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.

The SoftSerial port is not available when RX_PARALLEL_PWM is used. The transmission data rate is limited to 19200 baud.
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).

The entire flash ram on the target processor is flashed with a single image.
The image can be flashed by using a USB to UART adapter connected to the main port when the CC3D is put into the STM32 bootloader mode, achieved by powering on the CC3D with the SBL/3.3v pads bridged.

The OpenPilot bootloader code also allows the remaining section of flash to be reconfigured and re-flashed by the
OpenPilot Ground Station (GCS) via USB without requiring a USB to uart adapter.
In this mode a USB to uart adapter is still required to connect to via the GUI or CLI.
