OLED & Controller The integrated built-in controller used by this OLED is SSD1309, which has 128 x 64 bits SRAM, supports up to 128 x 64 pixel screen, supports SPI/I2C/ 6800 parallel port/8080 parallel port, 256-level brightness settings, this screen is 128 × 64 pixels, so the internal SRAM is not fully used. This module adopts four-wire SPI and I2C interfaces, with good compatibility and high transmission speed. Online guide/document: n9.cl/zcqtf Specifications Working Voltage: 5V/3.3V.

Package Content 1.51inch Transparent OLED x1 PH2.0 7PIN cable x1 Screws pack FAQ 1.Question:How many volts can an OLED module be used in a system? Answer: The OLED module is used in a 3.3V system by default, but after more than 24 hours of the burn-in test, it is found that it can also work normally in a 5V system. 2.Question:How many hours is the service life of an OLED module? Answer:Generally it is 50,000 hours under normal working conditions. 3.Question:What should I pay attention to when using this OLED module? Answer: 1. Be careful not to connect the power supply in reverse. 2. The same picture cannot be displayed for a long time, or there will be afterimages and cause damage to the OLED. 4.Question:Why does the OLED module not turn on when it is connected to the power supply? Answer: OLED does not have a backlight, and the display is self-illuminating. Only connect VCC and GND, and the OLED will not light up. Program control is required to brighten the OLED.

There are two driver interfaces on the OLED module: 4-wire SPI and I2C interfaces respectively. Two resistors can be soldered on the back of the module. The corresponding communication mode can be selected through the selection of resistors. Working Voltage: 5V/3.3V. Communication Interface: SPI/I2C. Controller: SSD1309. Resolution: 128 x 64.
