About the Engineering Office

Helmut Gundermann Mikroelektronik is an engineering office in St. Leon-Rot near Heidelberg, led by Helmut Gundermann, graduate engineer (FH) in telecommunications engineering. The office offers consulting and development of disruptive technologies, EMC design, on-site EMC measurements with interference suppression and training, as well as expert reports for LED and EMC. Further services include hardware and firmware development (PLC, DSP, FPGA in C, VHDL, Assembler), LED display development with LED boards and controllers, image processing, design of enclosures and frames, planning of LED video walls and PV consulting. Reference projects range from LED video walls for airports and trade fairs and RF control systems for the Max Planck Institute for Nuclear Physics to expert reports for Porsche and AT&T. The former Gundermann Mikroelektronik GmbH was deregistered as of 1.3.2024; since then, activity has been carried out as a freelance engineer, with LEDALL as a partner for manufacturing, distribution, installation and service of LED displays.
