What customers say
Customers highly value the Pimoroni Automation HAT Mini for compact Raspberry Pi projects, especially with the Pi Zero. The core appeal centers on its exceptional build quality and thoughtful integration of industrial I/O, featuring reliable screw terminals, a relay, and analog inputs. Users confirm that Pimoroni successfully miniaturized the functionality without compromising reliability, making it perfect for discreet monitoring installations. A significant strength is the accompanying Python library, which greatly simplifies setup and integration for many users. While the size necessitates fewer I/O options than the full HAT, reviewers agree the superior quality and dependable performance justify the investment. This positions the Mini as a professional, stable solution for serious IoT development.
Know before you buy
No, the board comes fully assembled. You can simply plug it onto your Raspberry Pi's 40-pin header and start using it immediately.
No, this board is designed for low-voltage systems up to 24V. It is not suitable for switching mains voltage (110V/240V) and attempting to do so is dangerous.
The Automation HAT Mini is compatible with all Raspberry Pi models that feature the standard 40-pin GPIO header, including the Pi 4, 3, 2, B+, and Zero series.
The board features 3.5mm screw terminals, which allow you to securely attach wires for your inputs, outputs, and analog sensors without needing specialized connectors.
The full-color IPS LCD provides a convenient way to monitor system status, sensor readings, or relay activity directly on the board without needing to check your terminal or a remote dashboard.
The three 12-bit analog-to-digital converters offer a 0-24V range with ±2% accuracy. This is ideal for general-purpose automation tasks like monitoring battery levels or environmental sensors, though it may not be suitable for high-precision laboratory measurements.
