① flash micropython firmware to your esp32
[↓ download micropython]
// one-time setup · takes ~2 min
② upload ssd1306.py to your board
// place in /lib folder on your esp32
③ wire your oled display
SDA → GPIO21 · SCL → GPIO22
VCC → 3.3V · GND → GND
// arduino_c++ tab works without any of this
// copy code → arduino ide → upload directly
