Find attached ''mb276b.pdf'' epb schematics. For ST90E158LV low voltage devices (3.3V) the power supply has been trimmed on EPB in August 1999. The modifications was:

1) change resistor R7 from 2.00K to 1.5K

2) change resistor R12 from 3.9K to 2.2K

Hello Jorge,

Regarding the ST90158-EPBJ board, I have recently acquire one which has a V2.00 tag on it. Based on tarayre's comment and since this board has been checked by ST in july 2002 (see product delivery form provided with the programmer), it must be the latest available revision.

It will be a big improvement if this web site could provide latest version number for each ST9 tools (programmer and emulator).
