Raspberry Pi Pico RP2040-Matrix User Guide

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.
