You can stuff the Rev 1 board exactly as it is. It is correct.

The first run was the prototype run - only 10 boards. The second run dealt
with some minor errors. Not many of these were made either. Rev 1 covered
more errors and Nyle's suggestions, and is the bulk of the PCBs that have
been made.

yes.

No. The 10 uF in question was replaced by a 1uF in Nyle's revision. The 1uF
is the correct way on the PCB.

just stuff away.
