The board has an 8-pin 1.25mm-pitch JTAG connector (JST-ish, probably compatible with Molex PicoBlade/Multicomp Pro 34443/34453) on the bottom side, under the USB connector. (Connection hasn't been tested with a JTAG probe yet, though. The pins have been checked with a continuity tester that it goes to the Spartan-3AN JTAG pins.) The pinout is as follows: ***NOTE: THIS CONNECTOR USES 2.1V LOGIC LEVELS***
