Voltmake - Electronics Engineering - PCB Design - Firmware - Software

From Idea to Mass Production, From Concept to Reality:

I am Tomislav Brlek, an electronics engineer. I have a Master’s degree in Electrical Engineering (specialty in Electronics) from the Faculty of Electrical Engineering and Computer Science at the University of Maribor. I have several years of experience developing electronics in various different fields like LoRa and LoRaWAN, 4G communications, agriculture monitoring, smart city management, low power IoT devices, etc.


Services that I offer:

  • Consultation - I work with you from the beginning where I help you with initial idea creation. I lead in the most cost-effective and mass-production friendly direction.
  • PCB Design - I develop your schematic and create the PCB layout with high speed, low power, low cost and ease of manufacturing in mind.
  • Prototyping - I prototype the devices for you and deliver few high quality professionally made prototypes to your doorstep.
  • Firmware - I develop effective and safe firmware written in C programming language for any microcontroller out there.
  • Testing - I develop testers (SW, FW and HW) for the PCBs to assure the quality of the PCBs assembled at your manufacturer.
  • Software - I develop software for the tester to assure the quality of the PCBs assembled at your manufacturer.
  • Production - I can oversee production and assure PCBs are being produced with the standards necessary to be eco friendly and safe
  • 3d Design - I design, prototype and manufacture enclosures and any other piece that is needed.
