What is the Breakout Garden to Raspberry Pi Pico Interconnect Adapter?
The Breakout Garden to Raspberry Pi Pico Interconnect Adapter is a small yet robust interface board designed to link Pimoroni’s Breakout Garden modules with the Raspberry Pi Pico using a standardized connector layout. It provides a plug-and-play experience that eliminates the hassle of soldering and wiring, allowing developers to prototype faster and cleaner.
Key benefits include:
-
Tool-less integration with Breakout Garden modules.
-
Perfect pin alignment with the Raspberry Pi Pico’s GPIOs.
-
Support for I2C, SPI, and analog sensors.
-
Compatibility with Pimoroni’s Python libraries.
Understanding the Raspberry Pi Pico’s GPIO Layout
The Raspberry Pi Pico features a dual-core ARM Cortex M0+ processor, 26 multifunction GPIO pins, and support for I2C, SPI, UART, PWM, and ADC. For developers looking to connect various sensors and displays, this makes it incredibly versatile.
The Breakout Garden adapter maps these GPIOs to standard Breakout Garden sockets, ensuring your breakout boards get the correct power (3V3), ground, and communication lines.
Breakout Garden Interface: A Modular Expansion Ecosystem
Pimoroni’s Breakout Garden is a modular plug-in system that simplifies electronics prototyping. It offers:
-
I2C and SPI breakout boards for sensors, displays, and inputs.
-
Auto-addressing on I2C devices, minimizing software conflicts.
-
Color-coded slots to distinguish communication protocols.
When using the interconnect adapter, you gain access to these breakouts directly from the Raspberry Pi Pico, leveraging the Garden’s modularity without sacrificing speed or flexibility.
Pin Mapping and Connectivity Explained
The adapter ensures proper GPIO alignment through its engineered PCB traces. Below is a sample mapping layout:
| Pico Pin | Function | Breakout Garden Pin |
|---|---|---|
| GP0/GP1 | I2C0 SDA/SCL | I2C Bus |
| GP2-GP5 | SPI0 | SPI Bus |
| 3V3 | Power | VCC |
| GND | Ground | GND |
All sockets on the adapter are pre-configured for correct wiring, eliminating guesswork and potential damage.
