11.3 USB3.0
PiGear Nano comes with 8 USB 3.0 ports, and each of them has its own activitiy indicator (green
LED) near the VL817 chips.
Limited by Raspberry Pi CM4‟s PCI Express Gen 2 lane, these 8 USB 3.0 ports share a total of
4Gbps of data bandwidth. However, there are scenarios that need to connect multiple USB 3.0
devices at the same time, while they don‟t have to work simultaneously. Providing 8 USB 3.0 ports
indeed unlock many possibilities and offers more flexibility.
Four stacked USB connectors are used and each of them has a dedicated 1A current limiter
(SY6280AAAC configured as 1A limiter), which means every two stacked USB ports can output up to
1A current (given the power supply can offer that current).
If you will use multiple USB devices or there will be a lot of data transation via USB bus, it is
recommended to put the small heatsink (included in the package) on the VL805 chip (on the back of
the board).
