Product Overview
This ultra-compact 0.49-inch passive matrix OLED display module delivers crisp, high-contrast monochrome imagery in an extremely small form factor. Engineered with the reliable SSD1306BZ controller and I2C serial interface, this display solution offers excellent readability, wide viewing angles, and low power consumption for space-constrained applications.
The module features a 64 x 32 dot matrix resolution with individual pixel control, providing clear and sharp graphics for small-form-factor devices. The I2C interface requires only two signal lines (SCL and SDA) plus power and ground, simplifying integration into existing designs. With a simple 4-pin interface (GND, VCC, SCL, SDA) and compact footprint, this display is ideal for wearable technology, portable instruments, and miniature control panels.
