Introduction
This is a Raspberry Pi driver-free 4-way USB 3.2 Gen1 expansion board, which can expand a USB port on the Raspberry Pi to 4 available USB ports, so that your Raspberry Pi can connect to more USB devices.
Based on the Raspberry Pi 40PIN interface design, it is tailored for the Raspberry Pi 4th generation. It adopts the USB 3.2 Gen1 standard and can provide a transmission speed of up to 5 Gbps, which is 10 times faster than USB 2.0.
onboard resources
1. Raspberry Pi GPIO interface: easy to connect to Raspberry Pi
2. USB 3.2 Gen1 HUB interface: Connect to the USB interface of Raspberry Pi
3. USB 3.2 Gen1 expansion interface: USB1~USB4 total 4 expansion interfaces
4. PWR ONLY power supply interface: external 5V DC power supply
5. VL817-Q7: USB HUB chip
6. MX25L512COI-10G: FLASH chip
7. PWR: power indicator light
8. USB1~USB4: Indicate the working status of each USB interface
features
Onboard 4 USB 3.2 Gen1 expansion ports, compatible with USB 3.0 / 2.0 /1.1 transmission
The onboard external Micro USB 5V DC power supply interface ensures a more stable power supply
There is 1 power indicator light and 4 USB extension interface status indicators on board, which is convenient for viewing the working status
Driver-free, plug and play, compatible with Windows, mac OS, Linux and Android systems
Specially built for Raspberry Pi 4, also suitable for other motherboards of Raspberry Pi
Provide complete supporting information manuals
Industrial-grade USB HUB 4-port multi-interface hub
Product Features
Onboard 4-way USB expansion port, compatible with USB 2.0/1.1 transmission
4-way high-speed USB, the maximum speed is 480Mbps
Using industrial-grade HUB chips, using MTT technology, 4-way USB is more stable and smooth when used at the same time
Each USB port is ESD protected, protecting device connections from power surge damage and data loss
The on-board overvoltage protection circuit can effectively prevent other high-voltage power sources from causing equipment damage
Onboard multiple protection circuits: overvoltage protection, overcurrent and short circuit protection, overtemperature protection, current protection, undervoltage lockout, 8KV ESD protection, filter protection, etc.
There are multiple LED indicators on the board, which is convenient to check the working status of the power supply and USB interface
Industrial-grade metal shell, sturdy and durable, screw holes for easy installation and fixing
hardware connection
The power supply only allows 5V power supply. If the voltage is too high, the internal protection will cut off the power supply directly.
4 USB output ports, the maximum output current is 1.2A, exceeding this upper limit will trigger short-circuit protection, and the device needs to be removed to recover
Working temperature range: -40 ℃ ~ 85 ℃, no condensation, this module is not waterproof
LED1~LED4 indicate the enumeration status of each USB, if a USB device is connected and the enumeration is successful, the LED lights up
The red PWR light indicates power supply
PCI-E 4 USB Adapter Multiplier Card
* Plug and Play
* PCI-E Splitter 1 to 4 PCI Riser Card for PCIe 1 to 4 PCI-Express 16X Slots Riser Card,
* Supported system Windows10/8/7 (32/64 bit)/ XP; Linux
