I measured the TI LaunchPad/Pacsat board combination and the weight was less than expected.
The combined weight was 2.9 ounces. The TI launch pad weighs 1.6 oz and the Pacsat board 1.2.
The extra combined ounce is attributed to the scales which measure only .1 degree.
This is a link to the TMS370 LaunchPad web site that includes documentation as well as schematic.
