== {{:CW303 XMEGA Target/Solder Jumpers ==; SJ2: Selects the source of the input to the VCC filter - either the 20-pin 3.3V VCC (default), or the optional voltage regulator which derives the power from a USB-Micro connector.; SJ3: Connects the output of the VCC filter to the XMEGA VCC network. Soldered by default.; SJ4: Connects the SMA Measure header to the resistive shunt. Soldered by default.; SJ5: Connects the SMA Glitch header to the resistive shunt. Soldered by default.; SJ7: Connects the VCC of the XMEGA board to VREF on 20-pin header. Soldered by default.}}
