Pimoroni HAT Hacker HAT | Dual 40-Pin GPIO Prototyping & Expansion Board
Description
The Pimoroni HAT Hacker HAT is an essential expansion tool designed for developers and makers who need to connect multiple boards to a single Raspberry Pi. By expanding the single 40-pin GPIO header into two separate landing zones, this board lets you run two mini HATs or combine a main HAT with an auxiliary sensor or display module at the same time.
Engineered for clean and easy prototyping, the board comes with clear silkscreen labels showing pin functions and BCM numbers, completely removing the guesswork from wiring. Because the connectors come pre-installed, no soldering is required. Backed by durable metal standoffs and multiple mounting holes, it ensures a solid, professional, and reliable multi-board stack for your projects.
Key Features
- Dual GPIO Landing Zones: Expands one host port into two male headers for simultaneous multi-board attachment.
- Silkscreen Pin Labels: Every pin function and BCM number is clearly printed on the PCB for quick reference.
- Pre-Installed Connectors: Factory-fitted male and female headers allow instant connection without manual work.
- Solder-Free Plug-and-Play: Ready to use right out of the box with zero permanent modifications required.
- Metal Standoff Hardware: Includes durable black metal standoffs to maintain proper vertical space between stacked boards.
- Multiple Mounting Holes: Eight anchor holes provide secure mechanical fixing inside custom enclosures.
- Compact Slim Profile: Low 5mm height design fits easily inside standard protective project cases.
- Reliable Signal Flow: High-quality traces ensure stable communication across SPI, I2C, and UART lines.
- Wide Pi Compatibility: Works seamlessly with all 40-pin Raspberry Pi models and compatible single-board computers.
Benefits
- Runs Multiple Modules: Lets you use two expansion boards simultaneously on a single Raspberry Pi.
- Simplifies Testing & Debugging: Clear pin markings make multimeter checks and wire tracing fast and straightforward.
- Provides Mechanical Stability: Included metal standoffs lock stacked boards firmly in place to prevent loose connections.
- Saves Assembly Time: Pre-installed headers eliminate tedious soldering and setup delays.
- Keeps Builds Neat: Delivers a clean, professional layout for permanent embedded systems and enclosures.
Applications
- Multi-Sensor Prototyping: Connecting environmental sensors and display modules to a single Pi simultaneously.
- IoT & Communication Stacks: Pairing a wireless communication HAT with a local relay or control board.
- Embedded Development Labs: Testing custom circuits alongside standard commercial interface cards.
- Robotics & Automation Rigs: Integrating motor driver breakout boards with sensor fusion units.
- Hardware Testing Benches: Providing accessible breakout points for signal monitoring and diagnostics.
