SECO Unveils SM-C12 SMARC 2.0 Compliant i.MX8M Module, CSM-B79 SMARC 2.0 Carrier Board

We’ve already seen several computers-on-module/systems-on-module based on NXP i.MX8/8M processors, most of which use proprietary standards, but so far we’ve covered at least on Qseven 2.1 CoM with Advantech ROM-7720 powered by i.MX 8QuadMax SoC.

SECO has now announced their SM-C12 module compliant with another SoM standard: SMARC 2.0. The system-on-module is powered by i.MX 8M dual or quad core processor, supports up to 4GB RAM, offers optional WiFi and Bluetooth connectivity, and plenty of I/Os thanks to the 314-pin MXM3 connector mandated by SMARC 2.0 specification. The module targets home automation, transportation, digital signage and vending machines, multimedia devices, and others applications requiring real-time processing and/or multimedia capabilities.

  1. I have a question with this kind of SOM. They have a standard for spread the pinout in the port, I mean, If I buy another SOM with the same chip and replace this one with the other one from other brand they will be compatible with SOM port without collision of peripherals or short circuits?

  2. @jeanz
    In theory, it’s pin-to-pin compatible so it should work. But in practice, I’ve read that you may have to tweak your carrier board a bit in case of electrical incompatibility (e.g. due to noise, etc…)

    You can also use other processors. At least, we know the SMARC EVB mentioned in that post will be compatible with SECO’s Atom x5 (Apollo Lake) and Xilinx Zynq FPGA+Arm SMARC 2.0 module.
