One can never have enough socks, or USB ports. Add some more USB capability to your Raspberry Pi Zero with the Zero4U!
This is a 4-port USB hub for Raspberry Pi Zero, and it can be mounted back-to-back onto a Pi Zero. The 4 pogo pins on the back will connect the PP1, PP6, PP22 and PP23 testing pads on your Raspberry Pi Zero – no soldering required!
This item can only work with the Zero W if a ferrite ring is installed!
The USB hub will take power directly from your 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 an alternative power input port. The blue onboard LED is the power indicator, and will light up when power is connected. Each USB port uses a dedicated white LED as a transaction indicator, and a dedicated electrolytic capacitor to help stabilize the output voltage.
If you use this USB hub with other types of computers, you can use a USB cable (not included) to connect the onboard mini-USB port to the up-stream USB port.
Kit includes:
- 4-port USB hub board x 1
- Plastic spacer x 4
- M2.5 plastic screw x 4
- M2.5 plastic nut x 4
Note: This version of Zero4U only works with the Raspberry Pi Zero v1.3 (with camera connector).
Note: As of 3/29/2017, this ships with a small Ferrite ring in each Zero4U package, in order to support the newly released Raspberry Pi Zero W. The user can put that Ferrite ring on the pogo pins to avoid the interference from the on-board antenna.
Jargon buster
Plain-language definitions for the technical terms used above.
- electrolytic capacitor
- An electrolytic capacitor is a type of capacitor that can store relatively large amounts of electrical charge in a small package. It is commonly used for smoothing power supplies, reducing noise, and short-term energy storage, but it usually has polarity so it must be installed the correct way around.
- LED
- A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
- M2.5
- A metric screw thread size with a 2.5 mm nominal diameter. It matters for mounting because screws, standoffs, and holes must use the same size to fit securely without damaging the board.
