Pimoroni – Automation pHAT

The most compact way to take control of and monitor your world!

A great set of features into this home monitoring and automation controller. With a relay, analog channels, powered outputs, and buffered inputs (all 24V tolerant) you can now hook up a plethora of goodies to your Raspberry Pi all at once.

Ideal for smart home and automation projects, giving your greenhouse intelligent sprinklers, or scheduling your fish feeding!

Features:

1 x 24V @ 2A relay (NC and NO terminals)
3 x 12-bit ADC @ 0-24V (ADS1015) (±2% accuracy)
3 x 24V tolerant buffered inputs
3 x 24V tolerant sinking outputs
3.5mm screw terminals
SPI pins broken out
Automation pHAT pinout
Compatible with all 40-pin header Raspberry Pi models
Python library
Female header and broken out pins require soldering

Software:

A super-simple to use Python library to take advantage of Automation pHAT’s multitudinous functions, with examples to get you started.

Notes:

• Loads for the outputs should be switched on the ground side, i.e. 12/24V (from supply) -> load -> output terminal -> ground (from supply)
• The relay can tolerate up to 2A each and should be switched on the high side
• The sinking outputs can sink a maximum 500mA total across the 3 outputs, so if you use a single channel you can sink the whole 500mA across it.
• The accuracy of the ADC is ±2%.
• Do not use to switch mains voltages!
