After the release of the Raspberry Pi AI Kit, we tested four PIPs: X1001, X1004, X1011, and M901. X1001, X1004, X1005 and M901 etc. all support the hailo-8 ai ​​accelerator, but X1011 does not.

It should be noted that X1004 and X1005 uses ASMedia ASM1182e PCIe switch, it can't support PCIe Gen 3 speed, so even though we forced to enable PCIe Gen 3.0 setting in Raspberry Pi 5, it is limited by ASMedia ASM1182e PCIe switch, and speed is still PCIe Gen 2.0 5Gbps speed. when you use an hailo-8 ai accelerator, Raspberry Pi Fundation highly recommends using PCIe 3.0 to achieve best performance with your AI Kit.

Our tentative conclusions are as follows:

• If you need to use hailo-8 ai accelerator with high performance, it is recommended to use X1015/X1002/X1003/M901/ the official M.2 HAT+ etc. When choosing these PIP boards, you should focus on whether there is a conflict between the camera cable and the PIP board installation, and enable PCIe3.0 to use hailo-8 ai accelerator. At the same time, you need to prepare an SD card as the system disk.
• If you don't care about the high performance brought by PCIe 3.0, then you can consider using X1004, so that you can use any socket of X1004 to install NVME SSD as the system disk, and another socket to install hailo-8 ai accelerator, so as to have both.
