VAR-SOM-MX93 SO-DIMM NXP i.MX 93 SoM features WiFi, Bluetooth, Audio codec

Variscite VAR-SOM-MX93 is a 200-pin SO-DIMM system-on-module based on NXP i.MX 93 dual-core Cortex-A55/M33 AI processor with up to 2 GB LPDDR4 RAM, 64GB eMMC flash, and onboard WiFi & Bluetooth module and audio driver.

The Variscite module follows the announcement of two other NXP i.MX 93 system-on-modules, namely the Forlinx FET-MX9352-C with board-to-board connectors and the iWave Systems iW-RainboW-G50M LGA module compliant with OSM Size L form factor to be soldered directly on the carrier board.

VAR-SOM-MX93 specifications:

      • Extended: -25 to 85°C
      • Industrial: -40 to 85°C
    • Storage: -40 to 85°C
  • Humidity – 5% to 95%

The new module is pin-to-pin compatible with earlier “VAR-SOM Pin2Pin” modules based on NXP i.MX 6 or i.MX 8 processors. Variscite provides Linux support with Yocto, Debian, and Boot2Qt for the Cortex-A55 core(s), and FreeRTOS for the Cortex-M33 real-time core. You should eventually find more details about the software in the wiki, but it’s currently under construction with very limited information.

The company also offers the VAR-SOM-MX93 Evaluation kit based on the Symphony carrier board with an LVDS interface, capacitive and resistive touch panel interfaces, dual Gigabit Ethernet, two audio jacks, on-board digital microphone, CAN Bus, microSD card socket, and so on. A 7-inch WVGA display with a capacitive touchscreen is available as an option.

Variscite did not provide pricing information for the SoM and the development kit but like other NXP i.MX 93 system-on-modules, the VAR-SOM-MX93 SO-DIMM module will be available for at least 15 years, that is to say until 2038. More details may be found on the product page.

  1. Now for a DDR2-SODIMM version of Waveshare’s CM4 to RPi3B+ and RPi4B converter carrier boards so we can use these VAR-SOM Pin2Pin modules in RPi SBC cases…
