An old modul to the left and two new moduls to the right – I thought my old module was small…
This is the first run on this series so the main issue right now is mechanical design + correcting bugs – don’t worry, I have found some already – mechanical ones, but that is as expected. But, as far as I can see this looks good – very good. I will solder on some connectors and fit a box later so you can see.
A very annoying bug is that I use a M12-2 as power input, the footprint was modified from a M12-4 and I got it wrong as the real M12-2 used two different pins. Below I have modified a M12-4 just for testing.
The second bug is that I have put C30 to close to the connector – this will be ok, but I will move it on the next version.
This is very classic for a first run on boards – I expect errors to pop up as I populate the boards, so I push for a quick first round on everything so I can get errors corrected and move on to first poduction series. I will not list every bug here because that will be booring reading, but in a week or two I will order revisions as well as new boards. What I can say so far is that the main concept is working out fine. That said – I see many details that I suspect need to be changed, but that is the essense of engineering.
