4.2.1 Power Supply
4.2.1.1 Power supply configuration
The StarterKit provides two options for powering the board’s integrated circuits. It is possible to
supply the StarterKit by using the E1 Debugger or it is possible to supply the StarterKit by using
an external 12 Volt power supply.
With the default jumper setting (see 0) the StarterKit is configured to be power supplied by the E1
Debugger.
The operation of the LIN and the FlexRay interface is only possible by using an external 12 Volt
power supply.
When the board is supplied externally by 12 Volt, please choose the following jumper settings:
