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.

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.

NXP i.MX 93 development boardThe 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.

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…
