Automate your world with Automation HAT Mini! Monitor and control up to 24V systems and see their status on the gorgeous full-colour display.
It looks small but this Automation HAT Mini brings so many functionalities. It has one relay, 3x buffered inputs, 3x outputs, 3x analog inputs. All are 24V-toleran!
Aside that is also fits a 0.96" full-colour IPS LCD, quite useful to display your project status.
The Automation HAT Mini will be perfect for home automation projects: smart greenhouse, fish feeding on schedule, low-voltage lighting systems control, wake up morning device, pet feeding, etc.
Automate your world!
All of the inputs, outputs, the relay are 24V-tolerant which allow the Automation HAT Mini to control many home or car devices running under 24V, 12V or less. This hat will be a perfect companion to control and monitor the world around you.
The on/off state of a 12/24V device can be read thanks to the buffered inputs. When finer reading is required, the analog inputs can be used to read analog voltage (12-bit accuracy, value from 0 to 1023). The output can be used to control device by allowing the current to shink into the output terminal (total of 500mA across the three channels). If you need to control an higher current then the relay would be a great choice (max 2A at 24V). The relay features both type of contact: normally-open or normally-closed so you can use the one suited to your project need.
The female header underside of the board has the correct pinout for plug and play Pimoroni breakouts. As this connector brings an I2C bus, just plug ans I2C Breakout Extender into the header then you can easily pop in one of Pimoroni breakouts. No soldering required! Using a LTR-559 Light and Proximity Sensor with allow the Hat to detect if light or dark environment. Using a BME280 sensor (Temperature, Pressure, Humidity) allows to trigger an alert or a device when specific temperature or humidity threshold is reached.
Software
Pimoroni made is product super simple to use thanks to the Python library. The library pf Automation HAT Mini brings functions to develop your own code. It also includes examples to get you started.
The support for the 0.96" LCD is also included into the Automation HAT library So, when you run the installer, everything you need will be set up and installed.

Important 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!
