controller designed specifically for HD VTX. This powerful controller features an AT32F435 chip for high-performance calculations and a 5V 3A BEC solution for the HD VTX. It weighs only 4.2 grams and includes a Serial ELRS 2.4G receiver, 16MB Black Box, Barometer, and Current meter. Designed for HD VTX, it removes the OSD chip AT7456E and also added support for external GPS through Betaflight 4.4.0.
