# Board - PYRODRONEF4

The PYRODRONEF4 target is new board developed by http://pirofliprc.com/

* flat bottom.(No component on the bottom)
* 6 uarts with 4 motor outputs(D-shot supported)
* uart 1 inverted for sbus(selectable) , uart 3 with inverter for frsky telemetry
* onboard 5V bec.
* direct solder pad layout for 4 IN 1 ESC or use 4 in 1 ESC Plug
* With uart RX pin layout inside the 4 IN 1 ESC plug for use ESC telemetry.
* USB -VCP

## Pinout
TX1, RX1  -> UART1  sbus pad       (RX1 Use for Sbus has inverter build in)
TX2, RX2  -> UART2  Esc Telemetry  (use for esc telemetery)
TX3, RX3  -> UART3	TEL PAD	       (use for frsky temeletery has inverter build in)
TX4, RX4  -> UART4                 (Free uart)
TX5, RX5  -> UART5	TX5			   (TX5 use for smart audio, No RX5 pinout )
TX6, RX6  -> UART5  			   (design to use crossfire rx)
