The Pimoroni Automation HAT is a versatile home automation and industrial control board for the Raspberry Pi. With relays, analogue channels, powered outputs, and buffered inputs — all 24V tolerant — it provides a comprehensive I/O platform for monitoring and controlling real-world devices.
Each channel has an indicator LED for at-a-glance status monitoring, and the analogue channels feature dimming LEDs that reflect the current sensing value. Comes fully assembled with 3.5mm screw terminals for easy wiring.
Key Features
- 3 Relays – 24V @ 2A with NC and NO terminals
- 3 Analogue Inputs – 12-bit ADC, 0–24V range
- 1 Analogue Input – 12-bit ADC, 0–3.3V range
- 3 Buffered Inputs – 24V tolerant
- 3 Sinking Outputs – 24V tolerant
- 15 Channel LEDs – Visual status for every channel
- SPI Interface – With HAT EEPROM
- Extra GPIO – TX (#14), RX (#15), #25
- Screw Terminals – 3.5mm for secure, solderless connections
Ideal For
- Home automation systems
- Hydroponics and environmental monitoring
- Light industrial control

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.
- EEPROM
- A type of non-volatile memory that keeps stored data even when power is turned off. In a sensor module, it can be used to store settings or calibration data so they do not need to be re-entered every time.
- 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.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- 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.
