OK - more perusal shows that it's more subtle than this - R12 and R36 (or
U7) are only needed for the Audio power amp 5V and LCD 5V supply, neither of
which is used by most people. So in fact one can reasonably fit neither (as
we have been doing to date on 205g ('guralp') builds), which don't have the
power amp fitted anyway. USB 5V is supplied direct.
