0.96inch OLED Display Module, Embedded SSD1357 driver chip, SPI Communication 64x128 resolution OLED display, 65K colors, clear and colorful displaying effect SPI interface, minimizes required IO pins Comes with online development resources (examples for //STM32) Operating voltage: 3.3V/5V (Please that the power supply voltage and logic voltage are consistent, otherwise it not work properly) Support interface: 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: ablut 32.5 x 26.0mm Control Interface: VCC --Power (3.3V / 5V input) GND--Ground DIN --SPI data input CLK --SPI clock input --Chip selection, low active DC --Data/ selection (high for data, low for ) --Reset, low active OLED and its controller: The built-in driver used by this OLED is SSD1357, which is a 128RGB * 128 Dot Matrix OLED/PLED controller with a 128*128*18bit as a display buffer area, which supports two color depths of 262k and 65k. And supports 8bit 8080 parallel, 8bit 6800 parallel, 3wire-SPI and 4wire-SPI, and other communication methods This module selects 4wire-SPI and 3wire-SPI as the communication method, which reduces the area of the module and saves the IO resources of the controller Colour:blue Material:Metal Package Contents: 1x RGB OLED Module 1x 7Pin Cable Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
