Monarco HAT
Industrial grade I/O board for the Raspberry Pi
Create a PLC from your Raspberry Pi, mount it on a DIN-rail and interface it with industrial sensors and devices directly. (I)IoT and Industry 4.0 ready, from prototyping to professional solutions.
Monitoring, archiving and control
The Monarco HAT is known to bring the best price to performance ratio in the following application areas:
- Data acquisition (DAQ), data logging
- Monitoring of machines and processes
- Collecting data from legacy PLCs
- (I)IoT gateway for legacy systems
- Communication gateway (Modbus RTU/TCP, OPC UA, MQTT, REST, SQL via ODBC etc.)
- Universal PLC for non-critical applications
The Monarco HAT has become an integral part of my toolbox for troubleshooting purposes in renewable energy and oil&gas automation. It gives me more freedom and possibilities than other way more expensive data loggers.Offshore services for oil&gas and renewable industries, Belgium
The product is well made and has been thought out well. The Monarco HAT is the best option to transform plain Raspberry Pi into a more industrial device.Omond-Tong Consultancy Ltd, United Kingdom
I am using Raspberry Pi 3 with the Monarco HAT to control a ground source heat pump with buffer combo which generates heat and hot water for our house. The Monarco HAT turns Raspberry Pi into a stable and reliable platform to implement long running control operations.

Developing solutions with the Monarco HAT
It's the software which brings any hardware device to life. Use the Monarco HAT with the software platform of your choice.
Professional software
Our first choice for programming is REXYGEN, a family of software products for projects in automation, robotics, data acquisition, process control and feedback control in general.
REXYGEN offers a graphical development environment for programming the algorithms. You can use standard desktop or laptop PC. You create the algorithms from the so-called function blocks. The library includes countless items (timers, comparators, filters, PID controllers and many more).
Open source
We understand the value of open source software and freedom of choice.
- Open source library for the C language
- Open source library for Node.js
- Open source library for Node-RED
- Complete documentation of the interface so that anyone can develop libraries for additional frameworks and languages (Python, C#, etc.)
GitHub repository
All the above mentioned Monarco HAT resources are available in public GitHub repository.
3rd party integrations
Programming with REXYGEN
- Graphical programming without hand-coding
- Industry-proven function blocks to use and re-use
- User interface (HMI) for desktop, tablet and smartphone
- Easy integration into business IT infrastructure (ERP/MES)
- REST API for integration with virtually any system, framework or programming language
- Up to 2 ms sampling rate with standard Raspbian distribution

Frequently asked questions (FAQ)
Additional information about the Monarco HAT
What Raspberry Pi models are supported?
The Monarco HAT board works well with Raspberry Pi models B+, 2, 3, 3B+ and 4. The metal enclosure is currently available only for models B+, 2, 3 and 3B+.
Can I use multiple HATs with a single Raspberry Pi?
No, HATs are not stackable by definition. A HAT has to have an EEPROM onboard that automatically configures it. This mechanism does not support stacking.
When will I receive my Monarco HAT?
We typically ship the Monarco HATs in 1-2 business days after your order is placed. Delivery time is about 3-5 business days within Europe and 10-12 days outside Europe.
What does 'HAT' mean?
A 'HAT' (Hardware Attached on Top) is an add-on board for Raspberry Pi that conforms to the HAT specification published by the Raspberry Pi Foundation.
Is the MCU of the Monarco HAT meant for running my own algorithms?
No, the internal MCU of the Monarco HAT only handles the input and output signals and communicates with the Raspberry Pi, the one and only "brain" to run your algorithms.
How does the Monarco HAT communicate with the Raspberry Pi?
Monarco HAT is connected via SPI and it also contains a few I2C devices onboard. RS-485 bus occupies the UART of the Raspberry Pi but it can be disabled. See the full technical specification of the Monarco HAT and the Monarco HAT documentation on GitHub for details.
Can I still use the GPIO pins of the Raspberry Pi?
Apart from SPI-0, UART, I2C-0 and I2C-1, the only GPIO pins occupied by the Monarco HAT are GPIO20, GPIO21 and GPIO26. You are free to use the remaining GPIO pins of the Raspberry Pi. See the full technical specification of the Monarco HAT and the Monarco HAT documentation on GitHub for details.
