CheeseBox with added OLED

I thought it might be fun to add an OLED screen to the CheeseBox when we made the printed circuit board. I’ve just soldered one into place and written a little driver for it. I rather like the look. Now I have to design a box and some buttons.

The wire is there to bypass a component that it turns out we don’t need. I’d added a level converter to take the 3.3 volt led signal up to 5 volts, because sometimes the Neopixels that we are using prefer this level. However, they seem to work just fine without it.

If you’re wondering what the back of the board looks like, and just how badly it is possible to solder a PICO to some pads on a PCB, then you can see the answer above…..
