Driver IC: SSD1306, Font Color: white, Voltage: DC 3.3-5V, PIN Interface: IIC or SPI optional. IIC Pin definition:-- GND: Power Ground. VCC: Power + (DC 3.3 ~5v). SCL: Clock Line. SDA: Data Line. SPI Pin definition:--GND: Power ground. VCC: Power. CLK: Clock line. MOSI: Data cable. RES: Reset line. DC: Data/commands. CS: Chip select (when not use can be grounded directly).

The display can run on 3.3v. It is legible, even with 4 lines of text. Highly recommended for projects that require some form of user interface. Use with Arduino, ESP8266, ESP32, STM32, etc. This is a really good way to add a very compact LCD to your project. No need to add some big bulky backlit LCD. High resolution OLED for any of your micro controller projects, 128x32 pixels gives you a nice sharp, crisp text output. The display performance is better than the traditional LCD display, it uses the very common I2C bus, and runs on the SSD1306 display driver. OLED display, no need backlight, self-illumination, Display Color: White. Plz note: These I2C OLED Display Modules come without pin headers.
