adjust power design for 2 pins for 5V Voltage sensing #187

Closed nerdoug closed 2 years ago

nerdoug commented 2 years ago

To read the 5 Volt signal, we need a GPIO pin that enables the measurement circuitry (MOSFET) and A/D pin to read the input signal from the voltage divider. Need to change GPIO assignments, and update power control diagram.

As part of this we've committed to using a single measurement of 5V power.

Could also explore I2C devices that measure voltage to save GPIO pins.

Also made adjustments to GPIO-pins.ods to reflect changes needed for going to a single voltage monitor point for 5 Volts.
