This week I worked on creating the components list for our PCB. This included researching all the relevant components, finding footprints, and all but ordering the parts. Components included the Arduino SPI interface with SD cards, SD Card readers, 7 Segment Displays, encoders and decoders (which we’ll be using shift registers for) and all required LEDs, resistors and buttons. We pivoted from using encoders to shift registers and single 7 Segment Displays to the Max7219 which took a bit of adjusting on our planned Arduino pin layout. I looked into lead times and shipping costs to decide where we would be ordering from for each of these, made sure it fit in with our planned schedule, and updated the BOM. I’ve also started a barebones schematic and reached out to a third party for peer reviews. This fits in with the scheduled plan as I should be on track to send out the schematic this weekend and get feedback and iterate by next weekend.
