Product overview
This module allows any digital circuit or microcontroller with 5 V DC outputs to easily switch high
current DC loads. It can be used to drive loads such as high power LEDs, heaters, motors,
solenoids, etc… (it is recommended to add freewheeling diodes when switching inductive loads
like motors and solenoids). The module uses 3 high current IRF540NS MOSFETs to safely and
efficiently switch these loads on and off.
Note that the MOSFETs input pins (gates) need at least 5 V DC to properly switch on. Level shifting
will be required when using 3.3 V signals.
