It extends one USB port on Raspberry Pi to 7 usable USB ports, which allows you to connect much more USB devices to your Raspberry Pi. There is a red LED on board as the power indicator, and seven green LEDs aside the USB ports as transaction indicators. + +This USB hub is compatible with all versions of Raspberry Pi, including the old A/B model, A+/B+ model, compute module (with development kit), Raspberry Pi 2 (B model), Raspberry Pi Zero and Raspberry Pi 3 (B model). The board size of this USB hub is the same with Raspberry Pi B+ or Raspberry Pi 2/3 (B model). The old Raspberry Pi A and B model also have the same size, except that they don’t have those rounded corners. This USB hub has 6 mounting holes at correct positions and could be mounted under any Raspberry Pi model except the compute module. + +For different models of Raspberry Pi, this USB hub uses different approaches to (optionally) back-power the Raspberry Pi, which significantly simplifies your wiring and allows you to power both the USB hub and Raspberry Pi with only one power supply. + +There are also 7 digital output pins on board, which can tell whether a USB port is in used. These output pins are in 3.3V level and can be directly connected to Raspberry Pi’s GPIO pin, or connected to an external microcontroller.
