This is a 4-port USB hub for Raspberry Pi A+/3A+, and it can be attached underneath. After attaching this USB hub to your Raspberry Pi A+/3A+, it immediately has 4 USB ports that could transfer data in USB 2.0 high-speed. The 4 included pogo pins will connect the testing pads on Raspberry Pi A+/3A+, hence no soldering will be needed.
Ace4U can back-power your Raspberry Pi A+/3A+, or take power from your Raspberry Pi A+/3A+ if you don’t like back-powering. You only need one 5V DC power supply to power them together. The power supply can be connected to the power micro USB port, or the XH2.54 connector on board.
The orange LED on board works the power indicator, and will lights up when power supply is connected.
Each USB port has a dedicated white LED as activity 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 micro-USB port (USB in) on board to the up-stream USB port on the computer.
You can also get an Acrylic case for it.
