2. Power Supply
2.1 Requirements
This board has an optional centre-positive supply connector using a 2.0mm barrel power jack (PWR). The
main power supply connected to PWR should supply a minimum of 10W to ensure full functionality. When the
board is connected to another system then that system should supply power to the board.
This CPU board supports one external voltage input. Details of the external power supply connection are
shown in
Table 2-1 and Table 2-2
below. The default power configuration is shown in
bold, blue text.

2.2 Power-Up Behaviour
When the RSK+ is purchased, the RSK+ board has the ‘Release’ build of the example tutorial software pre-
programmed into the Renesas microcontroller. Please consult the ‘Renesas Starter Kit+ Smart Configurator
Tutorial Manual’ for further information of this example.
There are RSK+ products which supports the 12V voltage input. Since this board is supporting the 5V voltage input,
be careful not to connect the power supply of a high-voltage output accidentally.
Moreover, the main power supply connected to PWR should supply a minimum of 10W to ensure full functionality.
