Hive Interface Board

Design the next version of the Hive Interface board.

Background: http://hivetool.org/w/index.php?title=Change:_Interface_PCB

Split the current hive interface board in two, Board A and Board B.

Board A will be a general purpose interface board that meets the Pi HAT specifications and contains:
at least one 4 channel ADC so each load cell will be individually measured instead of being summed.
Real Time Clock with battery backup.
Configuration ROM
Power supply

Board B will have all the connectors installed in a bulkhead configuration. It will connect to Board A by directly plugging into a header on Board A or connect via a ribbon cable.

Design Considerations
Must have reliable serial communication to the Pi. Probably should use SPI, I2C bus.
Consider using 16 bit ADC instead of 24 bit.
