The previously installed 1x2 board had traces missing from the schematic and would not work so it was scrapped and notes were made about how to fix the board for the next revision. A wide protoboard was selected for this project since it was a tested board and two had already failed. Solder paste was applied to the IC socket and resistors were added with a soldering iron.

Populating a wide protoboard

The protoboard was wider than the two previous boards and the overhang meant that the data wire between boards would have to reach out to the end, which would require more wire, or the wires could be run to the middle of the board and the data wires could meet there, which seemed like the best choice.

Wiring data and power to the wide protoboard

Since this project involved a lot of investigating small solder joints on surface-mount components, it seemed logical and reasonable to use jewelers magnifiying glasses. Many of the close-up photos taken for this blog used a stamp loupe for magnifying and that was cumbersome and easy to misplace.

Me looking confused about specs

After the protoboard was installed, the I2C scanner was run and all eight chips were visible. This was pretty exciting and meant that the individual IO points could be investigated and then keyswitches could be installed.
