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
