Converter Prototype KiCAD Build Files.zipThese are the build files for the exact board seen in video. The schematic below is updated to include rework I had to do. MC33996 reset pin needs to be connected to reset of the ESP32 or 3.3V. I added shottky diodes to the relays and TVS diodes to the individual segment coils. Also changed the SOPWR pin on the MC33996 from 12V to 3.3V. So keep in mind if you want to use these gerbers as is, you will need to rework the board. The footprint on my ESP32 board was mirrors so I had to add the protoboard with the pins swapped.Zip Archive - 330.91 kB - 01/29/2018 at 18:20 |
