Description
This HAT includes two 2.5 Gbps Ethernet ports (Realtek 8125BG), an M.2 M-key NVMe slot (2230, 2242, 2260, 2280), and a 12V power input.
The interfaces are adapted through an ASM2806 PCIe Gen 3 switch, with 2 uplinks (the Pi 5 can only use 1), and 4 downlinks—the 4th is exposed as a Pi 5 style PCIe FPC header, so you can daisy-chain other PCIe boards on top of this one!
It has a 40 pin GPIO plug, which supplies power to the Pi, and it is not pass-through type, so you would not be able to mount another HAT on top of this board.
To use the board at Gen 3.0 speeds, after connecting it to the Pi, you need to add the following lines to /boot/firmware/config.txt:
dtparam=pciex1
dtparam=pciex1_gen=3
I am currently testing the board and will update this page with more information later.
