JP4 [9-10]: CN17 5V_CHG PWR SOURCE
Note:
With this JP4 configuration: 5V_CHG, the USB_PWR protection is bypassed. Never use this configuration with a
computer connected instead of the charger, because as the USB_PWR_protection is bypassed, and if the board
consumption is more than 500mA, this can damage the computer. If a 500 mA current is enough, it is
recommended to prefer the 5V_STLK source instead of the 5V_CHG source.

5V_DC power source
5V_DC is the DC power coming from external (5V DC power from CN5 pin5 ARDUINO
®
or from JP4 pin 2, 4, 6,
8, or 10 jumper connectors. In this case, the JP4 jumper must be OFF.
5V_DC power source configuration for jumper JP4 [-] is described in
.
