India-based Calixto Systems has unveiled the i.MX93 VERSA SO-DIMM system-on-module (SoM) powered by an NXP i.MX 93 Arm Cortex-A55/M33 SoC with Ethos-U65 micro NPU for Edge AI applications, as well as an evaluation kit (EVK).
The system-on-module features up to 2GB LPDDR4x RAM, 16GB eMMC flash, a gigabit Ethernet PHY, and exposes various I/Os through a 200-pin SO-DIMM edge connector, such as MIPI DSI, LVDS, and parallel RGB display interfaces, MIPI CSI and Parallel camera interfaces, dual GbE (on PHY on-module, one on carrier), and more. The i.MX93 VERSA module targets smart industrial automation, healthcare, retail, and connected edge systems with specific size, performance, and power efficiency requirements.

There’s nothing much about software on the product page, but the company told CNX Software they provide a Linux BSP featuring U-Boot bootloader, the Linux Kernel, and Yocto Project build system for custom Linux distributions, as well as a Debian-based filesystem. The BSP also includes reference drivers, sample applications, and documentation, and has been fully tested on the VERSA Evaluation Board shown below. The calixto-systems GitHub account may have more for the new module and board later on.
The i.MX93 VESA SOM EVB comes with a Gigabit Ethernet port, a USB 2.0 host and OTG ports, a microSD card slot, MIPI DSI and LVDS display connectors, a MIPI CSI connector, CAN Bus and RS485 interfaces, 12V DC input, 50-pin and 20-pin GPIO headers, debug serial and JTAG connectors, and an RTC with a super capacitor.
The market is already well-served with various NXP i.MX 93 system-on-modules such as Forlinx FET-MX9352-C and CompuLab UCM-iMX93 with board-to-board connectors, iWave Systems iW-RainboW-G50M and ADLINK OSM-IMX93 OSM-compliant modules, the Ronetix RNX-iMX93-SMARC following the SMARC 2.1 standard with a 313-pin MXM edge connector, and other NXP i.MX 93 SO-DIMM SoMs like the VAR-SOM-MX93.
The i.MX93 VERSA SO-DIMM system-on-module just adds to the list, and I could not find any specific selling points/differentiating features compared to competitors. It’s not the first time we have written about the company, as we covered Calixto Systems AM335x-VERSA-SOM on CNX Software back in 2012.
Pricing information has not been made public. The products page has limited additional information about the VERSA family of CPU modules.
