We had the first small run of boards made from this revision.

Status: PROVEN

Changes from v0.0 include:

  • Better user documentation in the README
  • Added a pull-down resistor for VTGT LED MOSFET (#6)
  • Cleaned up all the VCC/VTGT/VREF/etc naming to use "VTGT" (#9)
  • Improved the mode switch labeling (#8)
  • Used a variety of colors for the LEDs (#7)
  • Changed header wiring to make more sense (#1, #2, #3)
  • Added a bitmagic logic analyzer port (#4)
  • Added a cheatsheet to the back of the board (#10)
  • Revised mode switch to support JTAG and SWD on the CORTEX header (#5)
  • Added a solder jumper that allows bypassing the 330-ohm SWD hack resistor for I2C
  • Switched to M3 mounting holes
  • Re-ordered some level shifter inputs/outputs for more convenient routing
  • Improved switch footprints (pin 1 was incorrect, and didn't have a square pad)
  • Fixed some metric/imperial grid issues
