The Adafruit STEMMA MOSFET Driver makes it safe and simple to control motors, solenoids, high-power LEDs, and other current-hungry loads from any microcontroller. Instead of wiring up a transistor and flyback diode on a breadboard, this compact board has everything built in — just connect power, signal, and your load.

At the heart of the board is an AO3406 N-Channel MOSFET rated for 30 V, 3.6 A peak, with a low 70 mΩ on-resistance, paired with a 1N4007 flyback diode for inductive load protection. The STEMMA JST PH input connector provides solderless hookup, and the logic input accepts 3–20 V signal levels.

Key Features

  • AO3406 N-Channel MOSFET – 30 V drain-source, 3.6 A peak, 70 mΩ RdsOn
  • Built-In Flyback Diode – 1N4007 protects against inductive kickback from motors and solenoids
  • Wide Power Range – 3–30 V load voltage
  • Wide Logic Range – 3–20 V signal input (works with 3.3 V and 5 V microcontrollers)
  • STEMMA JST PH Connector – Solderless 2-pin input for signal and ground
  • Screw Terminal Outputs – Two terminal blocks for power in and switched load out
  • Breakout Header – Optional 0.1" header pads for breadboard use
  • Continuous Current – Up to 1.5 A continuous, 3 A peak
Note: The JST PH connector is rated for 2 A continuous. For loads exceeding 2 A, use the screw terminals and breakout header instead.

Ideal For

  • Driving DC motors, fans, and solenoids from microcontrollers
  • Switching high-power LEDs and single-colour LED strips
  • Beginner-friendly projects that need safe high-current switching
  • Replacing breadboard transistor + diode circuits

Package Contents

  • 1× Adafruit STEMMA MOSFET Driver (assembled)
