Moisture Sensors Arrive

The circuit boards for my soil moisture sensors arrived yesterday. I ordered four panels with ten sensors each, for a total of forty sensors. I ended up receiving five panels—25% more than I ordered—at no additional cost.

I populated one sensor last night and put it thru a quick smoke test this morning. No smoke, and it seems to be working fine. Unfortunately I won't have time to populate any more until next week.

The carefully observant will notice that despite my previous claim that I had created the "final" layout weeks ago, the layout has indeed changed once again. It turned out the edge connector wasn't the best idea, so I've settled on a shrouded locking 3x2 right-angle header for the connector.
