PCB's have been ordered, so I'm hoping to have the first version built in a week or so. I made some small changes to the original design. One was swapping out the SOD523 package blocking diodes for a little larger SOD323 schottky. The advantage of this is it'll be easier for people who want to hand solder these to do so. Between the low parts count and the larger 0805 surface mount parts, I'm hoping these might be a good candidate project for people who want to practice surface mount soldering.
