This super cool little OLED screen, 128 x 32 is YELLOW! I haven’t come across the yellow ones before and I’m a big fan of the blue and the white ones. They are super versatile.
Also, very easy to program. I wanted to see how this little cutie looks so I grabbed an ESP32 and Breadboard and connected them.
For ESP32 users, here is a pin-out reminder… (not my image)
Pin outs For the ESP:
SDA > GPIO21
SCL (marked sck on the board) > GPIO22
GND > GND
PVCC > VCC
If you don’t already have it, grab the Adafruit SSD1306 Library <— if you’re unsure how to do this see an earlier tutorial.
Once the library is installed, choose the ssd1306_128x32_i2c file.
Upload the code to your board! Don’t forget to hold the BOOT button on your ESP32.
