Custom component library for ExpressPCB. This is a group of custom components and symbols for ExpressSCH and ExpressPCB I've developed as projects demand. Includes schematic component and board component for the LME49810 IC. Updated 1/25/09.
ExpressPCB circuit board file for the self bias CCS. To use you need to install the latest version of ExpressPCB then open this file. Ordering 1 mini board set using this file gets you 12 self bias CCS boards for $59.00. You will need to use a large pair of shears to cut the boards apart. Cut on the fine traces that denote the dividing lines on the top side of the boards.
