3.0 BOARD DESCRIPTION
4.0 SPECIFICATIONS
4.1 Power Requirements
It requires a +5VDC@200mA or +7-24V@200mA external power supply or voltage
supplied by the RJ45 to operate.
WARNING
Check the polarity and voltage of the external power source and connect the 5V and
GND. Overvoltage or reverse-polarity power applied to these terminals can cause
damage to the board, and/or the power source.
