QSMP Solder-down module with STMicro STM32MP157C dual core ARM Cortex-A7
QSMP-15 tiny QFN-Style System-on-Module
QSMP-13 and QSMP-15 are 27mm x 27mm QFN Style solder-down system-on-modules with STMicro’s 
latest single and dual-core STM32MP1 ARM Cortex-A7 processors, plus RAM, Flash memory and power management. QSMP-15 and -25 modules sit within the Ka-Ro QS-Module family, which also includes SoMs based on STM32MP2, as well as NXP and Renesas processors. The QSMP-15 module is square, with a height of 2.3mm. Its QFN-type pinout style features a 1mm pitch with 100 edge-located pads providing unparalleled miniaturisation, thermal efficiency and EMI minimisation – the base functions as both a ground pad and a thermal conductor. The module requires a single 3.3v supply.
The QSMP-15 module’s STM32MP157C processor affords high performance via the dual 650MHz ARM Cortex-A7 processor cores and associated 3DGPU. There is 512MB of DDR3L RAM, up to 4GB eMMC Flash, and a wide range of interfaces (see table). Both modules offer an extended temperature spec of -25C to +85C. The QSMP-15 provides a wide range of connectivity including CANbus, UART (x3 – x5), SPI (x2), I2C (x2), Audio, Gb Ethernet, SD, USB Host and Client and a parallel or MIPI-DSI display.
QSMP comes with a dedicated development system, equipped with Linux BSP.

The QSMP module has its own development kit called QSBASE1 with parallel RGB display, and also works with the universal QSBASE4 kit which supports those QS modules with MIPI-DSI display interface. Both are supplied with Linux running out of the box.
QSBASE1
The QSBASE1 development kit is supplied with a QSMP-15 OR QSMP-13 module. There is an RGB connector for a touch screen (which can be optionally purchased), and connectors for SD Card, Gb Ethernet, USB Host. USB Power supply, and debug UART. All 100 module pins are brought to 0.1″ solder pads.
QSBASE1 with QSMP-15W
A special version of QSBASE1 includes the QSMP-15W module with Wi-Fi and Bluetooth subsystem. This devkit includes Molex 2.4/5GHz Balanced PCB Antenna 1461870100
QSBASE4
Most QS and QSX modules, including QSMP-15 may use the QSBASE4 baseboard for development purposes.
QSBASE4 is designed to accept socketed versions of all QS and QSX modules, and features:
- Gb Ethernet
- 2-port USB hub
- 2-Lane MIPI display connector – Raspberry Pi compatible
- 2-Lane MIPI camera connector
- Micro USB to UART bridge for debug
- USB type-C connector for client/power
- Expansion connector – RasPi power/I2C/SPI/UART compatible + CAN, SDIO
- JTAG ICE header
Special socketed versions of QS/QSX modules are connected via two 80-pin push-down connectors.
The QSBASE4 works with a standard Raspberry Pi 7″ touch display which is readily obtainable (we may also have stock). It is supplied complete with a USB-C cable for power and flashing, and a micro USB-B cable for debugging. The socketed modules are preflashed with a Linux image (contact support for details, and possible customisation).
QSBASE4 with Raspberry Pi Display
The QSMP module is available in three configurations. See the comparison table below (also the feature table above), and the part descriptions below the table.

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 15 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.
