Sentinel Core – A Raspberry Pi CM5 mini-ITX carrier board with a PCIe x16 slot (Crowdfunding)

Sanctuary Systems’ Sentinel Core is a Raspberry Pi CM5 mini-ITX carrier board with a PCIe x16 slot to easily connect a graphics card to accelerate 3D graphics, video transcoding, or AI workloads.

It’s basically a larger Raspberry Pi CM5 IO board with a prototyping area, a PCIe slot, and a 24-pin ATX power connector. The Sentinel Core also comes with two HDMI ports, a Gigabit Ethernet port, two USB 3.0 ports, MIPI DSI/CSI connectors, and the usual 40-pin GPIO header.
