Hello community!
I don’t have a specific question, but I wanted to follow up on my previous topic regarding the NUCLEO STM32H755ZI-Q - Configuration. I encountered maximum power issues with my SimpleFOC shield and all the other boards I had on hand.
This led me to design a new medium-power dual motor FOC driver built for a Nucleo STM32H755ZI-Q board, which includes integrated current sensing and pull-up resistors for the integrated hall sensors. It is largely inspired by the simplefoc/SimpleFOC-DriveShield: A powerful Arduino shield for running BLDC motors project! Huge thanks to @Antun_Skuric for all the information available in his Git repo. I am currently at the delivery stage of this board, so I welcome any comments on my design for future version 2. Hopefully, there aren’t too many obvious issues, but I will keep you posted on this topic when I am finally testing the board.
Before you mention it, the headers shall be on the bottom side, manufacturer is aware and correcting the issue before shipment !
As I didn’t find any other solution for dual motor setup, this might be of interest for others in this forum.
While we wait for more, here are some information about it:
