The Automation HAT is a versatile home monitoring and automation controller for Raspberry Pi. With relays, analog channels, powered outputs, and buffered inputs — all 24V tolerant — you can connect a wide range of sensors, motors, and actuators to a single board.
Each channel has indicator LEDs so you can see the state of your setup at a glance. The analog channels even have dimming LEDs that reflect the current sensor value. A Python library with examples makes it quick to get started.
Key Features
- 3× 24V @ 2A Relays – NC and NO terminals for switching high-side loads
- 3× 12-bit ADC (0–24V) – ±2% accuracy for analog sensor readings
- 1× 12-bit ADC (0–3.3V) – For lower-voltage analog inputs
- 3× Buffered Inputs – 24V tolerant digital inputs
- 3× Sinking Outputs – 24V tolerant, up to 500 mA total across all three
- 15× Channel Indicator LEDs – Plus power, comms, and warning LEDs
- 3.5 mm Screw Terminals – Secure, tool-friendly connections
- Breakout Pins – SPI, TX (#14), RX (#15), and #25 broken out
- Python Library – Simple API with input, output, and relay examples
- Fully Assembled – Broken-out pins require soldering
Compatibility
- Raspberry Pi 3B+, 3, 2, B+, A+, Zero, and Zero W
Warning: Do not use to switch mains voltages!
Important Notes
- Use brass M2.5 standoffs to prevent pins contacting the HDMI port if the HAT is pushed down
- Buffered outputs switch on the ground side: 12/24V (supply) → load → output terminal → ground (supply)
- Relays should be switched on the high side (up to 2A each)
- Sinking outputs share a 500 mA total budget — a single channel can use the full 500 mA
- Software does not support Raspbian Wheezy
Ideal For
- Smart home and building automation
- Greenhouse monitoring and automated irrigation
- Industrial sensor and relay control
- Aquarium and pet feeding automation
Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- ADC
- An analogue-to-digital converter reads a changing voltage and turns it into a number the microcontroller can use. It matters when connecting analogue sensors such as light, sound, or variable-resistor sensors.
- API
- An API (application programming interface) is a defined set of commands or functions that lets one piece of software interact with another, such as a library, operating system, hardware driver or online service. When something offers API support, it means you can control or query it from your own code rather than only through its built-in menus or buttons.
- breakout
- A breakout board carries a small or fine-pitched component and brings its connections out to standard, breadboard- and header-friendly pins. Describing a part as a breakout means it can be wired into a project without soldering directly to the component's tiny contacts.
- HDMI
- HDMI is a common digital video and audio connection used by computers, media players, and many displays. If a display kit has HDMI input, it is usually much easier to test with a single-board computer because it can act like a normal monitor.
- M2.5
- A metric screw thread size with a 2.5 mm nominal diameter. It matters for mounting because screws, standoffs, and holes must use the same size to fit securely without damaging the board.
- RX
- RX means receive, usually showing data being received by the board. An RX indicator LED can help with troubleshooting USB or serial communication.
- SPI
- A fast serial communication bus often used for displays, memory cards, and sensors. It matters because SPI devices need specific pins for clock and data, plus a separate chip-select line for each device.
- TX
- TX means transmit, usually showing data being sent from the board. A TX indicator LED can help you see when the board is communicating or uploading code.
