Coming Soon: An ideal solution for low-end and price-sensitive devices based on the NXP i.MX91 processor.
The VAR-SOM-MX91 System on Module runs on a 1.4GHz Cortex™-A55 NXP iMX91 processor and provides energy-flex architecture, built-in security along with industrial temperature grade and integrated connectivity options such as dual CAN-FD, dual GbE and certified dual-band Wi-Fi 802.11 ax/ac/a/b/g/n with optional 802.15.4 and BT/BLE 5.4.
The VAR-SOM-MX91 SoM is compatible with the VAR-SOM Pin2Pin family, providing maximum scalability and leading-edge capabilities; from entry-level i.MX6UL/6ULL platforms, through i.MX 8M NANO/MINI/PLUS, i.MX 93 and AM62x, up to i.MX 8X and 8QuadMax high-performance platforms.
For the complete Pin2Pin product list, check out Variscite’s Pin2Pin System on Module product families.
* The Pin2Pin compatibility depends on pinmux options; please verify the detailed pinout table in the related SoM to confirm compatibility is maintained in your specific design.
** Variscite’s i.MX 91 System on Module (SoM) is in development at this stage. The information on this page is subject to change without notice. For additional information contact us.
