Story
This is spi oled 3.3v-5.0v. Note: The Github link of this project is: https://github.com/mike-rankin/spi_oled_3.3v-5.0v. This project is reposted with the approval of this project creator. He is a good DIY maker who designs custom ESP32 IoT projects using Altium Designer, Arduino IDE and Fusion360!!!! Welcome everyone to follow him. This is his GitHub account, Mike Rankin, where you will explore more excellent projects.
/*********************************************************************
This is an example for our Monochrome OLEDs based on SSD1306 drivers
Pick one up today in the adafruit shop!
------> http://www.adafruit.com/category/63_98
This example is for a 128x64 size display using SPI to communicate
4 or 5 pins are required to interface
