VisionSOM-iMX91

VisionSOM-iMX91

VisionSOM-iMX91 is comprised of a small and energy efficient processor module with CPU interfaces accessibility, integrated Machine-Learning + Artificial Intelligence NPU coprocessor and standard I/O functionality, insluding modern I3C serial interface. It is an ideal solution for modern IoT embedded projects and intelligent edge devices. VisionSOM-iMX91 can trim 8-12 months from design cycle and can be easy adapted to existing projects or can be used together with a dedicated carrier board. Customers who are looking for a complete solution can use a set comprised of System on Module (SoM) and Carrier Board (CB). VisionSOM-iMX91 requires a matching customer’s board or a carrier board to establish a complete system. Carrier Board together with VisionSOM-iMX91 is a ready to use computer on board and is giving enormous flexibility in building projects.
