Hallo to all robotic friends!
In an attempt to make a logic board, I developed a controller board to accommodate DRV8825 drivers and added some capacitors to filter the encoder signal. I also mounted some relays closer to the board for the limit switches. Additionally, I designed a board without motor drivers, which only includes filters, relays, and connectors.
The board with motor drivers is somewhat functional, but the drivers are too small. Maybe in the future, I will upgrade to better drivers, but for now, it is perfect for a smaller project.
Connectors: AliExpress Link
Relays: Google Search - G5Q-1-EU (This is what I had available at home.)

update, the relays are also to be able to mount induction senzors at limits
