This is a compact 3-Digit 7-Segment LED Display board, which uses the 5631BH Common Anode LED Display with the Titan Micro TM1637 LED Driver Chip. It is very similar to the many off-the-shelf variations, but is slightly more compact in that it has 3-Digits instead of 4-Digits, as most of-the-shelf versions are, and is thus targeted for applications needing only 3-Digits.

If board overhang isn’t an issue with the mounting technique, the 5631BH can be swapped for a 5641BH 4-Digit Display, as the 4th common anode lead is wired to the TM1637 Driver.

Also, all traces were intentionally left out of the end-plates so that they could be trimmed, if desired, to fit in an even more compact area that doesn’t require the #2 sized mounting holes.

SMD passives are 0805 size.

Schematic, gerbers, and bill-of-materials for this board can be found on GitHub as a sub-part of the Altura-MIDI-Theremin Remix Project, as this board was originally built to use with that project.
