Does your project need to open and close a circuit with a large voltage or current? This mosfet from the Troyka module series is what you need. It’s easy to work with and extremely easy to use - no soldering, no small components, no confusion. Nothing needs to be set up, nor complicated FET eqations needed - everything is ready for you to use out of the box!
A microcontroller such as an Arduino can not directly control a powerful load. Its outputs can only give a tiny current, barely enough to power a small servo. If you want to manage a high-voltage/current load, such as an LED strip, water pump, or DC motor you need some kind of key to turn them on and off when not in use. This module is in effect just a key based on a powerful (MOSFET) transistor.
To solve your problem, you could use a relay, but the MOSFET has its advantages. It supports PWM, which means that you can adjust the speed of the motor or the brightness of the LED strip. However, unlike a relay, a MOSFET can only switch a DC current.
This module is based on the N-channel IRLR8113 FET. It is designed in such a way that it efficiently dissipates the heat generated during its operation. Meaning, the transistor will not fail from overheating.
The MOSFET closes when a logical 1 is fed to the input of the module. At the same time, it has a built in system which makes it possible to use any voltage signal from 3 to 5 volts. Therefore, this module can be controlled by most boards, including a Raspberry Pi
On the module there is a LED indicating the state of the transistor. It is lit when the transistor is on.
Connect the sensor via 3-pin jumper cable to receive a signal from the scanner. The 3-pin jumper cable needed for the connection is included in the kit.
There are several different ways to wire this module:
Troyka Shield. The most straightforward method. Connect the module to a pin group on Troyka Shield with the 3-pin jumper cable and you’re ready to interface with it from your Arduino.
Troyka Slot Shield. The best choice for quick prototyping. Using slots on the shield, you can get rid of cables. The module will be held securely in place using both pin headers.
Breadboard. For advanced use. Troyka pin headers have 0.1” spacing which is compatible with any breadboard. Simply wire the module like you would do with any IC.
Additionally, there is a screw terminal block to help guide your wires into the circuit.
