Frequently Asked Questions

What is the primary function of the Wittelb PIHAT-8DO-MOSFET?

The Wittelb PIHAT-8DO-MOSFET is an expansion board for Raspberry Pi 4 and CM4, providing eight P-channel MOSFET digital outputs. It allows the Raspberry Pi to control higher voltage (12-24V DC) and higher current (up to 2A per channel) loads with solid-state reliability and fast switching, crucial for industrial automation and embedded control applications.

What is the maximum load current and voltage per channel?

Each of the eight channels on the Wittelb PIHAT-8DO-MOSFET can continuously handle a maximum load current of 2 Amperes. The board supports a switching voltage range from 12V to 24V DC. This makes it suitable for interfacing with common industrial actuators like solenoids, small motors, and indicator lights.

Is this HAT compatible with all Raspberry Pi models?

This specific PIHAT is designed for optimal compatibility with the Raspberry Pi 4 and the Raspberry Pi Compute Module 4 (CM4). While it might physically fit other models, its intended functionality and driver support are primarily geared towards these two platforms, ensuring proper GPIO mapping and power delivery for reliable operation.

What type of switching does the MOSFET offer and why is it beneficial?

The HAT utilizes P-channel MOSFETs for high-side solid-state switching. This means the output switches the positive supply to the load. High-side switching is beneficial in many industrial applications for fault detection, easier grounding of the load, and protection against short circuits, enhancing overall system reliability and safety compared to low-side switching.
