Exp connector: Designed for ESP8266 but can be used for other things. Contains 3V3 power, TX, RX and GND.
USR & DFU: If pressed and held during reset or power on this will put the board into DFU bootloader mode. When the system is up and running the button is still unused, but could be used to trigger functionality in the firmware.
SWD: Connector for programming and debugging MCU. Uses same pin-out as Crazyflie 2.0 and this adapter can be used to connect debuggers.
FTDI: Connector designed for the FTDI serial-to-USB cable (TTL-232R-3V3). Except for getting a serial console for debugging it can also be used to power the board. Note that signals are 3V3 and power is 5V.
M3 mounting holes
MCU controlled LEDs:
POWER: On when board is powered
RANGING: Blinking when ranging is in progress
