Arduino Compatible Connector - Infineon XMC4800 IoT Amazon FreeRTOS Connectivity kit Manual

XMC4800 IoT Amazon FreeRTOS Connectivity kit WiFi with EtherCAT® Kit
For XMC4000 family
Hardware description
If the board is powered via a USB plug, it is not recommended to apply an additional 5 Volt power supply to one of the 5
Volt power pins (VDD5, 5 V) on the Arduino headers or mikroBUS™ socket, because there is no protection against
reverse current into the external power supply. These power pins can be used to power an external circuit, but care
must be taken not to draw more current than USB can deliver. A PC acting as a USB host can typically deliver up to 500
mA current. If higher currents are required and in order to avoid damage to the USB host, the use of an external USB
power supply which is able to deliver higher currents than 500 mA is strongly recommended.
After power-up the green DEBUG LED starts blinking. When there is a connection to a PC via the Debug USB plug X101
and the USB Debug Device drivers are installed on this PC, the DEBUG LED will turn from blinking to constant
illumination.
