Product Overview

The Hailege 3-Pack RP2040-Zero RP2040 Microcontroller PICO Development Board is a set of three compact development boards featuring the RP2040 chip, the same microcontroller used in the Raspberry Pi Pico. Manufactured by Hailege and sold by Hailege JP on Amazon.co.jp (ASIN: B0DMDV8YVB, model H-A-1772), this pack offers excellent value for makers and educators.

Each board is built around a dual-core Cortex M0+ processor with 264KB of SRAM and 2MB of flash memory. The boards come with unsoldered pin headers, giving you the flexibility to solder them yourself or wire directly to the board.

Key Features

  • RP2040 Chip: Powered by the same RP2040 microcontroller as the Raspberry Pi Pico, featuring a dual-core Cortex M0+ processor running at up to 133MHz.
  • 3-Pack Value: Three boards in one package reduce per-unit cost, ideal for prototyping multiple projects simultaneously or for classroom use.
  • Compact Form Factor: Board dimensions of approximately 21mm x 51mm make it suitable for space-constrained embedded applications.
  • Rich I/O: 20 GPIO pins (4 ADC-capable), plus SPI, I2C, and UART interfaces for connecting sensors, displays, and other peripherals.
  • Unsoldered Pin Headers: Headers are included but not pre-soldered, allowing you to choose your preferred mounting method or solder directly to the board.

Compatibility Guide

  • Development Environments: Fully compatible with MicroPython and the official C/C++ SDK. Arduino IDE support is available via third-party board manager.
  • Power Supply: Powered via USB Micro B (5V) or through the VSYS pin (1.8V–5.5V).
  • Pin Layout: Largely compatible with Raspberry Pi Pico pinout, but some pin assignments differ. Double-check your wiring when reusing Pico-specific shields or breadboard layouts.
  • Platform Independent: As a microcontroller, it works with Windows, macOS, and Linux development environments.

Ideal Use Cases

  • IoT Prototyping: Connect sensors and actuators for temperature monitoring, motor control, or home automation experiments.
  • Education & Workshops: The 3-pack is perfect for soldering practice, introductory microcontroller courses, or group projects.
  • Compact Embedded Devices: Ideal for wearable tech, portable gadgets, or any project where board space is at a premium.
  • Multi-Project Development: Run several prototypes simultaneously without buying individual boards.

Upgrade Considerations

  • Performance Limits: The RP2040 is designed for low-power, cost-sensitive applications. It is not suitable for heavy image processing or complex computations. Consider upgrading to RP2350 or ESP32-S3 for higher performance needs.
  • Memory Constraints: 264KB SRAM and 2MB flash are adequate for small to medium programs but may be insufficient for large data logging or graphical displays.
  • Soldering Required: If you are new to electronics, practice soldering on scrap boards first. The unsoldered headers require basic soldering skills.
  • Compatibility Check: Not all Raspberry Pi Pico libraries and example code will work out of the box. Verify pin assignments and clock settings before deployment.
