Overview
|
- Raspberry Pi Compute Module 4 SODIMM (CM4S) is a System on Module (SoM) containing processor, memory, eMMC flash, and supporting power circuitry. These modules allow a designer to leverage the Raspberry Pi hardware and software stack in their own custom systems and form factors. The SODIMM form factor compute modules have 18 additional GPIO pins compared to the standard Raspberry Pi boards, for a total of 46, opening up more options for designers. - CM4S is loosely based on Raspberry Pi 4 Model B, and for cost-sensitive applications it can be supplied without the eMMC fitted; this version is called Raspberry Pi Compute Module 4 SODIMM Lite (CM4SLite). - CM4S is in the same form factor as the older Raspberry Pi Compute Module 3 and 3+, which are mechanically compatible with DDR2-SODIMM. - This device is intended for specific industrial customers migrating from Compute Module 3 or Compute Module 3+ and is not for general sale. For new customers who are designing products, we recommend using Raspberry Pi Compute Module 4. |
