D4184 N-Channel MOSFET Control Module — 40A, PWM Compatible

D4184 N-Channel MOSFET Control Module — 40A, PWM Compatible

The D4184 MOSFET control module allows an Arduino digital or PWM pin to switch and control high-current DC loads up to 40A / 100V. Built around the D4184 N-channel MOSFET with a gate driver circuit, it accepts 3.3V or 5V logic signals directly from Arduino — no level shifter needed. Supports PWM speed control for motors and LED dimming.
