In Download > Projects > JTAG-lock-pick final schematic for new ARM JTAG was posted - the project will be named JTAG-lock-pick. You can find more info on elektroda's board (Polish only). People interested in this project are encouraged to download the file. The PCB presented below is based on that schematic.

Changes introduced to previous version (0.0.3):

  • 74LVC2G125 double buffers in place of single ones (...1G125) to make things smaller - the most important gain is decrease in the filtering capacitors count,
  • one of 74LVC1G14 inverters removed - 3.3V voltage is always active and D_USB LED is driven directly by PWREN pin,
  • many minor changes like order of signals in resistor packs or dual buffers.

I'm ordering the PCBs tomorrow (; They will be scheduled for second week of March. Stay tuned!
