DC Power Connector Internal
The KTT30/mITX board has a power input voltage range from +4.5V to +5.5V. The power supply is connected
via the connector J17 (4 pin Micro-Fit) or alternatively the external Power connector J2 (3 pins, DC power
jacket 2.1mm). Notice that the +5V power lines on J2 and on J17 are connected on the board.

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.
