SpeedyBee Nano 2.4GHz ELRS Receiver

The SpeedyBee Nano 2.4GHz ExpressLRS receiver delivers high-refresh-rate, low-latency control for FPV racing, freestyle, and micro builds. Built on the open-source ELRS architecture, this 2.4GHz receiver provides reliable range and signal penetration in an ultra-compact footprint that easily mounts inside tight whoop canopies or cramped 5-inch frames.

Key features
