### ⭐⭐⭐⭐⭐ CNC router noise isolation
*by Y***S on 24 May 2023*

Was getting feed back on my arduino uno from the end stop sensors and alarming up as soon as I started the router. Put this module in and working great. Would recommend for noise isolation and false triggers. Have 24 volt inductive sensors switching to 5 volts onto the arduino inputs through the module.
