Power requirements

By default, the ISP1301 board is powered by a +5.0 V power supply through the DC jack (J12, inner +). The +5.0 V
power can also be supplied from the USB Type-B connector (J4). However, when J4 is connected to a USB port
on the PC, leave the USB mini-AB connector (J9) unconnected. If an external microprocessor is used to control
2
the I C controller chip PCF8584 (U4), the +5.0 V power can also be supplied from pin 16 and pin 18 of the
microprocessor connector (J13).
When the +5.0 V power is correctly applied to the board, LED2 (green) will turn ON.
