01SSD1306 essentials
The common 0.96" module uses the SSD1306 controller over I²C at address 0x3C. True OLED pixels mean perfect blacks and tiny power draw.
02Library setup
- Install Adafruit_SSD1306 + Adafruit_GFX.
- Begin with display.begin(SSD1306_SWITCHCAPVCC, 0x3C).
- Use display.display() after every draw.
03Drawing tips
Use the built-in 6×8 font for body text and big 2×/3× scale for headlines. Bitmaps are 1-bit; convert images with image2cpp.
04Power & burn-in
OLEDs draw 5–25 mA depending on lit pixels. Animate or invert the screen periodically to avoid long-term burn-in on static UIs.
