™

v7 contains two

additional pairs of screw

terminals which can be used

to get power supply output

for your external devices.

There are two available

output voltages: 5V and

3.3V. Depending on which power

source you use (adapter, laboratory

power supply, or USB), maximum output

currents can vary. Power consumption of the on-

board modules can also aect maximum output power

which can be drawn out of the screw terminals. Big power

consumers, such as Ethernet, or even GLCD with backlight

can alone drastically reduce the maximum output power. On-board

switching power supply can give maximum of 600mA of current if used

with adapter or laboratory power supply. When used with USB

power supply it can give no more than 500mA.

Purpose of the output voltage terminals is not to be the main power source of big

consumers, but more a power source for remote small consumers.
