25.5x25.5mm HGLRC SPECTER 15A ELRS AIO Flight Controller with 15A 4in1 ESC UARTS R1 ExpressLRS 2.4G

Introduction:

This is an F411 15A 2-4S ELRS AIO integrated brushless flight controller that integrates a UARTS serial port ExpressLRS 2.4G receiver.

The integrated UARTS serial port receiver will be more stable than the SPI receiver in terms of performance/signal.

It solves the problem of SIP receivers having few functions, cumbersome operation, and close signal distance. The integrated serial port ELRS receiver also solves the problem of no place to place the receiver during daily setup. The board has a reserved IPEX receiver seat and a T-shaped antenna, which can easily surround the harsh indoor environment flight.

The ELRS receiver has the characteristics of high sensitivity, high refresh rate and low latency, and is loved by many FPV enthusiasts. This AIO flight controller can support up to 2-4S batteries, and is also compatible with 75mm/85mm whoop/3-inch lightweight on the market.
