Tiny solder-down NXP i.MX 93 System-on-Module powers credit card-sized evaluation board

Ka-Ro Electronics’ QS93 is a tiny solder-down NXP i.MX 93 System-on-Module (SoM) running Linux and designed for edge processing. The company also offers a credit card-sized evaluation board that may remind some of the Raspberry Pi with its GPIO header and general layout, but it comes with two Fast Ethernet ports and one USB 2.0 port.

We’ve already covered several system-on-modules based on the NXP i.MX 93 Cortex-A55/M33 AI processor including some with high-density board-to-board connectors such as the Compulab UCM-IMX93 and Forlinx FET-MX9352-C, others with a SO-DIMM connector like the VAR-SOM-MX93, and finally some designed to be soldered on the carrier board such as the OSM-L compatible iW-RainboW-G50M, and the QS93 adds to the latter category in a tiny 27×27 mm form factor.

The company provides documentation to get started with the module and evaluation kit and a Yocto Linux BSP can be found on GitHub.

The QSBASE93 Evalkit is probably the best way to get with the 85x56mm credit card-sized SBC fitted with a Q93-5210 NXP i.MX 9352 soldered-down system-on-module, and exposing most of the interfaces from the module with dual 10/100M Ethernet, one USB 2.0 port, an LVDS display connector, a MIPI camera connector, a 40-pin Raspberry Pi-compatible GPIO header, and a USB Type-C port.

Ka-Ro electronics does not provide pricing information on the product page for the NXP i.MX 93 system-on-module instead inviting interested parties to request a quote. But I could notice the module is sold on ARIES Embedded for 69 Euros per unit, while Mouser and DirectInsight (UK) sells the QSBASE93 evaluation kit for $159.15 and 145 GBP respectively.

A bit higher priced than others. Is it the footprint that they think it could be sold for like 20usd more than competitors? Interesting to see

The link to ARIES is the QS93 module only – that’s why it’s “cheaper”
