RP2040-Matrix is a Pico-like MCU board based on Raspberry Pi RP2040. This castellated module allows soldering directly to carrier boards, adapting 20 × multi-function GPIO pins in this mini board. Onboard 5*5 RGB LEDs are for colorful lighting displays or simple images.
- RP2040 microcontroller chip designed by Raspberry Pi in the United Kingdom.
- Dual-core Arm Cortex M0+ processor, flexible clock running up to 133 MHz.
- 264KB of SRAM, and 2MB of onboard Flash memory.
- Onboard 5 × 5 RGB LED matrix for colorful lighting display.
- The castellated module allows soldering directly to carrier boards.
- USB 1.1 with device and host support.
- Low-power sleep and dormant modes.
- Drag-and-drop programming using mass storage over USB.
- 20 × multi-function GPIO pins.
- 2 × SPI, 2 × I2C, 2 × UART, 4 × 12-bit ADC, 16 × controllable PWM channels.
- Accurate clock and timer on-chip.
- Temperature sensor.
- Accelerated floating-point libraries on-chip.
- 8 × Programmable I/O (PIO) state machines for custom peripheral support.
- When the RGB LED matrix is fully on and the current is about 350MA, it is recommended to use a power adapter of 500MA or more.
- Please do not touch the RGB LED beads when the RGB LED matrix is fully on.
- It is not recommended to fully illuminate the RGB LED matrix for a long period of time, as it will cause the LEDs to accumulate heat and lead to high temperature, which will lead to a decrease in the life of the lamp beads or burn them out.

Arduino IDE Series
Install Arduino IDE
Download the Arduino IDE installation package from Arduino website.
Just click on "JUST DOWNLOAD".
Click to install after downloading.
Note: You will be prompted to install the driver during the installation process, we can click Install.
Install Arduino-Pico Core on Arduino IDE
Open Arduino IDE, click the File on the left corner and choose "Preferences".
Add the following link in the additional development board manager URL, then click OK.
Click on Tools -> Dev Board -> Dev Board Manager -> Search for pico, it shows installed since my computer has already installed it.
Upload Demo At the First Time
Press and hold the BOOTSET button on the Pico board, connect the Pico to the USB port of the computer via the Micro USB cable, and release the button when the computer recognizes a removable hard drive (RPI-RP2).
- Download the demo, open arduino\PWM\D1-LED path under the D1-LED.ino.
Click Tools -> Port, remember the existing COM, do not need to click this COM (different computers show different COM, remember the existing COM on your computer).
Connect the driver board to the computer with a USB cable, then click Tools -> Ports, select uf2 Board for the first connection, and after the upload is complete, connecting again will result in an additional COM port.
Click Tool -> Dev Board -> Raspberry Pi Pico/RP2040 -> Raspberry Pi Pico.
After setting, click the right arrow to upload.
- If you encounter problems during the period, you need to reinstall or replace the Arduino IDE version, uninstall the Arduino IDE needs to be uninstalled cleanly, after uninstalling the software you need to manually delete all the contents of the folder C:\Users\[name]\AppData\Local\Arduino15 (you need to show the hidden files in order to see it) and then reinstall.
