The Pimoroni Automation HAT is a versatile home automation and monitoring controller for the Raspberry Pi. It provides relays, analogue inputs, buffered digital inputs, and powered outputs — all 24 V tolerant — with indicator LEDs on every channel for at-a-glance status monitoring.
Connects to the Raspberry Pi via the 40-pin GPIO header and is controlled through a Python library with ready-to-use examples.
Key Features
- 3× 24 V / 2 A Relays – NC and NO terminals for switching loads
- 3× 12-Bit ADC Channels – 0–24 V input range (±2% accuracy)
- 1× 12-Bit ADC Channel – 0–3.3 V input range
- 3× Buffered Inputs – 24 V tolerant digital inputs
- 3× Sinking Outputs – 24 V tolerant (500 mA total across all three)
- 15× Channel LEDs – Visual status indicators (analogue channels dim proportionally)
- 3.5 mm Screw Terminals – Secure, solderless connections
- Breakout Pins – SPI, TX (#14), RX (#15), #25

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.
- breakout
- A breakout is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine contacts.
- GPIO
- General-purpose input/output pins are microcontroller pins you can set in software to read signals, switch devices on and off, or connect to peripherals. The number of GPIO pins matters because it limits how many buttons, LEDs, sensors, and other parts you can wire directly to the board.
- 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.
- 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.
