Frequently asked questions
How is the OLED display connected?
Most 0.96-inch OLED boards use I2C with SDA and SCL pins. Check the silkscreen labels on your board to confirm the pins before wiring or changing the code.
Can I connect 5 V sensors directly to the NodeMCU pins?
No. The ESP8266 operates at 3.3 V logic. Use a level shifter or 3.3 V compatible sensors to avoid damaging the chip.
