It is not recommended to apply an additional power supply to the V
DD
pin of X1 (3.3 V) when the board is
powered via USB, because the 3.3 V supply could drive against the on-board power supply. The V
DD
pin can be
used to power an external circuit. But care must be taken not to draw more current than 150 mA, which is the
maximum current the on-board voltage regulator can deliver. Aer power-up the Debug LED starts blinking. In
case there is connection to a PC with correctly installed drivers, the Debug LED will turn from blinking to
constant illumination.
2.2 Pin header connector
The pin headers X1 and X2 can be used to extend the evaluation board or to perform measurements on the
XMC1100. The order of pins available at X1 and X2 corresponds to the pinning schema of the XMC1100
microcontroller in the TSSOP-16 pin package. The pinning table is also printed onto the bottom side of the PCB
(depending on the version). The pin header X3 can be used to access directly the 3D magnetic sensor pins.
