Raspberry Pi Expands Its Backwards-Suitable Compute Module 4S Household, Provides Extra RAM

Raspberry Pi has introduced new variants of the Compute Module 4S, designed for backwards compatibility with service boards designed for the sooner Compute Module 3/3+ — providing as much as eight instances the RAM of the unique fashions.

“Since 2014, we’ve offered the ability of Raspberry Pi in a versatile type issue designed particularly for industrial and embedded purposes, and we have been stunned and delighted to see the unimaginable number of methods during which our clients use Raspberry Pi Compute Modules,” Raspberry Pi’s Dave Lee writes.

“Compute Module 4S relies on the Raspberry Pi 4 structure. We designed it for industrial clients who’re migrating from Compute Module 3 or Compute Module 3+, and who want to retain the identical type issue however would love higher computing energy and extra reminiscence.”

Beforehand, the Compute Module 4S — which makes use of the SODIMM computer-on-module type issue of the sooner Compute Module 3/3+, fairly than the mezzanine board format of the mainstream Compute Module 4 household — was out there with solely 1GB of RAM, that means these upgrading from earlier modules would obtain improved CPU efficiency however no extra reminiscence. Now, three new variants have been introduced — matching the reminiscence capacities out there in the principle Compute Module 4 and Raspberry Pi 4 Mannequin B households: 2GB, 4GB, and 8GB.

“We’ll preserve Compute Module 4S in manufacturing till no less than January 2034,” Lee guarantees, “and we’ve produced a transition doc specifically to assist customers migrate to it from Compute Module 1, Compute Module 3, or Compute Module 3+. Compute Module 4S boards are in inventory and out there now from our Accepted Resellers for business, with a most lead time of six weeks. These modules are equipped solely in bulk 200-unit packing containers, with costs per unit ranging from $25 US.”

These concerned about selecting up a few hundred modules, in both the eMMC-equipped 4S or eMMC-free 4S Lite flavors, are suggested to get in contact with a Raspberry Pi Accepted Reseller by means of the corporate’s web site.
