The Mosfetti by Monk Makes is a compact 4-channel MOSFET switch designed for maker projects. Each channel can drive up to 2 A of low-side switching at up to 16 V DC, making it perfect for controlling relays, solenoids, LED strips, pumps, and motors from a microcontroller.
Supplied as a PCB with surface-mount components pre-attached, plus header pins and screw terminals as a solder-it-yourself kit. Built-in flyback diodes on every channel protect against inductive load spikes, and a resettable polyfuse guards against overcurrent.
Key Features
- 4 Independent Channels – Low-side MOSFET switching, up to 2 A per channel
- Resettable Polyfuse – 2.5 A max total overcurrent protection
- Flyback Diodes – Built-in on each channel for inductive loads (motors, relays, solenoids, pumps)
- LED Indicators – Power LED plus individual channel status LEDs
- Up to 16 V DC – Suitable for a wide range of loads
- Kit Format – SMD components pre-soldered; header pins and screw terminals included for user assembly
Ideal For
- Driving LED strips, relays, and solenoids from Arduino or Raspberry Pi
- Model railroads and RC projects
- Irrigation pumps and automation
- Strobe lights and signalling
Jargon buster
Plain-language definitions for the technical terms used above.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
- PCB
- A printed circuit board is a rigid board with copper tracks that connect electronic parts without loose wires. For this kit, the PCBs also form the airplane shape, so they are both the circuit base and part of the finished model.
