Cleaned up Schematic + Fixes

  • I tidied up the schematic making it much easier to read and decipher and also found that the W25Q12BJVS was wired up wrong. I also figured out that pgnd is not supposed to just be gnd, and needs a “star grounding” which is basically where pgnd and gnd is separate except at one point where they connect so that the higher voltage from the motor drivers doesn’t interfere with the lower voltage grounds from logic chips. So I made the changes and added that too.
  • I then worked on getting all these changes over to the pcb which was really annoying because some of the pins weren’t in the correct order and some of the resistors/capacitators were flipped so I had to manually go through and correct all that so the schematic would work as intended. I also thickened the traces from the motor drivers to the motor terminals because they were only 0.2mm thick traces (and should’ve been bigger because they’ve got to carry voltage to the motors).
  • Next up I want to update the case that I CADed to be more of a full & cooler looking enclosure.
