October 16, 2013: In January of 2013, manufacturing of the 990 was converted from through-hole assembly to surface-mount assembly. Many improvements in components were made. The basic circuit and package dimensions remain the same, but the name has been modified to "990C+" to signify the changes. See the 990 data package for details.
