Summary
The GEPRC ELRS Nano 915M/2.4G Dual-Band Receiver is a new Dual-Band system developed from the ExpressLRS open-source project. It is designed based on Semtech’s third-generation LR1121 RF chip, supporting 150 – 960MHz (sub-GHz) and 2.4GHz bands for Dual-Band transmission.
The ELRS Nano 915M/2.4G Dual-Band Receiver features dual LR1121 chips, allowing easy switching between 915M , 2.4G when paired with 915M/2.4G antennas. It is fully compatible with existing 915M and 2.4G ELRS TX modules.
The TCXO temperature-compensated crystal oscillator ensures reliable performance across temperature variations, with telemetry power up to 100mW. The built-in WiFi antenna facilitates effortless firmware updates, and the SH1.0 connector simplifies installation.
