6.4 USB_OTG1

USB On-The-Go, often abbreviated USB OTG, is a specification that allows USB devices such as
digital audio players or mobile phones to act as a host allowing a USB flash drive, mouse, or
keyboard to be attached and also connecting USB peripherals directly for communication purposes
among them.

Note DFU bootloader uses the USB_OTG1 port, and a "USB micro-A" cable is required. This is the
port used to program the board via Arduino IDE.

Note that the USB-OTG ESD protection ICs are not placed by default. However, there are pads
provided for such protection.
