Update to the Milliohm Meter Project
Updated V1.5 board assembly for the Milliohm Meter Project.
The Milliohm Meter board V1.41 is featured in Scullcom’s Milliohm Meter Udpdate YouTube video.
I had already started on the version 1.5 board update a week earlier and was about to send the prototype files out to OSH Park for manufacturing, when I noticed a new Scullcom video thru my YouTube subscription notice. I was pleasantly surprised to see that it was an update to the original Milliohm Meter and it was featuring the V1.41 board that I had designed. Louis had made some similar updates to components, so I quickly updated the V1.5 board file to match before sending it off.
