Hardware Connnection
The Raspberry Pi can share and connect up to three LED dot matrix screen panels. If there is only one panel, just connect the pins corresponding to the 😄 mark in the table below. [2]💥 and [3]💧 need to share the connection of the second and third panels at the same time.
The following table adds some icons for better visual distinction: [1]=😄, [2]=💥 and [3]=💧.

Working With Raspberry Pi Pico
Hardware Connection
Prepare Materials
- RGB-Matrix-P2.5-64 x 64 (this product)
- Raspberry Pi Pico (need to be purchased separately, if not available, it is recommended to buy the version with soldered pin headers, which is convenient for wiring.)
Hardware Connection
Environment Setting
With Pico, we use CircuitPython as an example of RGB-Matrix. If you are not familiar with CircuitPython, you can first learn the official recommended guide "Raspberry Pi Pico CircuitPython Getting Started Tutorial (English Version)".
This guide covers the basics of getting started with CircuitPython and the use of the editor.
CircuitPython Development Environment Setting
In order to facilitate the programming, development and debugging of CircuitPython, it is recommended to use the "Mu Editor" development software. You can use Mu Editor for Pico's CircuitPython development on Windows.
The following describes the development and use of Mu Editor under Windows.
Build and Use Windows Development Environment (Mu Editor)
- Download Mu editor and install it by steps.
- After the installation is complete, configure the language and select the mode for the first time. Since we are using CircuitPython, pay attention to the mode and select the CircuitPython option.
- After the configuration is complete, it will display that the device cannot be found, because Pico has not downloaded the CircuitPython firmware library.
- Download the CircuitPython firmware library and program it into Pico.
- Download the CircuitPython UF2 file.
- Hold down the BOOTSEL button, then plug the Pico into a USB port on your Raspberry Pi or another computer.
- Release the BOOTSEL button after connecting the Pico.
- It will install as a mass storage device named "RPI-RP2".
- Drag and drop the CircuitPython UF2 file onto the "RPI-RP2" volume. Your Pico will reboot, a new disk drive will appear named CIRCUITPY, and you're done flashing.
- There will be a default code.py file in the new disk drive, you open it with Mu Editor, and the content in it is: "print("Hello World!")", the specific opening steps are shown in the last figure.
- Open the serial port, click the blank space and press Ctrl+C, then press Ctrl+D or click the blank space of the code interface and press Ctrl+S to run the demo, and you can observe the running effect in the CircuitPython REPL window.
Select Mode
Load
Select file
Open the serial port
Run the demo
Software Download
- Download the sample demo.
Example
- After setting up the CircuitPython environment, copy all the contents under the CircuitPython directory in the downloaded Pico example to the recognized USB flash drive, and then you can run the example (there are 16 demos in this code).
- The PSD folder is a file in .psd format, which can be used to modify the text and pictures that need to be moved. The modified pictures need to be saved as "excellent" and the format needs to be converted to BMP format.
【Function Description】
- Display text
- Set scrolling effect
