3.13 USB Interface

The development board has a Micro-USB Type-AB connector that features a Full-Speed USB 2.1 which supports USB Host and Device mode.

In case to use the USB as Host mode, to provide power to USB device, power the development board using the Extension Power Header by means of the VCC_EXT_P5V0 pin (pin 1 of J201) and pull down the PD11 GPIO (VBUS_EN) to enable the power switch MIC2005A, U200. Consider that the VBUS0 voltage suffers from the voltage dropout of the diodes, D200 and D206.
