The EDK hardware requires a power supply of +5V. Since total power consumption can vary widely due to external
connections, port states, and memory configuration, use a power supply capable of providing at least 500mA at +5V DC ±
5%.
The design is specified for evaluation of the microcontroller and so does not include circuitry for supply filtering/noise
reduction, under voltage protection, over current protection or reversed polarity protection. Caution should be used when
selecting and using a power supply.
The power connector on the EDK is a 2.5mm Barrel connector. The center pin is the positive connection.

Caution: Existing customers using E6000 products note that the polarity of this board is opposite to that for the
E6000. Use of the E6000 power supply with this board will damage both board and power supply.
