With my extensive experience in developing and testing firmware for a wide range of microcontrollers, I am confident that I can deliver the results you are seeking for this project. I understand the frustration that comes with a failed circuit design, which is why my approach revolves around meticulous planning, thorough testing, and swift troubleshooting.
In terms of my skills, I have a strong grip on Circuit Design, Electrical Engineering, Electronics, and Microcontroller programming -- all of which are imperative for successfully creating a solid BLDC controller. Additionally, my familiarity with the LM2596HVS for voltage conversion would prove beneficial in integrating it into the circuit design.
By resolving your issue with the burnt PCB effectively and getting your controller up and running smoothly, I aim to make up for the two months lost in your previous efforts. Let's team up on this project - together we'll create a PCB that not only functions impeccably but also meets your specific requirements.
