I also dont understand why we cant have full schematic and troubleshooting guides with these boards. Kind of like a tech manual.
We all know when one fails, its usually a part that costs pennies, maybe a buck n half. A good soldering iron, magnifying glass, some patience and they can be repaired.
I have repaired, in the past, my clark boards and BARC boards for under $.25 in parts. Mosfets, diodes, transitors, regulators, semiconductors, ect, should all be replaceable/repairable on these boards. Just my opinion..
Enjoy,
