The RP2040 Metro Board: Powerful Development Platform, Arduino-Friendly Features
The RP2040 Metro Board packs a punch in a familiar form. Built around the Raspberry Pi RP2040 chip, it offers robust processing power, ample memory, and generous GPIO pins, making it ideal for a wide range of projects.
Familiar Footprint, Extra Muscle:
- Arduino-style layout keeps things comfortable for experienced users.
- Extra space and debugging ports provide flexibility for more ambitious projects.
Dual Cores, Ample Memory:
- Two Cortex M0+ cores deliver impressive performance for demanding tasks.
- 264KB of RAM ensures smooth operation for complex applications.
Packed with Connectivity:
- 24 GPIO pins with 4 supporting analog inputs give you plenty of ways to connect sensors, actuators, and more.
- Micro SD card slot expands storage for data logging and larger projects.
- Onboard LEDs and NeoPixel driver add visual flair to your creations.
Seamless Debugging:
- Dedicated SWD and Pico Probe ports simplify troubleshooting and programming.
Effortless Pin Control:
- Unique RX-TX switch lets you choose between traditional Arduino pin order or hardware UART configuration with a flick. No more cutting or soldering needed!
Whether you’re a seasoned hobbyist or a curious newcomer, the RP2040 Metro Board offers a versatile and powerful platform to bring your ideas to life.
Features
