Warning: Do not overload the onboard system voltage +3.3V resp. 1.8V (microSD TM card socket, digital I/O connector). The maxi-
mum current should not exceed 250mA.
Note: 1) To protect the external power lines of peripheral devices make sure that
- the wires have the right diameter to withstand the maximum available current.
- to enclosure of the peripheral device fulfills the fire-protecting conditions of IEC/EN 60950.
15.3 Default Power Configuration
In the delivery state the three short circuit jumpers are set (DC power jacket configuration). As far as
possible all three pins should be used (each VCC_IN and VCC) to minimize the current load per pin.
CAUTION!
If you use an external power supply do not use another voltage than +5V DC.
