POWER SUPPLY
The EasyPIC5 can use one out of two power supply sources - PC
power supply over USB cable (by default) or external power supply
(external AC/DC power adapter). When using power supply over USB
cable, jumper J6 should be set in the right-hand position.
When using external power supply, the EasyPIC5 board produces
+5V using LM7805 voltage regulator. The external power supply can
be AC or DC, while its voltage ranges between 8 and 16V. In this case
jumper J6 should be set in the left-hand position. Figure 9 illustrates
USB and external power supply circuit diagram.
