Hardware Interface
tip
- Designed as a board-to-board connector.
- Due to the RK3576 chip's PIN limitations, it supports only 1 HDMI and 1 DSI, whereas the Raspberry Pi CM4 supports up to 2 HDMI and 2 DSI.
- AmrSoM-CM5 has an additional PCIe and USB3 compared to the Raspberry Pi CM4.
You can use the Raspberry Pi CM4 baseboard.
