Below, you see the layout for the test version, ordered from JLCPCB:

TODO

Lessons learned after the test version

• Remove Silkscreen text from top side. Either delete or move to bottom side.
• Add useful information to bottom side. Such as link. Or maybe also fun stuff, its free (silkscreen) real estate after all.
• Add pin 1 indicator to Shitty Add-on header.
• Add 2 step toggle switch to switch between external battery and USB C.
• Consider adding button(s). And/or encoder.
  • Added two buttons.
• Add numbering to UPDI programming header.
• Add github link.
• Add LED for SoC, so we can run blinky.
  • Wont do, no pin real estate.
• If keeping USB LED, add footprint for resistor in series. Also make it so that the USB LED is off by default and only blinks during transfer.
  • Removed USB LED.
• Fix MINUS LEDs.
  • Split LEDs to two different pins, so brightness can be controlled individually.
    • Will not do, cause we now use acryllic instead, so brightness should be the same.
  • Minus LEDs should use diffused LEDs,
    • Did not choose this method
  • or add a Diffuser acryllic as minus with sideways LED. Press-fitted in hole in the PCB.
• Add accelerometer or similar
• Swap ring out for sideways LEDS. WS2812B-4020.
  • Added more LEDs also.
• Double check all components to see if we need an LDO.
• Remove backplate for batteries. Instead use battery box with possible 3d printed holder.
  • Will make 3d printed holder when needed later.
• Add LDO.
  • Hopefully not needed for full device, as 3xAAA goes down to ca 3.2, and LEDs probably just get a bit dimmer at that point.
  • Added LDO for accelerometer.
