Pixter Expansion Slot
The Pixter expansion slot is a 60 pin double sided card edge connector. the pads are .035" wide, with a .015" gap between pads, and a total of .050" center-to-center of the pads. the pcb is .047" thick which is a somewhat non-standard thickness. most pcb board houses with manufactor either .031 or .062 for their express and reduced cost production. there are a few production houses that will do the .047 for no additional cost, but only do them on a specific day of the week. Pin 60 is tied to the control(on/off) line of the S-1131 ( Media:S1131.pdf ) voltage regulator which allows the external cart to power the unit on and off. By using a Pixter Dev Cart, all the following pins can be used to develop projects:
