The Automation pHAT is a compact home monitoring and automation controller for Raspberry Pi. With a relay, analog channels, powered outputs, and buffered inputs — all 24V tolerant — you can connect a wide range of sensors and actuators to your Pi in one neat package.
It uses the same Python library as the larger Automation HAT, automatically detecting which board is connected. The library includes examples for reading analog and digital inputs, switching outputs, and controlling the relay.
Key Features
- 24V @ 2A Relay – NC and NO terminals for switching loads
- 3× 12-bit ADC Channels – 0–24V input range via ADS1015 (±2% accuracy)
- 3× Buffered Inputs – 24V tolerant digital inputs
- 3× Sinking Outputs – 24V tolerant, 500 mA total across all three
- 3.5mm Screw Terminals – Secure, tool-fastened connections
- SPI Pins Broken Out – For additional expansion
- pHAT Form Factor – Compact size for space-constrained builds
Specifications

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.
- Low-voltage DC
- Direct-current power at relatively low voltages, commonly used in battery, microcontroller, and small electronics projects. This matters because the connector is intended for DC wiring up to its rated voltage and current, not mains household wiring.
- pHAT
- A smaller add-on board format for Raspberry Pi, similar in idea to a HAT but usually not full-sized. It matters because pHAT compatibility can affect how neatly a board stacks or fits into a Raspberry Pi project.
- 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.
