User Guide

Expected Result

Take Raspberry Pi 4B as an example:

• Insert the module to 40PIN GPIO of Raspberry Pi 4B. Connect the USB interface of USB 3.2 Gen1 HUB HAT to Raspberry PI via the USB 3.0 Adapter.
• Connect the 5V power supply to the POWER ONLY port.
• Connect USB devices to USB1-UBS4, the corresponding LED (USB1-USB4) will light up in sequence, which means the device works normally.

Working with Raspberry Pi

1. Hardware preparation

• Raspberry Pi 4B x 1
• USB 3.2 Gen1 HUB HAT x 1
• USB 3.0 Adapter x 1 (or USB3.0 cable)
• USB 3.0 SSD x 1

2.Configure Rasberry Pi

• Enter the root directory of Pi:

cd ../..

• Enter the directory of USB3.0 SSD.

cd media/pi/xxx (xxx is the name of the disk)

• Free Memory.

sudo sh -c "sync && echo 3 > /proc/sys/vm/drop_caches"

• Copy 2G data to the SSD disk.

dd if=/dev/zero of=./test_write count=2000 bs=1024k

• Copy 2G data to the Raspberry Pi.

dd if=./test_write of=/dev/null count=2000 bs=1024k 

3.Working with Ubuntu (Raspberry Pi)

• Search disk in menu -> Enter -> Open the disk.

• Choose the correct disk and click the Benchmark Partition option in the Menu:

• Click Start Benchmark, check to Perform write-benchmark, and keep other default settings.

• Input the user password and authorization.

• Test

Use with Sunrise X3 PI

• Use the USB cable to connect the USB 3.0 port of the X3 PI to the USB port of the HUB.
• Insert a USB 3.0 solid-state drive.
• Test Disk Speed Using Commands.

sudo apt-get update
sudo apt-get install hdpram -y
sudo hdpram -tT /dev/sda*

Working in Windows PC

1.Connect the USB port to USB3.0 of the PC, and you can copy the file to SSD

• Copy the file to the PC.

• Copy the file to the portable SSD.

2.Connect the USB to USB3.0 Port and connect four phones at the same time

FAQ

Question:The Mouse or Keyboard connected cannot work?

 Answer:

• Re-plug the USB cable, and make sure that the connection is normal.
• Maybe the USb3.0 adapter is broken, please change to another adapter or USB 3.0 cable for a try.

Question:How to power USB 3.2 Gen1 HUB HAT?

 Answer:

After connecting the HUB and Raspberry Pi with a USB adapter, the Raspberry Pi can supply power to the HUB; if high-power devices such as mobile hard drives are connected, an external DC 5V power supply needs to be supplied to the Type-C interface of the HUB.

Question:What is the maximum rate of the 4 USB?

 Answer:

The maximum rate of the 4 USB is 5Gbps in total.

Question:How to verify USB 3.0 hard flash driver's speed and stability on Raspberry Pi?

 Answer:

You can verify it by the following commands:

ls /dev/sd*
while true; do sudo hdparm -t /dev/sda2;  sleep 10; done

{{{5}}}

Question:When the Pi powers down via Cron will the SSD's remain powered or does the hat power then down?

 Answer:

USB power off can be done using a third-party tool (uhubctl): Linux

{{{5}}}

Question:Can I stack 2 USB 3.2 Gen1 HUB HAT and use them with a separate USB a to USB a plug (one for each unit)?

 Answer:

Theoretically, it is possible, but it is not recommended as the speed may not be sufficient and an additional power supply may be required.
