Mini Base Board (A) for Raspberry Pi CM5
The Waveshare Mini Base Board (A) is an expansion board for the Raspberry Pi Compute Module 5 (CM5) that offers a range of features packed onto a compact carrier, allowing extensive prototyping or general breakout usage of your CM5.
Key features include 2x USB 3.2 Gen1 ports, a full-size HDMI port, a second HDMI port via FFC, Gigabit Ethernet, RTC battery holder and PCI-e interface. MIPI DSI and CSI connectors enable display and camera integration, while the MicroSD card slot provides flexible storage/boot options.
Power is supplied via USB-C (we recommend the Raspberry Pi 27W PSU), with a fan header for cooling and mounting holes for installation.
Compute Module 5 not included.
