OLEDs / NHD-0420CW-A*3 VDD Voltage level
« on: February 13, 2018, 10:23:28 AM »
I am integrating this character OLED into a custom automotive gauge board. I need to know if VDD has to be exactly 2.8V or if the 3.3V I/O and power supply from an MCU/MPU like a Teensy 3.5 will work as well? If not would it be better to translate to 5V? I already have 3.3V->5V translation in the schematic to begin with so that would be easiest to implement. If it makes a difference, I am using the SPI interface.
