SparkFun MOSFET Power Switch and Buck Regulator - Low-Side - SparkFun COM-23979
The SparkFun MOSFET Power Switch and Buck Regulator combines two functionalities - it works as a step-down regulator and a low-voltage switch at the same time. It is equipped with an LMR14203 (buck regulator), configured for a 3.3V output, and an N-channel MOSFET transistor configured as a Low-Side Switch. This allows you to power your project with up to 12V / 10A while providing 3.3V to the logic part of the control board.

Product description: SparkFun MOSFET Power Switch and Buck Regulator - power switch and step-down converter - Low-Side - SparkFun COM-23979
The SparkFun MOSFET Power Switch and Buck Regulator combines two functionalities - it works simultaneously as a step-down regulator and a low-voltage switch . It is equipped with an LMR14203 (buck regulator) configured for a 3.3 V output, and an N-channel MOSFET (PSMN7R0-100BS) configured as a Low-Side Switch. This allows you to power your project with a voltage of up to 12 V / 10 A , while simultaneously providing 3.3 V to the logic part of the control board. The manufacturer has equipped the module with a number of interfaces and useful connectors through which you can connect the power supply to a selected microcontroller (Arduino, micro:bit or Raspberry Pi).
