Description
This HAT includes two 2.5 Gbps Ethernet ports (Realtek 8125BG), an M.2 M-key NVMe slot (2230, 2242, 2260, 2280), an additional PCIe FPC connector (to stack an additional PCIe HAT on top) 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.
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 requiring GPIO on top of this board.
You must manually enable the external PCIe connector to get this HAT to work on the Pi 5. Also, if you want Gen 3.0 speeds, also add that setting in /boot/firmware/config.txt and reboot:
dtparam=pciex1
dtparam=pciex1_gen=3
Because this HAT is not ‘HAT+’ compatible, if you want to boot from PCIe, you must also edit the Raspberry Pi EEPROM (sudo rpi-eeprom-config -e) and add the following line:
PCIE_PROBE=1
I am currently testing the board and will update this page with more information later.
