Notes on building the first article

The first version of the ECPE-5 PIC Project Board was assembled on Feb. 5th, 2003 using those parts we could find at UOP. We (Dr. Turpin, Dr. Dunmire, and I) did get a unit to function, but there were some problems. Pictures of the PCB, the assembled prototype, and MPEG clips of the the prototype in operation are shown below.

Problems found:

Other notes:


These pictures show the PCB before assembly. Two prototype PCBs were fabricated by

Component side. Actual size = 4.1 x 2.5 inches.

Assembled Prototype

The prototype was tested with the ECPE-5 +5v Linear Power Supply (the board on the left in each picture).

Assembled with two small 5x7 dot-matrix LED displays.
Assembled with one large 5x7 dot-matrix LED display.
