What does this board do?

Allows you to control power of a USB device connected - using a Raspberry Pi GPIO, a switch/pushbutton or a simple jumper
Allows you to momentarily disconnect power from your USB device using just a pushbutton (avoiding plugging/unplugging the cable)
This board also works as a MicroUSB-female USB adapter, allowing you to turn any MicroUSB cable into a USB extension cable in a pinch
Also works as a pin-header-to-USB-power adapter in a pinch
Allows you to disconnect USB data lines from the MicroUSB port (for now, by cutting two solder jumpers)
Has helpful green LEDs on input power, output power and control pin, too!

Technical characteristics:

Uses a FDN302P (IRLML6401 equivalent, but with 2.5V Vgs) FET controlled by a BC847 transistor to switch the power on and off (active low)
There are footprints for both pullup and pulldown resistors on the BC847 gate, allowing you to set power to either default-on or default-off
Prototyping-friendly 4-pin header, with all important points (VIN/CTRL/GND/VOUT) broken out

Very useful device, and easy ordering experience

This was exactly what I was looking for to control an external USB-powered device attached to an embedded system where the system needs to be able to restart it from time to time, prior to this it required manually unplugging the device on each restart. The ordering process was simple, good communications with the developer, and it arrived quickly and was very well packaged.
