This design controls various sizes of RGB Led Matrix displays using an ESP8266 and the Arduino IDE. A great tutorial for getting it up and running is at: http://www.instructables.com/id/RGB-LED-Matrix-With-an-ESP8266/ The Arduino library is at: https://github.com/2dom/PxMatrix

SAMD21G18A Sensor Board with Color Oled

This Sensor Board is yet another variation of the other one on my site. It is not for sale with no real purpose in mind. It 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. Credit also goes to Microwavemont on Tindie and the SSD1331 library that he has on his site compiles error free using the Arduino IDE.

Assembly instructions -order the components on the parts list, follow the parts placement map and use the test sketches located here: https://0miker0.wordpress.com/esp8266-color-oled/ hand stuff the components, solder on the oled display but do not tape it down yet.

-connect the board to the Arduino IDE, pick the Adafruit Hazzah as the board, choose the right com port and load in one of the example sketches that I’ve modified for this hardware.
