USB power: STLK configuration: jumper JP2 [1-2] must be connected as showed in
Figure 9.
Figure 9. STLK power source
VIN is the 7 V to 12 V DC power from Arduino CN6 pin 8 named VIN on Arduino connector
silkscreen or from ST morpho connector CN7 pin 24. In this case JP2 jumper must be on
pins 3 and 4 to select VIN power source on silkscreen of JP2. In that case the DC power
comes from the power supply through the Arduino Uno V3 battery shield (compatible with
Adafruit PowerBoost 500 shield).
