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.

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.
