AS3935 Lightning Detector Breakout – Coming Soon!

Even before actual silicon was for sale, Michael and I have been wanting to try the AS3935 “Franklin Lightning Sensor™” from ams AG (formerly austriamicrosystems AG).  It comes in a very inconvenient MLPQ-16 package, and requires an on-board antenna, so it was a natural for a breakout board.  It’s been on the back burner for a few months, but I completed the PCB layout on Saturday and it went onto a panel this morning.  For those of you who, like us, can’t wait to experiment with this intriguingly unique part, we should have boards for sale within two weeks.  Price to be announced soon.

As we were installing them, it occurred to me that it might be nice to show folks how to reliably install MRServo, step by step.  The instruction sheet covers this all, but sometimes a picture really is worth a thousand words.  Once you get the hang of it, it’s quite easy and goes quickly.
