MOSFET, Voltage, Current and VR Modules

Home | MOSFET, Voltage, Current and VR Modules

MOSFET, voltage, current, and variable resistor modules handle power switching, regulation, and measurement tasks that go beyond the direct output capabilities of a microcontroller. They act as the interface between low-power logic signals and higher-power loads or precise analogue measurements.

The range includes logic-level MOSFET switching modules for controlling high-current DC loads, voltage regulator modules, INA219 and ACS712 current sensor breakouts, and digital potentiometer modules for variable resistance control.

These modules are used in high-power LED dimming, solenoid and pump switching, battery monitoring circuits, motor speed control, variable power supply builds, load testing, and any Arduino or ESP32 project that needs to measure or switch currents beyond GPIO capability.
