I’ve been keeping an eye on the SSD1331 library to see if it would eventually work with the ESP8266 wifi modules. I noticed the support for it appeared one day with the Adafruit library so I tried it out on my Adafruit Hazzah and success!
I wanted a clean design without jumper wires so I created revision 1 of this design below. All hardware appears to work fine so far. It’s a pretty simple design. No buttons, switches or sensors of any kind. Just a microUSB connector for power and uploading new sketches, an LDO, FTDI usb interface, ESP and a 0.95″ color oled display.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
