0.96 inch OLED Display Module, Embedded SSD1357 driver chip, SPI Communication 64x128 resolution OLED display, 65K colors, clear and colorful display effect. SPI interface, minimizing the number of necessary IO pins. Comes with online development resources (examples for STM32). Operating Voltage: 3.3V/5V (Please note that the power supply voltage and logic voltage must be consistent, otherwise it will not work correctly). Supports Interfaces: 4-wire SPI, 3-wire SPI. Controller: SSD1357 Resolution: 64 (RGB) x 128 Display Color: 65K color Display Dimension: 10.8624 (W) x 21.736 (H)mm Pixel Size: 0.0327 (W) x 0.146 (H)mm Module Size: Approx. 32.5 x 26.0mm Control Interface: VCC -- Power (3.3V / 5V input) GND--Ground DIN -- SPI data input CLK -- SPI clock input -- Chip select, active low DC -- Data/Command (high for data, low for command) -- Reset, active low OLED and its controller: The embedded driver used by this OLED is the SSD1357, which is a 128RGB * 128 Dot OLED/PLED controller with a 128*128*18bit SRAM as a display buffer area, supporting two color depths of 262k and 65k. It also supports 8bit 8080 parallel, 8bit 6800 parallel, 3wire-SPI, and 4-wire-SPI, among other communication methods. This module selects 4-wire-SPI and 3-wire-SPI as communication methods, reducing the module's footprint and saving IO resources for the controller. Color: Blue Material: Metal Package Contents: 1x RGB OLED Module 1x 7Pin Cable Only the above package content, other products are not included. Note: Light reflections and different displays may cause the color of the item in the picture to be slightly different from the real one. The allowed measurement error is +/- 1-3cm.
