Use when wiring or coding an SSD1306 128x64/128x32 OLED over I2C (or SPI) on ESP32, Pico, or Arduino. Covers the 0x3C address trap, the 1KB framebuffer RAM cost, MicroPython ssd1306 lib quirks, Adafruit GFX/SSD1306 on Arduino, drawing robot faces with primitives, real refresh-rate limits, burn-in avoidance, and the I2C debugging checklist.
