Description

✅

The Opto-Isolated 4-Channel MOSFET Driver Breakout Board is a reliable solution for safely interfacing low-voltage microcontrollers with high-power DC loads. Each of the four channels features an optocoupler for complete electrical isolation between control and load sides, providing enhanced protection for sensitive logic circuits.

This breakout board uses N-channel MOSFETs (such as IRF540, IRF520, or equivalent) capable of driving DC motors, solenoids, LEDs, relays, and other inductive or resistive loads up to several amps per channel. The board can be controlled using standard 3.3V or 5V logic levels, making it fully compatible with platforms like Arduino, Raspberry Pi, ESP8266, and ESP32.

With opto-isolation, this module is ideal for industrial control applications, where electrical noise, transients, or high voltages might pose a risk to your control system.

🔧 Features:

• 4 independent MOSFET driver channels

• Opto-isolated input per channel (e.g., PC817)

• Compatible with 3.3V and 5V logic

• High-current MOSFETs for switching loads (check your board’s specific MOSFET ratings)

• Input control via microcontroller digital pins

• Screw terminals for easy load wiring

• Onboard indicator LEDs for each channel

⚙️ Specifications (Typical):

• Input voltage: 3.3V–5V (logic side)

• Load voltage: up to 24V or higher depending on MOSFET used

• Load current: up to 2–5A per channel (check MOSFET and heat dissipation)

• Dimensions: Compact PCB with mounting holes

📦 Applications:

• Motor and actuator control

• Relay replacement in automation circuits

• Smart home systems

• Industrial control and PLC interfaces

• Isolated switching of high-power DC loads
