Grove - MOSFET (CJQ4435) / compare with relay

MOSFET - Metal Oxide Semiconductor Field Effect Transistor

With the Grove - MOSFET you can control projects with a higher voltage, for example 15 VDC, with a lower voltage, for example 5 V, on the microcontroller. The MOSFET is also a type of switch, but its switching frequency can reach up to 5 MHz, much faster than a normal mechanical relay. There are two screw terminals on the board. One for the external power source and the other for the device you want to control. When closed, the module passes the current from one end to the other. However, if the external power source is missing, your device can still draw power from the microcontroller via the Grove interface. 

MOSFET stands for Metal Oxide Semiconductor Field Effect Transistor and is used to switch or amplify voltages in circuits. The purpose of a MOSFET transistor is essentially to control the voltage/current flow between the source and drain. The operating principle differs depending on the MOSFET type.

What is Grove?

Grove facilitates connection, experimentation and simplifies the prototyping process. No jumpers or soldering are required. More than 300 Grove modules have been developed to cover a wide range of applications and fulfill a variety of requirements. Not only the hardware is open source, but also the software. Instructional PDF documents and a wiki are provided for Grove users (especially beginners). 

We offer various Grove Shields to enable connection to the Grove system with various microcontrollers.
