Introduction
1.OLED 30P Shield is a display expansion board (Shield) from OLIGHKER that complies with the Arduino interface standard. It carries an onboard FPC 30P connector for directly attaching OLED displays with an FPC 30P interface, and works with any main board that supports the standard Arduino interface.
2.The shield communicates over I2C and occupies only 4 main board pins (3V3, GND, SDA, SCL) to power the OLED display and transfer data, preserving the board's I/O
resources for other expansions.
Specifications
| Pin | Direction | Function |
|---|---|---|

|
| GND | Power | Common ground |
| SDA | I2C data | I2C data I2C data line, connected to the main board's SDA
|
| SCL | I2C clock | I2C clock line, connected to the main board's SCL

FAQ
- Why is the screen all white?
- Check reset, chip select, data/command pins, and initialization model.
- What if the image has noise?
- Lower the SPI clock and shorten the connection wires.
