Sub250 ELRS Nano 2.4G Receiver

Sub250 ELRS Nano 2.4G Receiver

Product description

The Sub250 ELRS Nano Receiver is an extremely compact and powerful 2.4GHz receiver for FPV drones that offers the highest precision and maximum response speed.
Thanks to a sampling rate of up to 1000Hz, it enables lightning-fast signal transmission with minimal latency - perfect for FPV racing, freestyle and long-range flights.

With a weight of just 0.6 g and tiny dimensions of 14 × 11 × 3.1 mm, the receiver is ideal for Sub250 drones, Tinywhoops and ultra-light builds.
It is based on the ELRS (ExpressLRS) open-source project, which is known for its stability, reliability and long range.

The integrated WiFi module enables an easy firmware upgrade via the WebUI - without any cables or soldering.
The DCDC circuit ensures cool, efficient operation, while the included 2.4G Mini-T antenna provides stable signal transmission and excellent range.
