Arduino Module 4-Ch Mosfet Switch

The Arduino Module 4-Ch Mosfet Switch is a four-channel MOSFET switching board that lets the low-power output pins of an Arduino, ESP32 or other microcontroller turn larger DC loads on and off. Each channel works independently, so one board can control up to four devices such as LED strips, small DC motors, pumps or solenoid valves, and PWM signals can be used for dimming or speed control.

Arduino Module 4-Ch Mosfet Switch Specifications

• Channels: 4 independent MOSFET switches
• Control: logic-level signals from microcontroller pins, one input per channel
• Load type: DC loads only
• Switching: solid-state and silent, with no moving contacts
• Control modes: on/off and PWM

Arduino Module 4-Ch Mosfet Switch Applications

• Switching and dimming 12 V LED strips
• Driving small DC motors, fans and pumps in one direction
• Controlling solenoid valves and electric locks
• Home automation and greenhouse projects
• Replacing noisy mechanical relays for DC loads

What's in the Box

• 1 × 4-channel MOSFET switch module

Tip: Connect the ground of the load power supply to the Arduino ground unless your board is opto-isolated, and fit a flyback diode across motors, solenoids and other inductive loads. Check the MOSFET part number printed on the board for its exact voltage and current limits.
