Power supply

Figure 2
The XMC4800 IoT Amazon FreeRTOS Connectivity kit with EtherCAT® must be supplied by an external 5 volt DC
power supply connected to any of the micro USB plugs (X100, X101). Out of the box with the pre-programmed
EtherCAT® slave application and the on-board debug probe in operation, the XMC4800 IoT Amazon FreeRTOS
Connectivity kit with EtherCAT® typically draws about 440 mA in an EtherCAT® environment. This current can be
delivered via the USB plug of a PC, which is specified to deliver up to 500 mA. The green Power LED (VDD3.3) indicates
the presence of the generated 3.3 V supply voltage.
On-board reverse current protection diodes will ensure safe operation when power is provided through both USB plugs
at the same time. These protection diodes allows to use the on-board debug probe connected with a PC/Notebook via
X101 and a second host PC/Laptop connected with the XMC4800 IoT Amazon FreeRTOS Connectivity kit with
EtherCAT® via X100.
