<![CDATA[[Product] Core Stack Module: USB-C PD (as HV source and 5v system power step down)]]>A Core Stack module that can accept power via USB-C PD, controlled via I2C and dip switches, with option to route power over HV.
On board 5v regulator to supply system power from USB-C input.
Connector for external use of USB-C PD power.

Dip switches could be:
1: Off = HV Disconnected, On = HV Connected to USB-C PD Output
3 other dip switches:
000 = I2C Mode (full PPS control)
001 = 5V
010 = 9V
011 = 15V
100 = 20V
101 = 28V
110 = 36V
111 = 48V

For Atom and Stick too. But ideally, the module would buck 5V to the controller and the controller would be able to set the output voltage of the HV circuit.

I'd also love to see a charge regulator/BMS module you could plug lipo cells directly into to form 2S, 3S, 4S... circuits.
