One goal of this version is for it to work with the K3 solenoid driver board. The ADC inputs are now level shifted just like the digital IO so they can be used for either function. Each current source can be enabled/disabled so I can reduce power to very low levels if the power source is running low. Finally, the attempt to have a replacement for a solar charge controller function is found as an Alternate power input. The alternate input is a P-channel MOSFET that the microcontroller can enable to let power to the main line which is presumably connected to a battery. The alternate power input has only had basic testing done so I am not sure how useful it will be.
