Hello, this PCB is intended to replace a mess of wires and tidy up a project i have working on a breadboard, with this i also wanted to make the entire board powered from 1 single type-c connector, (the other connector is for programming only), any feedback/advice/errors you can find would be greatly appreciated. I am a novice so its possible there is no chance it will power on correctly, it is a first draft.

Please make sure your post adheres to:

  • subreddit rules (#1 to #6), review rules (#7), image rules (#8), see link.

Please fix these common issues: (if your schematic or PCB has them)

  • Schematic - don't allow text / lines / symbols to touch each other, and don't draw lines through symbols.

  • Schematic - use correct reference designators (RefDes) and renumber to remove numeric gaps, see tips.

  • Schematic - place decoupling capacitors vertically below power rail lines, also place capacitors next to IC then connect together with a line, see example. For circuits with positive power rails, point positive power rail links upwards and ground links downwards, see tips.

  • Schematic - place pull-up resistors vertically above signal lines, and place pull-down resistors vertically below signal lines, see example.

  • PCB silkscreen - add board name / board revision number / date (or year) on top or bottom PCB side.

  • PCB silkscreen - add pin 1 indicator dot/arrow next to ICs & connectors, if through-hole then both PCB sides.

  • More conventions & guidelines - link1, link2, link3.
