WIN – PIHAT – 8 DO(MOSFET )

WIN-PIHAT-8DO(MOSFET): Product Overview

The WIN-PIHAT-8DO(MOSFET) by Augmatic Technologies is an 8-channel industrial expansion board for Raspberry Pi 4 and CM4. It utilizes High-Side P-Channel MOSFETs to provide reliable solid-state switching for industrial loads, offering superior speed and durability compared to traditional mechanical relays.

Key Features & Specifications

• Solid-State Switching: Features 8 independent P-MOSFET channels for virtually unlimited operational life.

• High Load Capacity: Supports up to 2A continuous current per channel at 12V–24V DC.

• High-Side Output: The output voltage reflects the input supply (e.g., 24V input results in 24V output).

• Fast Response: Rapid switching time of < 100 µs, ideal for high-speed automation.

• Built-in Protection: Each channel includes an integrated flyback diode to protect against inductive load spikes.

• Industrial Design: Operates within 0°C to 60°C and fits the standard 40-pin Raspberry Pi GPIO header.

How It Works

The board uses a BJT-to-MOSFET driver stage to interface with the Raspberry Pi safely:

1. GPIO HIGH: The Bipolar Transistor (BJT) pulls the MOSFET gate LOW, turning the channel ON and powering the load.

2. GPIO LOW: The MOSFET turns OFF, cutting power to the load.

This architecture provides level shifting and buffering, protecting the Raspberry Pi’s GPIO pins from high-voltage industrial loads.

Connectivity & Pin Mapping

The module connects via the 40-pin header and uses the following GPIO mapping:
