Works exactly as described. In my case, I'm using a PWM signal from a Raspberry Pi to drive an LED light strip at 24VDC for my FDM printer.

Really nice product. Works as advertised. The modules come in one slab (3 across, 2 down) and must be broken apart. If 3 in a row could be left together that would be handy - e.g. for driving an RGB string - but the terminal blocks are too close together between boards. Also, mounting holes on the terminal block end would be ideal. For prototyping on a breadboard I bent an extended male header to 90 degrees (a standard 90 deg header is too short) and soldered to the bottom (input/gate and source) and attached a jumper/lead to the drain. Keep in mind that the input is not directly connected to the gate(s) of the MOSFETs so will not drive like just a regular MOSFET. The LED indicator is great to let you know if the device is active. I highly recommend.

… is very annoying to find out that they come all together included in one single pcb board and you have to split them. That’s why is 4 stars and not 5.

Does what it says period.
