LED-Wiz on 12V circuit
<< < (3/3)
RandyT:

Maybe I can clear this up.  The older LED-Wiz was not able to mix voltages, as it shared a common connection to a diode in each of the driver chips.  If the +5v line was not connected to the board, and the USB 5v jumper was not used, any voltage up to 50v could be used. 

The current version has a separate connection (Bank Voltage terminals) to the internal diodes for each driver chip.  These are useful in protecting the drivers when inductive or loads are attached directly.  While it is probably possible to drive multiple voltages on any one bank when the Bank Voltage terminals are unused, we suggest using those connections and limiting one voltage level per output bank.
