Module heartbeat monitor with 15 inputs and LCD

As I started putting more and more modules into my rack box project, the previous monitoring module quickly ran out of inputs. I needed to build something bigger and better. I realized that using LEDs to show module status just wasn’t practical as the number of inputs increased. So this unit shows the module statuses on an LCD display instead, and has 15 inputs.


Module heartbeat monitor with 6 inputs

When my rack box project started filling up with modules, I needed (or rather wanted) a way of monitoring that they were running and doing what they were suppose to. I tried monitoring the fuses (1) (2), but that just wasn’t practical. I needed a way to know that the modules were not only powered, but running. This module does just that.
