New connectors 
The new connectors on the underside of the Raspberry Pi CM4 are designed to help you make the Raspberry Pi the heart of your embedded project.
32 variants - A Choice of Ram and eMMC Flash Memory
With four RAM options, four Flash options, and optional wireless connectivity, There are a total of 32 variants, with prices ranging from $25 (for the 1GB RAM, Lite, no wireless variant) to $90 (for the 8GB RAM, 32GB Flash, wireless variant). The 1GB RAM and no wireless variants keep the same price points ($25, $30, $35, and $40) as their Compute Module 3+ equivalents: once again, they have managed to pack a lot more performance into the platform without increasing the price.
