Raspberry Pi Compute Module 4S

Based on the Raspberry Pi 4 Model B architecture, Compute Module 4S (CM4S) is intended for industrial customers migrating from Compute Module 3 or 3+, who wish to continue to use the SODIMM form factor or to take advantage of the increased SDRAM capacity.

The CM4S is now available in a wider range of RAM and eMMC storage configurations (see this blog post for more information) - please see the table below for a full list of Compute Module 4S variants and their ordering codes.

Please note: This product is only available to order via our business website in the carton quantities listed below.
