Caddx SuperF405HD AIO ELRS V1.0

The Caddx SuperF405HD AIO ELRS V1.0 is a highly integrated flight controller designed for 2-4S digital FPV whoops, toothpicks, and micro cinewhoops. Featuring a powerful STM32F405 processor and a built-in UART-based ELRS 2.4GHz receiver, this board streamlines your build by eliminating the need for external receiver wiring and soldering. It comes equipped with a dedicated plug-and-play connector for HD video transmitters, making digital builds cleaner and much faster to assemble.
