Description

SparkFun MOSFET Power Switch and Buck Regulator (Low-Side) – Power Control and Regulation in a Single Package
Are you working on projects where you need to control high-voltage devices like motors, LED lighting, or other power-hungry components, but also want to keep your microcontroller safe and powered? The SparkFun MOSFET Power Switch and Buck Regulator (Low-Side) solves this common challenge with elegance.
 
Effortless Project Power Management
This versatile board streamlines your electronics projects by integrating two essential functions:
  • Step-Down (Buck) Regulator: Converts your input voltage (4.5V to 12V) to a clean 3.3V output, ideal for powering microcontrollers like Arduino or Raspberry Pi boards.
  • Low-Side MOSFET Switch: Safely and easily controls high-current loads (up to 10A) directly from your microcontroller's digital pins.
Features for Safety and Convenience
  • Protection Built-In: The onboard flyback diode safeguards your project from damaging voltage spikes that can occur when driving inductive loads like motors.
  • Clear Visual Feedback: Two LEDs provide instant status updates on power availability (3.3V) and whether your load is active.
  • Customizable: Disable the LEDs with jumpers if needed in power-sensitive or light-sensitive applications.
  • Precise Measurements: The MEAS PTH jumper allows for accurate current monitoring.
Flexible and User-Friendly
Connect your power supply, microcontroller, and high-current device with ease using the board's various connectors: a standard barrel jack, female headers for control signals, and robust poke-home connectors for your load. For a more permanent setup, utilize the 0.1" spaced PTHs.
 
Perfect for Hobbyists, Educators, and Prototyping
The SparkFun MOSFET Power Switch and Buck Regulator (Low-Side) is an indispensable tool for:
  • Makers and Electronics Enthusiasts: Simplify your project wiring and reduce clutter.
  • STEM Education: Demonstrate power conversion and control principles hands-on.
  • Rapid Prototyping: Quickly test high-power components without complex power setups.
