2.4 Power Sources

Two options are available to power up the baseboard:
  • USB powering through the USB Micro-AB connector (J17 - default configuration)
  • Powering through the USB Micro-AB connector on the J-Link-OB Embedded Debugger interface (J10)

The two power sources can coexist. A priority mechanism manages the automatic switching between the two. The priority source is J-Link (J10), the secondary source is the USB port (J17).
