I had decided to use the MCP port expander in order to control several of these over I2C when I stumbled upon May Fourth's Sig7Seg design on Tindie. I noticed that she was using the TBD62083 in order to drive the digits, but I wanted a better footprint for mine. I wanted to be able to hot-swap and test the units without soldering the wires right to the board and I wanted to make it compatible with the QWIIC ecosystem. So I designed the board, ordered the parts, and got to work cooking them over a hotplate in the backyard.

I noticed there was one wiring error in the board, which I have since updated in the design files. It was trivial to fix, however, so I just soldered small wires onto mine instead of reordering the boards.
