Automation HAT

Take control of and monitor your world with our ultimate jack-of-all-trades Raspberry Pi HAT! We've pulled together a great set of features into this home monitoring and automation controller. With relays, 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.

Better still each channel has an indicator LEDs which means at a glance you can see what's happening with your setup. Even the analog channels have dimming LEDs that allow you to see the value they are currently sensing - swish!

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

• Comes fully assembled (broken out pins require soldering)

Notes

• We recommend you use a set of brass M2.5 standoffs with Automation HAT to avoid pins contacting the HDMI port if the HAT is pushed down
• Loads for the buffered outputs should be switched on the ground side, i.e. 12/24V (from supply) -> load -> output terminal -> ground (from supply)
• The relays 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!
