Bullet Point

• Updated the F411 chip to F405, this new 20A AIO board handles a continuous current of 20A and a burst current of 22A, bringing pilots a more stable flight. 
• BETAFPV 12A/20A AIO flight controller reserves the same UART ports layout, UART3 for Rx, UART4 for DJI, UART6 for SmartAudio and the Spare UART1, more convenient for pilots to solder.
• Come with 2 integrated Plug & Play Ports for both digital VTX and Rx, less solder work needed, easy to install.
