Waveshare Compact PCIe With Four USB 3.2 Gen. 1 Ports for RPi CM4
If you have been using Raspberry Pi Compute Module 4, then this peripheral IO board will come in handy for many applications. With this new option for your peripheral connectivity to Raspberry Pi Computer Module 4, Waveshare’s Compact PCIe features four USB 3.2 Gen. 1 ports on the board.
There have been several IO boards for Raspberry Pi CM4 of which Jeff Geerling has posted a list of boards. This will help you choose the correct board for your application. Going back to the newly launched Waveshare’s Compact PCIe IO board, it comes with compatibility to USB 3.0/ 2.0/ 1.1. This becomes important because the design of Raspberry Pi Computer Module 4 has no USB 3.0 connectivity. However, with the exposed PCIe, the developers and makers can build their own IO boards and use them as they wish.
Features of the Waveshare Compact PCIe Board
- USB Ports: 4 USB 3.2 Gen 1 ports
- USB Compatibility: USB 3.0/ 2.0/ 1.1
- Onboard chip: VL805 chip
- Power supply: Powered by either PCIe 12V or from 12V DC header
- Dimensions: 82 mm x 39 mm
The onboard VL805 chip is very famous as a super speed USB 3.0 host controller for many USB converter boards and IO hardware. If you are looking for fewer USB ports with ethernet onboard, then Seeed Studio’s dual gigabit ethernet NICs carrier board can serve the purpose. However, for more USB ports and an easy interface, the Waveshare Compact PCIe board can become a good option at just $17.99.
With the onboard chip, the software compatibility comes easy since the VL805 chip is not new to the Raspberry Pi world. Raspberry Pi 4 single-board computer features the VL805 that is set to power save with the new firmware released in 2019. The board is set to connect horizontally rather than vertically like all other IO boards.
