Tiny solder-down module with NXP’s i.MX93 processor
27mm SoM offers low-power 64-bit solution for intelligent edge processing
QS93 is a 27mm x 27mm QFN Style solder-down system-on-module with NXP’s dual-core i.MX935 with ARM Cortex-A55 processors, plus RAM, Flash memory and power management, integrated on a QFN-footprint PCB with excellent EMC, thermal and cost optimisations. The module is square, with a height of 2.7mm, and requires a single 3.3v supply. A full industrial operating temperature range of -40C to +85C is supported.
The QS93 module’s i.MX935 processor provides a dual 1.7GHz ARM Cortex-A55 core as well as a separate ARM Cortex-M33 running at 250MHz. There 1GB of of LPDDR4 RAM, 4GB eMMC Flash, and a wide range of interfaces including dual USB and dual Ethernet. The i.MX935 also includes an Arm® Ethos™ U-65 microNPU which affords energy-efficient implementation of machine learning (ML) tasks.
As well as energy-efficient operation, the i.MX93 processor offers powerful multimedia capability, with MIPI-CSI camera, a 2D GPU and LVDS display support. Optimal security features are provided by NXP’s Edgelock Secure Enclave.
QS93 comes with a dedicated development system, equipped with Linux BSP.

QFN-Style SoM Advantages
For larger volume applications, or where a tiny footprint is needed, Ka-Ro QFN solder-down modules fit the bill perfectly.
In addition they offer:
Guaranteed Longevity
Longevity is a major issue for ARM-based system-on-modules, as they don’t conform to any industry-standard pinout. Since the first system-on-module shipped in 2002, we have guaranteed the lifetime of our products. For our NXP and ST Micro based products longevity guarantees are underwritten by the vendor, with 10 year lifetime guaranteed, with an expectation of 15 years from launch.
Because Ka-Ro modules are manufactured in a high-quality small-batch production facility in Ka-Ro’s own factory in Aachen Germany, there are never problems with manufacturing standards or with supply. If you order 100 modules and we don’t have them in stock, we will make them. Often, modules are produced in large batches by volume-oriented contract manufacturers in the Far East, and once they are gone, they are gone, until orders for at least 5,000 accumulate in order to justify a run.
Our BSPs for Yocto Linux, Debian, Windows 10 IoT Core and QNX are in most cases complete, and are designed so that you can use them without further development or modification. One of the key advantages of the system-on-module approach is rapid time-to-market, and this cannot be realised if there is an unknown amount of extra work to be done to achieve a complete production ready hardware + software platform.
QS family modules offer a high degree of pin-compatibility. It is therefore possible to design baseboards which are ready for different QS/QSX family members, so that decisions on processing power can be deferred until the application is finished and tested, without delaying completion of hardware design. Additionally, customer products may be upgraded as new, more powerful pin-compatible modules become available.
We are experts in what we do. As well as 25 years of experience in supporting hundreds of SoM design-ins, our services group develops software, including full BSPs, and complex baseboard hardware in-house. This level of knowledge means that you can be absolutely confident of success in your project, thanks to our ability to support you, and to quickly resolve any problems which may arise along the way.
