For future improvements
(Schematic) Do not reset annotations for components as previously annotated components might have already been associated with BOM
(Schematic) Do not copy and paste symbols for different parts of the schematic as they might copy over other field values
(Schematic) Refer to application circuit in datasheets to connect various passives
(Schematic) Consider pulling out some unused pins as pads if the board is to be used for future development and iteration E.g.
Teensy
(BOM) Consolidate shipping orders for parts and components so that fewer deliveries are made
(Schematic) Use a
p-channel MOSFET for reverse polarity circuit protection
(Layout) Use SMD components for IR receiver and emitter
(Layout) Use standard 9-pin JTAG/SWD connector for burning the bootloader
(Firmware) Use WiFi to control IR emission
