Factory Reset
A factory reset can be triggered by holding the button pressed while powering up
the device (hold for at least 1s). This will restore all settings to factory default.
1.1.5
USB Connector
The board comprises an CP2102 chip for converting serial data to USB. The Virtual
COM Port (VCP) drivers
1
need to be installed on the host computer to use this
feature. In Windows, use the ‘Device Manager’
2
to see what COM-port is used.
The unit may be powered through the USB connector. Due to vibration, this is
however not recommended in flight in any type of aircraft.

JST GH
The GH connector from JST
3
is used on the Atom UAV standalone variant over the
DF-13 for its improved mechanical properties and ease of handling. It exposes a
3.3 V UART and may be used to supply power. The pinout is identical to what is
used in Pixhawk-based flight controllers:
