Hi Gerard and Mike,
  I have modified the address connection (from V+ to GND) for temperature 
sensor chip on outer hybrid.
  The latest schematic, layout, gerber and design files are upload to the 
WIKI. (https://wiki.bnl.gov/star/index.php/Hybrid_and_T-board)
  Please double check if there are any mistakes.
  Please let me know if you need any other files or documents.
  Thanks!

Hi Gerard,
  The schematic for v3.0 T-board is also upload to the WIKI, on which one set 
of temperature sensor chip and reset circuit is kept.
  Please double check.
  Thanks!

Best,
Jianing
