Description:
This compact OLED display module offers a high-performance visual solution based on the widely adopted SSD1306 driver IC. It features a 128×32 array of self-illuminating white organic light-emitting diodes, providing excellent contrast and wide viewing angles. The module's physical dimensions are minimized thanks to a back chip-mounting pad, resulting in a length of 33mm and a width of 20mm. This small form factor, coupled with its low power requirements (approximately 25mA at 3.3V/5V for full illumination and 2mA at 3.3V/5V when off), makes it suitable for battery-powered and space-constrained applications such as wearable technology, miniature gaming devices, and custom desktop interfaces.
Interfacing with this display is simplified through the I2C communication protocol, and an internal power-on reset circuit ensures reliable operation. It offers broad compatibility with a variety of microcontroller platforms, including the Arduino UNO and Leonardo, the ESP32 and ESP8266 SoCs, and the FireBettle-M0 development board, facilitating seamless integration into diverse embedded systems.
Note: Turn the pixels off when you are not using the display to prevent using some pixels for too long to darken them, which will cause the brightness uniformity problem.
