Power Supply

The on-board power supply circuitry allows various power supply configurations.

The power source can be:

–

BUS

from USB (5V)

–

BUS

from USB (5V) through the current limiter

–

External power supply (from 6 to 12V) or 9V battery

The voltage output can be the direct power source, regulated at 5V or 3.3V.

The power supply selection is performed using the JP2, JP3, JP4 and JP5 jumpers.

The power supply can be turned on/off using the “power” switch (SW6). Once the power
is established, the power LED (D9) is lit.
