Overview

RP2040-Zero is a tiny, low-cost Pico-compatible microcontroller module based on Raspberry Pi RP2040 dual-core chip. Its castellated edge pads allow direct SMD surface mounting for mass production integration.

Technical Specification

Main Controller	RP2040 dual-core Arm Cortex-M0+, max 133MHz clock
Memory	264KB SRAM, 2MB onboard NOR Flash (W25Q16JVUXIQ)
Power Supply	ME621 LDO regulator, max 800mA output; support 5V USB-C power input. Independent power pins are reserved on board: 5V power input, GND ground, 3.3V power output for external sensor power supply.
IO Resources	29 multi-function GPIO pins, integrated 3-channel ADC, hardware I2C/SPI/UART/PIO peripherals. All GPIO pads are gold-plated, compatible with both manual soldering and SMT mass production.
Onboard Peripherals	USB-C port, BOOT download button, RESET button, WS2812 programmable RGB LED
Dimension	18.00mm × 23.50mm

Supported Development Environment

Programming Language	C/C++ SDK, MicroPython
Compatible IDE	VS Code, Arduino IDE, Thonny Python Editor
Compatible IDE	VS Code, Arduino IDE, Thonny Python Editor

Pin Definition

Equipped with 29 independently configurable multiplexed GPIO pins. Each single pin can be assigned as digital GPIO, PWM output, ADC analog input, or hardware communication interface (SPI/I2C/UART). Complete pin function allocation details are available in the official pinout diagram.

Quick Start Guide

Download firmware via BOOT button operation: Hold down the BOOT button first, then plug in the USB-C cable to enter firmware download mode.

Develop via Thonny (MicroPython rapid development) or official Pico C SDK (C/C++ high-performance development).

Short press the RESET button to restart running programs.
