Chapter 3.Power Supply
3.1.Requirements
This CPU board operates from a 5V power supply (supplied).
A diode provides reverse polarity protection only if a current limiting power supply is used.
All CPU boards have an optional centre positive supply connector using a 2.0mm barrel power jack.
Warning
The CPU board is neither under not over voltage protected. Use a centre positive supply for this board.
3.2.Power – Up Behaviour
When the RSK is purchased the CPU board has the ‘Release’ or stand alone code from the example tutorial code pre-programmed into the
Renesas microcontroller. On powering up the board the user LEDs will start to flash. Switch 2 will cause the LEDs to flash at a rate
controlled by the potentiometer.
