Automation HAT

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
