Big7 – 7-port MTT USB Hub For Raspberry Pi

Big7 - 7-port MTT USB Hub For Raspberry Pi blank blank

Description

The new Rev 2 version!

BIG7 is a 7-Port MTT USB hub designed for the Raspberry Pi. It extends one USB port on the Raspberry Pi to 7 usable USB ports, which allows you to connect many more USB devices to your Raspberry Pi.

Please note: Speed limited to USB 2.0 and power is limited to 3A for all ports in self-power mode, 500mA for all ports in bus-power mode. See specifications below.

The power of the USB ports can be controlled by software or an external switch (it is not Per-Port Power Switching (PPPS), please read the user manual to learn how it works).

Compatability

This USB hub is compatible with all versions of Raspberry Pi, however if you want to use BIG7 on Raspberry Pi 4, you cannot use the pogo pin to connect the D+ and D-. Instead, you need to use a mini-USB cable  to connect BIG7 to Raspberry Pi 4’s USB 2.0 port, and also move the power link jumper to the left (ou can also connect BIG7 to the USB 3.0 port, but BIG7 will still work as a USB 2.0 hub.

Size & Mounting

The board size of this USB hub is the same as a Raspberry Pi 3/4. This hub has 6 mounting holes at correct positions and could be mounted under any Raspberry Pi model except the compute module.

Backpowering Option

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. If you are using Raspberry Pi B+, 2B, 3B or 3B+, the BIG7 can make both power and USB data connection to your Raspberry Pi without using a USB cable.
