I did a bet with myself whether this reply will come ;-)
The PCB is designed to run under different supply conditions: +12
eurorack, +5V eurorack, +8 - +12V wallwart, maybe even batteries. That
is why I don't have a defined "high power"-supply for the backlight, and
why I have to use the +5V which is the same for all kinds of supply.
