This Sensor Board is yet another variation of another one on my site. It is not for sale with no real purpose in mind but the design files to make your own are here. The project was created as design challenge. My full time job is pcb design work and as a hobby I enjoy experimenting with new design ideas.
This was one of the more challenging designs I’ve worked on in a while. A few times I’d given up on routing it. Evan using four routing layers I found it tough. The idea was to hide the bezel of the display behind the board but have sensor components on that same board. It would look something like a little tiny television with all the components around the edges.
This latest revision has fixed a few issues I found on previous versions but the design idea can possibly help others in some way. Full credit goes to Adafruit for publishing the Feather M0 design files along with the bootloader. I used the Feather design to create the schematic for my board.
[dombeef] originally built pocketTETRIS as a Father’s Day gift for his Tetris-loving pops. However, having finished the project he’s decided to share it with the universe, and it’s looking rather sweet. He made the game the smallest he could make, with size limitations imposed by a 0.96” OLED display, the coin-cell battery pack, and his desire…

Rene van der Meer designed this breakout board for a bare OLED display:
I’ve been playing with cheap OLED display breakouts for years, incorporating complete boards into my projects – an easy, but bulky solution. Now that I’ve had some practice designing circuits and PCBs, it’s time for my next challenge: soldering the display FPCs directly to my own boards.
I designed this board to try out a minimal circuit before integrating it into any larger projects, and to figure out the best way to solder flexible circuits to my boards. Since all of my new microcontroller-powered board designs only require 3.3 V, I haven’t added any 5 V tolerant level shifting. What’s left is a bare minimum circuit to drive a Solomon Systech SSD1306 using SPI at 3.3 V.
