The board has a USB port directly connected to the processor. Other boards like the Naze and Flip32
|
||||
have an on-board USB to uart adapter which connect to the processor's serial port instead.
|
||||
|
||||
Currently there is no support for virtual com port functionality on the CC3D which means that cleanflight
|
||||
does not currently use the USB socket at all. Therefore, the communication with the board is achieved through a USB-UART adaptater connected to the Main port.
|

|

The board cannot currently be used for hexacopters/octocopters.

Tricopter & Airplane support is untested, please report success or failure if you try it.

To connect the GUI to the flight controller you need additional hardware attached to the USART1 serial port (by default).

To connect the GUI to the flight controller you just need a USB cable to use the Virtual Com Port (VCP).
