Low-cost SoM with STMicro’s versatile STM32MP235
27mm solder-down SoM offers dual ARM Cortex-A35, NPU, VPU and GPU
The new QSMP-23 is a 27mm x 27mm QFN Style solder-down system-on-module with STMicro STM32MP235C processor. Dual ARM Cortex-A35 processors clocked at 1.2GHz are complemented by a 400MHz ARM Cortex-M33 MCU, a 0.6 TOPS NPU for AI/ML tasks, dual MIPI-CSI camera inputs and a powerful GPU as well as an HD 60fps video pipeline. The QSMP-23 module adds 1GB LPDDR4 RAM, 4GB eMMC and power management, integrated on a QFN-footprint PCB with excellent EMC, thermal and cost optimisations. The module is square, with a height of 2.6mm, and requires a single 3.3v supply. A full industrial operating temperature range of -40C to +85C is supported.
A wide range of interfaces is supported including dual USB 2.0 (with on-module PHYs), and dual Gb Ethernet. Other connectivity includes 3x UART, 3x I2C, 2x SPI, PWM, SAI and 2x CAN.
Advanced security features support security functions for IoT and industrial applications, ready for a CRA-compliant system implementation.
The QSMP-23 comes with a dedicated Yocto Scarthgap build, providing mainline Linux kernel, with full sources and toolchain supplied as well as extensive documentation.

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.
The standard QS module is 27mm square. The footprint-compatible 29mm QSX modules have 8 additional pins for high-speed interfaces such as USB-3 or PCIe
In addition they offer:
Guaranteed lifetime is a key reason to choose us – we have been shipping modules for over two decades, and have a track record of offering several products for well over 10 years. Each module that we sell is guaranteed to be available, in small or large quantities for at least 12 years from launch. This is a minimum, with expected lifetimes of 15 years where possible. Direct Insight has a unique track-record in maintaining partnership with our customers for the long-term, supporting you throughout the product life-cycle.
Because the TRITON-TX modules are manufactured in a high-quality small-batch production facility within the EU, 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, cheap modules are produced in large batches by volume-oriented contract manufacturers in the Far East, and once they are gone, they are gone.
Our BSPs whether for Linux, or other supported OS are 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 requires a reliable, production-ready BSP, and a ready-to-roll compatible tools setup. For Linux, we supply a pre-configured VM SDK so that the kit and tools are ready to use out of the box.
Further to our longevity guarantee, additional security is provided by the pin-compatible nature of theQS-Module ranges, which means that suitable baseboard designs can take all the modules from this family, from the low-end low-cost QSMP, to the i.MX8 based QS8M and allows older modules to be replaced by the latest designs, with new features, better price-performance, and renewed longevity.
Striving for the best technical support provision to our customers is what makes Direct Insight stand out. Using a system-on-module is all about achieving a quicker, smoother route to project completion. We have supported our customers in many hundreds of system-on-module projects over the last 20 years, and are uniquely placed to assist you.
The STM32MP157C processor features secure boot capability which potentially allows the user to secure the device against code modification, while preserving the ability to update. This is achieved by programming public keys into the device, against which the private-key signed image and data are validated. We offer secure boot programming during manufacture to enable customers to easily secure their device.
