Overview

Introduction

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.

Features

  • 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.

Note

  • 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.

  4. Note: You will be prompted to install the driver during the installation process, we can click Install.

Install Arduino-Pico Core on Arduino IDE

  1. Open Arduino IDE, click the File on the left corner and choose "Preferences".

    Note: If you already have the ESP8266 board URL, you can separate the URLs with commas like this:

    https://dl.espressif.com/dl/package_esp32_index.json,https://github.com/earlephilhower/arduino-pico/releases/download/global/package_rp2040_index.json
    
  3. 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

  1. 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).

  2. Download the demo, open arduino\PWM\D1-LED path under the D1-LED.ino.
  3. 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).
