MODULE MOSFET PWM 15A 400W

The 15A 400W MOSFET PWM Module (often labeled as the XY-MOS driver board) is a high-power electronic switch designed to control DC loads—such as motors, LED strips, solenoids, and heating elements—using low-voltage control signals from microcontrollers like Arduino, ESP32, or Raspberry Pi.

Key Technical Specifications

• Operating Voltage: DC 5V – 36V

• Continuous Current: 15A (at room temperature)

• Maximum Current: Up to 30A (requires added heat sinks or active cooling)

• Power Output: 400W max

• Trigger Signal Voltage: DC 3.3V – 20V (TTL logic compatible)

• PWM Frequency Range: 0 Hz – 20 kHz

• Switching Architecture: Dual parallel AOD4184A N-channel MOSFETs for lower internal resistance ($R_{DS(on)}$) and minimal heat generation.

Pinout & Connection Overview

• Trigger / Signal Side:

  • PWM / TRIG: Connect to your microcontroller's PWM output pin.

  • GND: Common ground connection with the microcontroller.

• Power Supply Side (Input):

  • VIN+ / VIN-: Connect to your main DC power supply (5V–36V).

• Load Side (Output):

  • OUT+ / OUT-: Connect directly to your load (e.g., motor or LED strip). Note: The module uses low-side switching, meaning it interrupts the negative line.

Common Applications

• Variable speed control for DC motors and micro water pumps

• Brightness control and dimming for 12V/24V high-power LED strips

• Pulse control for solenoids, heating elements, and DC valves
