EvalBoard description
The evaluation board (EvalBoard) is a ready-to-use printed circuit board (PCB) which contains:
•
The 3D magnetic sensor TLE493D-A2B6. For the availability of 3D Magnetic Sensor 2 Go kits with different
sensor variants check the Infineon web page:

•
XMC1100 microcontroller based on ARM Cortex
™
-M0 at 48 MHz frequency connected to the 3D sensor.
•
XMC4200 microcontroller based on ARM Cortex
™
-M4 at 144 MHz frequency used for debugging and USB
communication.
•
Micro USB connector for power supply and communication with the Graphical User Interface (GUI).
•
LED for indication of power supply and debugging.
•
Two LEDs for user configuration.
•
Voltage regulator, reverse current protection diode and ESD protection diode.
•
Pin headers to access data lines (e.g. via oscilloscope, external microcontroller).
The different components and its location are shown in
. The 3D magnetic sensor can be separated
from the rest of the EvalBoard by cutting the break line.

Optional external power supply
The 3D Magnetic Sensor 2 Go EvalBoard is supplied via the USB cable. It is also possible to provide an external
power supply. If this is the case, a few considerations must be taken into account as described below.
The 3D Magnetic Sensor 2 Go EvalBoard must be supplied by external 5 Volt DC power supply connected to the
micro USB plug. The voltage regulator shifts the voltage level to 3.3 V for the microcontrollers and the 3D
magnetic sensor. The Power & Debug LED indicates that the presence of the generated 3.3 V supply voltage.
Out of the box with the pre-programmed application and the on-board debugger in operation the EvalBoard
typically draws about 75 mA. This current can be delivered via the USB plug of a PC, which is specified to deliver
up to 500 mA. An on-board reverse current protection diode will ensure safe operation and protects the USB
port of the Laptop/PC in case power is provided through the pin header X1.
