Raspberry Pi Compute Module 4S

Raspberry, Release

The Raspberry Pi Compute Module (CM) takes a modular approach to computing. The core components - processor, RAM, and storage (optional) - reside on a compact System-on-Chip (SoC) module. This core then connects to a separate daughterboard that provides the specific functionality needed for a project, such as USB ports, card readers, and other peripherals.

Based on the Raspberry Pi 4 Model B architecture, Compute Module 4S 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. Prices per unit starting from $25 US

The long-term support is one of the most compelling advantage of the Compute Module which is a flexible and future-proof platform for embedded computing projects. This model for instance is expected to remain in production through January 2034.

The SODIMM form factor of the Compute Module 4S is the same than Module 1, Compute Module 3, or Compute Module 3+. However, the Raspberry Pi Compute Module 4 boasts a more compact form factor for deeply embedded applications. The new version also does not include built-in Wi-Fi or Bluetooth.
