Semtech LR1121 transceiver, with this dual-band variant switchable between 2.4GHz and 900MHz without swapping antennas.

Key features

Semtech LR1121 transceiver paired with an ESP32-C3 MCU for strong range and sensitivity on either band
Just 1.0g and 20 x 13 x 3mm, small enough for nano and micro whoop builds
Built-in WiFi WebUI for configuring settings and updating firmware without a separate app
CRSF and a secondary UART bus interface, with castellated pads for direct soldering
IPEX-1 antenna connector; ships with a T-antenna, CRSF wire, heat-shrink and a manual card
Supports ExpressLRS packet rates up to 1000Hz, with a 50Hz minimum refresh rate
