DH electronics

DH electronics has specialized on individual embedded systems such as System on Modules (SOMs), Human Machine Interfaces (HMIs), and IoT Gateways engineered and made in Germany for 30 years. The standard and customized products can be used in a wide range of applications such as building automation, mobility and transportation, measurement and laboratory technology, mechanical and plant engineering, medical technology, and healthcare. Longterm availability of 10+ years is guaranteed for all products and Mainline Linux support is offered. The office is located in southern Germany with short distances to the production site in Bavaria and to surrounding customers in Germany, Austria and Switzerland. DH electronics supplies customers worldwide and works closely with distributors to ensure excellent customer service.

Customized embeded systems made easy

DH electronics implemented a modular system that enables the quick, easy, and cost-efficient development of customized embedded solutions based on its standard products. As a full-service provider, DH electronics not only takes care of software and hardware development, but also project management and the coordination of project partners. DH is a pioneer for solderable SOMs and has developed solderable embedded computer modules with pre-tinned LGA ball grids for STM32MP15x and STM32MP13x. DH electronics is not just a SOM maker but offers excellent customer support in terms of standard, semi- and fully-customized devices where customers are guided from the first idea to the finished product and beyond.

Software support

DH electronics contributes to the Open Source community by upstreaming new projects to the Mainline Linux kernel and offers Mainline Linux support for products such as DHCOR STM32MP13, DHSBC STM32MP13, DHCOR STM32MP15 and DHCOM STM32MP15 from the very beginning on. A SOM design with STM32MP2 is already planned. Therefore optimizations, improvements and bug fixes are available to anyone. You will find the sources for our System on Modules and development boards or reference designs in the Mainline Kernel and can directly use Linux-Next on this device. Currently we use LTS Linux kernel 6.6.y. Apart from our own embedded devices we can also bring customer-specific devices Mainline. Due to the Mainline support updates can be also done easily and fast and will be supported by DH on a regular basis. We use a GitLab based CI/CD pipeline and can also carry out tests on real costumer hardware in our DH test rack.

Low-power solutions

DH electronics has more than 30 years of experience in the development of standard and customized embedded systems based on energy-saving Arm microprocessors. With the low-power strategy for our DHCOM STM32MP15, the power consumption of the SOM can be reduced to 10% compared to operation and the power consumption in run mode from typ. 1.4 -2 W to a few milliwatts. Detailed information can be found here.

Cooling without heat sink

We developed the 5-Cent Cooling Solution which makes expensive heat sinks obsolete and offers an space- and cost-efficient, robust alternative. With our cooling system, heat is dissipated from the processor through thermal vias into the inner copper layers of the PCB via a 5-Cent copper surface with the aid of a gap pad. Detailed information can be found here.

DH electronics in STMicroelectronics ecosystem

DH electronics relies on ST, an established manufacturer of microprocessors and microcontrollers, which promises long-term availability and highest quality. As ST Authorized Partner, we can therefore guarantee customers a long-term availability of their embedded systems of 10+ years. At the same time, customers benefit from the close cooperation with ST, as they can expect excellent support in terms of software and hardware, trainings and workshops regarding the use of ST products within DH electronics’ product families.
