I have consulted this forum a lot as a reader, but this is my first post, so: Hello everyone!
Although I am not completely new to the raspberry pi, this is now my first electronic project.
The plan is (among other things) to be able to dim four strong LED strips (24 volts) individually. I have done my share of research and decided to control them with the raspberry pis software pwm and a MOSFET setup.
I found this four channel MOFSET which seems to do exactly what I need:

My question: as this board was developed for arduino and arduino supplies its GPIOs with 5V i was wondering if the raspberry pi with its 3.3V can switch these MOFSETS efficiently/completely.
Has anyone here experience with the 4-channel switch? Or is someone able to read the electronic scheme and documentation that are provided at the site and to tell me whether this board would work also at 3.3V? Or finally, do you know suitable alternatives?
Thanks a lot!
