Anyone creating autonomous systems using the Raspberry Pi range of mini PCs might be interested in the new Multi-iO HAT specifically designed for Raspberry Pi automation. Compatible with all Raspberry Pi versions, from Raspberry Pi Zero to Raspberry Pi 5. This compatibility is achieved through the use of the I2C port, demonstrating the device’s adaptability and interoperability.
The Multi-iO HAT’s compatibility with all Raspberry Pi versions ensures that it can be integrated seamlessly into a variety of setups, offering a high degree of flexibility for users. Exclusive early bird pledges are now available for the interesting project from roughly $70 or £58 (depending on current exchange rates).
Raspberry Pi HAT
In terms of functionality, the Multi-iO HAT is equipped with multiple digital and analog inputs and outputs. This includes two opto-isolated or four common ground digital inputs, two 0-10V and two 4-20mA analog inputs and outputs. The device also features two 3-wire RTD ports with 24 bit delta-sigma A/D converters, enabling accurate RTD measurement. This multitude of inputs and outputs allows the Multi-iO HAT to handle a wide range of tasks, making it a versatile tool in the field of automation.
Moreover, the HAT comes with two 5A/24V relays with normal-open contacts and status LEDs. These relays enhance the device’s capabilities, allowing it to control various electrical circuits. The device also includes a H-Bridge PWM micro-motor driver and two servo control ports, further augmenting its function in automation processes.
Industrial Automation
The Multi-iO HAT stands out with its expandability to eight layers. This feature allows users to increase the IO capabilities of the device, making it suitable for more complex tasks. Up to eight Multi-iO HATs can be stacked on top of each Raspberry Pi, demonstrating the device’s scalability.
If the Multi-iO HAT crowd funding campaign successfully raises its required pledge goal and the project completion progresses smoothly, worldwide shipping is expected to take place sometime around January 2024.
