Like the previous members of its Compute Module family, this newest iteration is intended for industrial use and will plug in to a Compute Module I/O board (CMIO). It improves upon its immediate Compute Module 3 predecessor with the quad-core Broadcom BCM2837BO ARM SoC that can also be found on the Raspberry Pi 3B+, however, it sees its maximum clock reduced from 1.4GHz to 1.2GHz. Going head-to-head with the previous generation model, the Compute Module can withstand higher thermal loads for longer periods of time before it throttles back clock speeds.
Compared to the original Compute Module, this new entry offers a 10x uplift in performance and twice the RAM (now at 1GB). It is offered in four configurations, including a base “Lite” version that doesn’t include onboard NAND. There also configurations that give you either 8GB, 16GB, or 32GB of NAND storage.
The Compute Module 3+ is priced at $25, $30, $35, and $40 respectively for the Lite, 8GB, 16GB, and 32GB configurations. Also available will be the Compute Module 3+ Developmental Kit (pricing not yet confirmed). This kit includes a CMIO breakout board, a Compute Model 3+ Lite and 32GB Module, camera/display adapters, and a USB A to B cable.
For or those looking to purchase the new Compute Module 3+ in the United States, your only option at the moment appears to be Newark element14.
