v1.1 - Fab doesn't like my 1.0

v1.1, too many problems I have to fix

1.0

I think it has an 80% chance to be fully functional, 95% chance to be partially functional

• 3D modeling is done
• circuits should be all correct
• I'm certain it can be assembled in theory
  use the pcb.zip, fixed some issues

v0.8 going to make it (if i confirmed the testing work)

going to make it (prototype!)

V0.7

made a mistake

V0.6 See if I can make it

• Tooling hole for PCBA
• Adjust some part placement
• Drill holes for M3 are correct now
• many more I forgot

Fixed rev0.5.1

rev 0.5 fixed

Rev0.5 If everything works, this is going to be rev 1.0

1. Use a better 1205 LED (much cheaper LCSC)
2. Fix the crystal CL, Rext
3. did a better job on wiring (but might come with power issues?)
4. fix the key position (0.01mm shifted so its a big fix)
5. generate better BOM file
6. add in LCSC and part number so easier to source
   Rev 0.4 is gone, I don't know where it went....

I think it is much better

Changes

1. fixed the pull-up resistors on the I2C so it might work now
2. add in the amazing STDC14 connector that I think might work with these thin traces.

v0.2 Alpha release

This PCB looks nice, might work, but have not yet been tested.
output_gbr should be fine for most PCB manufacturers
jlc.zip contain CSV for pick and place, BOM, etc.

Soldering might be hard...... if anything is not working plz let me know
