CompuLab UCM-iMX8M-Mini is a Stamp Size i.MX 8M Mini SoM

We’ve recently written about several new hardware platforms based on the latest NXP i.MX 8M Mini processor family including Nitrogen8M_Mini SBC and F&S Elektronik PicoCore MX8MM SoM. Thanks to a new 14-nm process, the new family has the advantage of consuming less power, and the Cortex-A53 cores can run at a higher frequency. They should cost less as well thanks to cost-saving measures like the adoption of a 1080p video decoder instead of a 4K decoder found in the older NXP i.MX 8M family.

CompuLab has now launched their own NXP i.MX 8M Mini SoM with UCM-iMX8M-Mini module that’s about the size of a largish stamp (38 x 28 mm) suitable for portable and space constrained applications such as professional handheld devices, wearable healthcare monitors and medical devices, autonomous drones with visual object recognition, or portable instrumentation equipment with advanced HMI.
