About Contronix Engineering
Contronix Engineering GmbH, based in Dresden, develops the electronics of innovative products as an engineering service. The team of eight experts covers the entire development process: circuit development in the fields of RF technology, power electronics and analog circuits, simulation of critical components with SPICE, FDTD, FEM and CFD, three-dimensional PCB design with Altium Designer including complex flex-rigid circuit boards, as well as firmware development for ARM Cortex microcontrollers in object-oriented C++ and based on Yocto/Linux. Communication interfaces such as USB, CAN, LAN, WLAN, BLE and cellular belong to the portfolio just as much as CAD design of small housings and auxiliary parts for 3D printing. Prototype boards are assembled in-house; for series production, EMC measurement and mechanical manufacturing, Contronix relies on a partner network. Focus areas are medical technology and endoscopy as well as organic and printed electronic systems.
