Communication Miracle with NXP i.MX91 Computing Power +++ GLYN in Hungary +++ Voted Distributor of the Year 2025

Direct-to-Board Soldering - Communication Brilliance meets NXP i.MX91 Processing Power

In our increasingly networked world, every millisecond and every milliwatt counts when it comes to computing power. The computer platform should also provide a large memory and as many interfaces as possible.

The ideal solution for this is a 27 x 27 x 2.7 mm System-on-Module (SoM for short).
And it comes with NXP i.MX91 computing power from the manufacturer Ka-Ro.

The solderable QS91 is produced on a QFN basis and can be directly machine-assembled.

1.4 GHz computing power - directly on your board
With a 1.4 GHz fast single-core ARM Cortex-A55 and 512 MB LPDDR4 RAM, the QS91 offers enough power to reliably calculate demanding algorithms and processes. Whether Industry 4.0 or Smart Home - your applications benefit from an optimized architecture with maximum efficiency and minimum energy consumption.

Versatile connectivity for maximum flexibility
Up to 60 GPIOs at 3.3V, 8 UARTs, 7 I²C, 8 SPI and Ethernet - the QS91 is a real communication miracle. This variety of interfaces makes it the ideal choice for integrators who need maximum connectivity in industrial control systems, sensor networks or home automation solutions - without compromising on space or integration.

Secure from the first line of code
With the integrated EdgeLock Secure Enclave from NXP, the module offers security features such as secure boot, tamper detection and eFuse key storage. This makes the QS91 not only powerful, but also a reliable partner in security-critical applications - from medical technology to critical infrastructure.

In summary
The QS91 from Ka-Ro is not just a SoM - it is a key component for your next embedded innovation. Solderable, machine mountable, powerful and safe. Download datasheet here.
