In version 1.2, the ID EEPROM's Write pin is connected to ground, which consistenly enables the EEPROM to be able to be overwritten and could lead to accidental overwriting of the 'Hat' information. This should be protected by using a pull-up resistor to the +3v3 power and, for example, a jumper to GND.
