This is designed to fit the pin headers of a Raspberry Pi Pico, and it does. It seems well-made and I haven't run into any problems with it. The product documentation on Waveshare's wiki is excellent.

Funktioniert einwandfrei.

This is a great option to add a simple, easy-to-read display to your project. Even though it's designed as a simple add-on hat for the Pi Pico, I was able to easily get it to work with my Arduinos and ESP-32 projects. The display is plenty bright, and being OLED it has fantastic contrast. I'm a big fan of having a small display to do some simple debugging during development, and this display is perfect for my use.I've been quite pleased with Waveshare recently, as they provide a lot of value for the money and provide great documentation and example code. If you're looking for a great small OLED, look no further!

This 1.3-inch OLED display module is a fantastic addition to any Raspberry Pi Pico project. The 64x128 resolution and crisp OLED display make graphics and text look great, and the SPI/I2C interface options provide flexibility for connecting to your Pico. The included demo code for C/C++ and MicroPython made it incredibly easy to get started. It's a compact and versatile display for a wide range of applications.

It goes without saying that the Pico is an embedded application hardware board from the Raspberry Pi foundation, and is designed for minimalist projects. This board is a companion product to provide a monochrome display to a project such as an environmental monitor (though many other uses would benefit).What comes in the box is a display module in an ESD shield bag and a packing foam pad. As long as you can access the Waveshare Wiki page (web search) and figure out the organization: this product is under Displays/OLED/PicoOLED-2.23, you can access all the support documentation and software. But, this is just the start, and employing this display is a project in and of itself. Even marrying the display to the Pico board requires soldering pin headers (not included with either). The point is: until you gain experience with the Pico and this sort of development process, integrating this display will likely be intimidating, if not daunting. Fortunately, there are resources and help online to get up-to-speed.(Since I ordered this to review it (first), my real experience with it is pending.)
