Each package of this USB hub contains:
- 4-port USB hub board x 1
- plastic spacer x 4
- M2.5 plastic screw x 4
- M2.5 plastic nut x 4
- Ferrite ring x 1
The 4 pogo pins on the back will connect the PP1, PP6, PP22 and PP23 testing pads on Raspberry Pi Zero, hence no soldering will be needed.
The USB hub will take power directly from your Raspberry Pi Zero, so you don’t need to power the USB hub separately. However you can use the JST XH2.54 connector on board as the alternative power input port.
The blue LED on board works the power indicator, and will lights up when power is connected.
Each USB port has a dedicated white LED as transaction indicator, and a dedicated electrolytic capacitor to help stabilizing the output voltage.
If you use this USB hub with other types of computer, you can use a USB cable (not included) to connect the mini-USB port on board to the up-stream USB port.
