This will be difficult . I can pull at most 4mA at 3.3V on the control
lines out of the uC board. That is not a lot of power.... I'm already at
over half of that, so realistically ... I can't pull more than 3mA with
a bit of safety factor.
How about using the input power to the 3.3 Volt regulator, 6, 10 or
12 Volts?
If anyone has one ideas please share.
