Lessons learnt

Good practices to continue for future projects

  • Do not reset annotations for components as previously annotated components might have already been associated with BOM
  • Do not copy and paste symbols for different parts of the schematic as they might copy over other field values
  • Refer to application circuit in datasheets to connect various passives
  • Consider pulling out some unused pins as pads if the board is to be used for future development and iteration E.g. Teensy
  • Consolidate shipping orders for parts and components so that fewer deliveries are made
  • Use a p-channel MOSFET for reverse polarity circuit protection

V2.0

For next iteration

  • Use SMD components for IR receiver and emitter
  • Use standard 9-pin JTAG/SWD connector for burning the bootloader Use standard 9-pin JTAG/SWD connector for burning the bootloader
  • Use WiFi to control IR emission
