qdSOM STM32MP13x: an embedded system-on-module for industry and IoT

The qdSOM: a versatile embedded solution for demanding applications

System-on-module technology has become indispensable in modern embedded development. It is used wherever compact dimensions, modular architectures and high computing power are required, for example in industrial automation, medical technology, transport, communications, consumer electronics and connected IoT devices.

querdenker engineering developed the qdSOM STM32MP13x for these fields: an energy-efficient, industrial-grade system-on-module with a wide range of interfaces and a lifecycle concept.

Technical highlights of the qdSOM STM32MP13x

The qdSOM is built on the STM32MP13x processor from STMicroelectronics.

General characteristics:

• compact dimensions: 29 x 29 x 3 mm
