Review: Works perfectly. - Needed to swap a PNP to an NPN for a CNC project. Worked right out of the box and was simple to wire. Created a little 3D printed case for it to keep it clean and make it easy to mount.
Review: Perfect for Arduino and Geckodrive G540 - Works great to switch higher voltage logic signals with an Arduino. I'm using this on a CNC plasma cutter with an Arduino based torch height controller and Geckodrive G540. The G540 is powered by 24VDC and it's inputs are 12V logic active low. This module (5V->24V) allows the Arduino outputs to control the G540 inputs, and also provides an additional layer of isolation between the high voltage plasma source and the PC running Mach3

### ⭐⭐⭐⭐⭐ Works perfectly.

### ⭐⭐⭐⭐⭐ Perfect for Arduino and Geckodrive G540

Works great to switch higher voltage logic signals with an Arduino. I'm using this on a CNC plasma cutter with an Arduino based torch height controller and Geckodrive G540.

### ⭐⭐⭐⭐⭐ Worked perfect for my DIY CNC Machine
*by M***R on October 14, 2020*

Before adding this to my DIY Arduino based CNC machine I was having jobs constantly interrupted by noise on my limit switch inputs. Twisted shielded cables and capacitors helped, but the problem didn't go away until I added this between all my limit switches and the input pins on my CNC hardware. 4 channels is perfect for X, Y, Z and even the probe.
