Adafruit MOSFET Driver - For Motors, Solenoids, LEDs, etc
We have ✅ 1 available of the AF-5648 in our Sydney warehouse. An extra 100 units available with a short lead time.
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
Ideal For
