Automation HAT Mini

by Pimoroni

Automate your world with Automation HAT Mini! Monitor and control up to 24V systems and see their status on the gorgeous full-colour display.

Don't be fooled by its size... Automation HAT Mini packs a whole bunch of functionality in. It has a relay, three buffered inputs, three outputs, and three analog inputs, all 24V-tolerant. Last but not least, it has a beautiful 0.96" full-colour IPS LCD to display the status of your systems.

Automation HAT Mini is perfect for home automation projects, giving your greenhouse intelligent sprinklers, for scheduling your fish feeding, or for controlling low-voltage lighting systems.

Features

  • 0.96" colour LCD (160x80)
  • 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
  • Pimoroni breakout-compatible pin header
  • Mini HAT-format board
  • Fully-assembled (no soldering required)
  • Compatible with all 40-pin header Raspberry Pi models
  • Python library
  • Schematic


Automate your world!

All of the inputs and outputs, and the relay, on Automation HAT Mini are 24V-tolerant and many low-voltage systems in home devices (and also in cars) run on either 12V or 24V. Automation HAT Mini is a great way to monitor and control them.

Use the buffered inputs to sense the on/off state of your devices, or get more granularity with the analog inputs that measure the input voltage with 12-bit accuracy. The sinking outputs can sink a total of 500mA across the three channels. For higher-current loads, you can use the relay that can tolerate up to 2A at 24V, and take advantage of the normally-open or normally-closed sides to give the correct failover state.

We've added a female header on the underside of the board with the correct pinout for our Pimoroni breakout range. This opens up a whole host of nifty possibilities! Pop an I2C Breakout Extender into the header, and then you can easily pop in one of our breakouts. No soldering necessary! Use an LTR-559 Light and Proximity Sensor to turn a device on automatically when it gets light or dark, or a BME280 Temperature, Pressure, and Humidity Sensor to trigger at a specific temperature or humidity threshold.

Software

As usual, we've made a super-simple to use Python library to take advantage of all of Automation HAT Mini's functions, with examples to get you started.

We've added support for the 0.96" LCD to our Automation HAT library so, when you run the installer, everything you need will be set up and installed. Nifty!

Our examples show you how to use all of the different functions on Automation HAT Mini and how to display their status on the LCD. Check out our Getting Started tutorial for more details!

Notes

  • Dimensions: 65x30x16.8mm
  • 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!

This is my second one - and again it worked great. I'm using this with a Pi Zero W and a lock from cdvilocks to create my own fully secure door lock for less than £50. More capable than any off-the-shelf big business lock, at half the price, and completely private.

I've been using the Automation HAT Mini for the last few years, and it has been an essential component of our manufacturing production floor. We have 7 Raspberry Pi 3B+ units with Pimoroni Automation HAT Minis running 24/7 using Node-RED, and the experience has been flawless. From development to deployment, it was a smooth sailing process with no issues encountered. We're currently in the process of building an additional 5 units because this product has proven to be perfect for simple and cost-effective industrial automation. Highly recommended!

The HAT is well done. The display is too small. Unfortunately the examples and information of the display are not updated. Lot of time wasted trying to write text in the display.

Within minutes it was plugged up and ready to go. The built in screen is lovely and the device works great!

As usual from pimoroni, this HAT makes a good impression. Unfortunately, I haven't had enough time to implement my project so far, but this will follow soon
