Powering Options The ETU can be powered by the following different sources: (Light red: GND pin is not included on this pin header.) Risk of Damage the Board Components (no. 4 and no. 5) Do not supply 5 V on the 3.3 V pin (“Arduino pin header” and “breakout pins”). This could lead to damage on board components.

Powering Option 1 Module native USB connector The whole board can be powered over the USB connector. The whole board can be powered over the USB connector. The PAN9520 is still powered if the peripherals are deactivated over PER_EN. 3 Current measurement The current measurement pin header X13 can be used for powering the pin header PAN9520 only. Please note that GND must be connected via a different connector (e.g. X19 as shown below). For power supply, the pin 3V3 and the pin 5 V of the Arduino socket can be used. If the pin 5 V is used, it is recommended to set “5 V Sel.” to “input”. This...

Powering Option 5 Breakout pins 3 PAN9520 ETU Description For power supply, the pin 3.3 V and the pin 5 V of the breakout pin headers can be used. If the pin 5V is used, it is recommended to set “5 V Sel.” to “input”. This will add a diode into the supply path, which avoids problems when connecting USB cables. Default Boot Mode Workaround Please note that the described setting shall ensure that the default application Boot Mode is also entered directly after powering the board. This Default Mode is also set by the ESP32-S2, but does only work, if the device is already powered and then...
