Revision History

Revision 3.3

  • Add a protection diode to Vdd of the regulator.
  • Move the switch solder points out slightly to make them easier to reach.

Revision 3.2

  • License the project with the CERN OHL.
  • Include the CERN OHL notice in the silk screen of the boards.
  • Include build documentation.

Revision 3.1

  • Make the button fingers slightly longer; annotate them in the silk screen.
  • Extend the thermal pad under the LED past the body of the LED to make it a little easier to hand solder.
  • Connect the 3rd button solder pad to the middle for greater switch options.
  • Stockton logo in the solder mask.
  • Curve the right-hand end of the LED thermal trace; expose some of the trace for better dissipation.

Revision 3.0

  • Change current limiter to a 350ma current regulator.
  • Move current regulator close the edge of the board.
  • Change primary labelling from silk screen to solder mask.

Revision 2.0

  • Change shape of boards from a complete circle to a circle with the top and bottom truncated. This improves contact between boards and the copper tape at the edges and also makes the board cheaper to produce.

Revision 1.0

  • Initial release
