<p>Freigegebene technische Dokumentation veröffentlicht; Text-only und noindex</p> <p><b>Neue Seite</b></p><div>__NOINDEX__<br /> &#039;&#039;&#039;Documentation notice:&#039;&#039;&#039; This technical documentation was independently rewritten from an archived supplier source. Check technical details and commands against the product version and manufacturer documentation before use.<br /> <br /> == Summary ==<br /> This document describes the Waveshare 1.51-inch transparent OLED module with 128×64 resolution, an SSD1309 controller, and SPI/I2C interfaces. It includes wiring examples for Raspberry Pi, STM32, and Arduino, along with test commands.<br /> <br /> == Related products at JW Tech ==<br /> * [https://shop.jw-tech.eu/p/WSAL22545 WSAL22545 – 1.51inch Transparent OLED, 128×64 Resolution, SPI/I2C Interfaces, light blue color display]<br /> <br /> == Technical overview ==<br /> * Resolution: 128 × 64 pixels; display size 35.05 × 15.32 mm; pixel size 0.254 × 0.254 mm<br /> * Operating voltage: 5 V / 3.3 V; communication via 4-wire SPI or I2C<br /> * Integrated controller: SSD1309 with 128×64-bit SRAM; supports SPI, I2C, 6800 and 8080 parallel ports, and 256-level brightness settings<br /> * Pinout: VCC (5V/3.3V), GND, DIN, CLK, CS (active-low), DC (high = data, low = command), RST (active-low)<br /> * Hardware configuration: Two resistors on the back select the interface; factory default is 4-wire SPI; switching to I2C requires soldering the corresponding 0Ω resistors and adjusting DEV_Config.h<br /> * Raspberry Pi connection: VCC to 3.3 V, GND to ground, DIN to SPI MOSI or I2C SDA, CLK to SPI SCLK or I2C SCL, CS to CE0, D/C to GPIO6, RES to GPIO2<br /> * For Raspberry Pi, run `sudo raspi-config` in the terminal to enable SPI or I2C under Interfacing Options, then reboot<br /> * Libraries: BCM2835, WiringPi, and lgpio availability depends on the Debian release; on Bookworm only lgpio can be installed<br /> * Python environment: install python3-pip, python3-pil, python3-numpy, spidev, and python3-smbus<br /> * Test demo: download and extract the demo package, then run the C demo with `sudo ./main 1.51` or the matching Python script<br /> <br /> &#039;&#039;&#039;Commands and examples – verify before use:&#039;&#039;&#039; <br /> &lt;syntaxhighlight lang=&quot;text&quot;&gt;<br /> sudo raspi-config<br /> sudo reboot<br /> sudo make clean<br /> sudo make -j 8<br /> sudo ./main 1.51<br /> sudo python3 OLED_1in51_test.py<br /> &lt;/syntaxhighlight&gt;<br /> <br /> == Notes and version constraints ==<br /> * The exact name of the Python test script for the 1.51-inch module is not fully specified in the source; verify before running.<br /> * Switching from SPI to I2C requires soldering and editing DEV_Config.h; exact steps are version-sensitive.<br /> * Displaying the same image for extended periods may cause afterimages and damage the OLED.<br /> * Do not reverse-connect the power supply; connecting only VCC and GND without program control will leave the display dark.<br /> * Current-consumption figures in the FAQ refer to other OLED models; specific values for the 1.51-inch transparent OLED are not provided in the source.<br /> <br /> == Source and revision record ==<br /> * [https://www.waveshare.com/wiki/1.51inch_Transparent_OLED 1.51inch Transparent OLED - Waveshare Wiki]<br /> * Source revision: 70813<br /> * Captured: 2026-09-03T04:08:06+00:00<br /> * SHA-256: &lt;code&gt;66e79ed74128a2f80d604bd8a11d1410cdf59c3ec65e20ab0794cc86f4f83c7f&lt;/code&gt;</div>
