Rene van der Meer designed this breakout board for a bare OLED display:

SSD1306 1.3″ OLED SPI breakout board

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.

Blecky’s latest project on Hackaday.io is an EEPROM/Flash emulator with a fun name:

EEEmu SPI

The EEEmu SPI emulates any Serial Peripheral Interface Bus EEPROM or Flash memory chipsets up to an interface speed of 25MHz. It also supports any supply and interface voltage between 1.8 to 5 Volts and can be configured to support even the largest of memory sizes.
