Freetronics FreeNFET Addressable 3x N-MOSFET Module

These are FETs with a brain! Includes 3 x NTD5867NL N-channel MOSFETs and a WS2811 addressable LED driver. That means you can connect the module and address it just as if it was a NeoPixel or other WS28xx RGB LED, except that instead of controlling an LED, you're controlling 3 high-power MOSFETs.

This smart module can be daisy-chained, so you can connect a number of these together in a string and drive each of them individually from your microcontroller.

Compatible with various Arduino libraries for the WS2811, including the FastLED library and the NeoPixel library. Simply control the "red", "green", and "blue" channels to control the FETs.


  • Switch up to 60V / 18A DC per FET.
  • Requires just 1 data connection.
  • PWM control of the FETs.
  • Input and output headers on opposite sides of the board for easy daisy-chaining.
