The remaining pins are the no connection pins in the driver. Some of them are for test and some are just dummy. They have no use in the OLED display. How to Interface OLED Display with Arduino Board? Any microcontroller or board is must require for using this OLED display, for display ...
The 1/64 duty drive ensures smooth and reliable performance, while the 4-pin interface with GND, VCC, SCL(SCK), and SDA pins simplifies the connection process. Whether you're building a seven segment display arduino project or looking for an arduino 12c lcd, this OLED module is a reliable...
