7V to 23V) or DC (in the range of 9V to 32V). Jumper J14 is used as a selector for a power supply source. To make advantage of the
USB power supply, jumper J14 should be placed in the USB position. When using external power supply, jumper J14 should be placed
in the EXT position. The development system is turned on/off by switching the position of the POWER SUPPLY switch.
