VIN (VIN_5V) is the 7 to 12 V DC power source from the ARDUINO
morpho connector (CN7) pin 24. The 5V jumper selection (JP3) must be on pin [3‑4] to select the VIN_5V power
source. In that case, the DC power can come from the ARDUINO
®
Adafruit PowerBoost 500 shield).
An LDO (U16) is used to provide a fixed 5 V from VIN (7-12 V).
VIN_5V configuration: 5V jumper selection (JP3) [3-4] must be connected as shown in
