Question about OLED, not an issue.

Hi! Thanks for useful project. One question: how about OLED you're using and 5v on SDA/SCL? Is it SSD1306 based? If so, I was unable to find information about 5v tolerance on input pins in the datasheet. Ali ones has only 3.3v LDO and nothing else, Adafruit ones has either buffer, or MOSFET based level shifter on board. Thank you in advance.

Hi, these OLEDs work smoothly with 5V. I suspect there are simply resistors in the lines to limit the current, and the internal clamping diodes do the rest.
