Summary
The Raspberry PI Compute Module 4 is very powerful, and it brings the capabilities of the Raspberry PI 4 together in a compact, compact board suitable for deeply embedded applications. It integrates a quad-core ARM Cortex-A72 processor, dual video output, and a variety of other interfaces, and offers a rich selection of RAM, eMMC flash memory specifications, and wireless module specifications.
Main Features
- CPU upgrade to BCM2711, quad-core Cortex A72 64-bit processor, more powerful performance
- More memory options (1GB/2GB/4GB/8GB), suitable for large data compilation
- Faster eMMC flash memory with transfer rates up to 100 MBytes/s, 4 times faster than CM3+
- Added wireless module options, using the same WiFi and Bluetooth modules as the Pi4B, providing an onboard PCB antenna and external antenna, more suitable for industrial applications
- The B to B connector design has changed the previous generations of CM series gold finger design to enhance stability
- Add onboard Gigabit Ethernet design, support IEEE1588, suitable for network application development
- Special handle, easy to install.
- Add PCIe port expansion to flexibly add related modules

FAQ
Although the CM4 layout appears simple, it requires no specific I/O consideration.
The CM4 is likely to be used by serious users who will incorporate it as a part of a custom system and enclosure. These users will most likely want to source their own heatsinks to match their specific needs. Hence, it may not be worthwhile for RPT to design a heatsink themselves, especially for prototypes and amateur/hobbyist users, as the market may not be large enough. While a third-party may produce one, it is still uncertain if the demand is sufficient for such a product.
Looks like its meant to be set via devicetree. A custom overlay needs to be made for this or the i2c-rtc overlay needs to be altered.
It’s unfortunate that when burning the SD card, one has to choose between the two versions of Pi Zero W. As I use both types of Pi hardware, it would be more convenient to have one SD card image that I can share. Currently, I need to have two separate images and label them accordingly.
