Making a Time Circuit Display Schematic

I’ve chosen the LED displays, found a matrix driver, and determined the final positions for each LED display on the faceplate. The next step in the time circuits project is to build a dedicated circuit board for each display. This process starts with creating an electrical schematic.

Dimensioning the Time Circuit Display Faceplate

I’ve figured out what LED displays I’m going to use and I’ve found the case they’re going to fit in, but before I can design a custom circuit board I need to figure-out how they’re going to be spaced in the enclosure.

Specifications for the Time Circuit Display Enclosure

Before I can start designing the time circuit display circuit board, I need to figure-out its outer dimensions, mounting method, and the exact positions of the LED displays. This starts with the enclosure the circuit board is going in: an LMB Heeger Crown Royal series #852.
