The Raspberry Pi Compute Module 4S is a SODIMM-fashion edition of the Compute Module four. It has the identical processor as the ordinary mannequin, however the form factor restricts the I/O capabilities, so it's no longer somewhat as versatile. And when it first launched in 2022, the Raspberry PI CM4S was only purchasable with 1GB of RAM.
Now Raspberry Pi has announced that the CM4S can now be purchased with 1GB, 2GB, 4GB, or 8GB of LPDDR4-3200 reminiscence onboard. but you're probably not going to locate them in outlets each time quickly – they're placed as a industrial product and sold in boxes of 200 or greater.
Raspberry Pi notes that the intention became to make issues convenient for "industrial valued clientele who are migrating from Compute Module three or Compute Module three+" options through offering a edition of the CM4 in the equal form component. however even with the new memory alternatives, there are some downsides to the form factor: it lacks a PCIe interface, Ethernet connections desirable out at 350Mbit/s, and USB capabilities top out at USB 2.0, amongst other issues.
