Keyestudio 3-way Channel IRF540NS High Current MOS Tube Module for Arduino

The Keyestudio 3-way Channel IRF540NS High Current MOS Tube Module is a versatile switching board designed to control high-current loads using low-current microcontroller signals. It is an ideal choice for Arduino makers, students, and hobbyists who need a reliable alternative to mechanical relays for driving high-power components.

Three-channel high-current switching

This module uses three independent IRF540NS MOS switches to control high-current loads with small control currents, functioning similarly to a relay element. It is ideal for driving servos, high-current LED lights, and other demanding DC components.

Simple logic control and LED indicators

By setting the NA, NB, or NC control pins to HIGH or LOW, you can easily connect or disconnect the corresponding ground path. Onboard D1, D2, and D3 LEDs provide clear visual feedback by lighting up when a channel is active.

Flexible voltage routing

The module accepts an input voltage of less than 40V DC at the VIN and GND terminal blocks. The voltage at the V+ terminal block matches the VIN input, allowing for straightforward power distribution to your connected devices.

Easy physical integration

Designed with four pre-drilled 3mm fixing holes, this compact board can be securely mounted to your chassis, robot frame, or custom enclosure. This ensures stable installation in mobile robotics or high-vibration environments.

Technical specifications and ratings

Operating safely between -20 and +60 degrees Celsius, the board supports a working voltage under 40V DC and an operating current of less than 10A. It measures 66mm by 38mm by 12mm, weighs 22.8g, and is RoHS compliant.
