+=== Power ===
+Power may be applied through the power jack or the power header. There are two LDOs and a jumper is used to select the MCU voltage between 3V3 or 5V. When applying 5V on the power header, the 3V3 LDO is still utilised so it may be selected.
+When using the power jack socket, the switch will turn the board on and off, as it
+feeds the 5V LDO.
+There is a VUSB selection jumper which may power this pin if the PIC internal regulator is disabled. For PICs that are not USB, remove the jumper and use this a method of accessing pin 14.
