VIN (5V_VIN) is the 7 to 12 V DC power source from the ARDUINO
®
included Zio connector (CN8) pin 15 (VIN),
or from the ST morpho connector (CN11) pin 24. The 5V jumper selection (JP6) must be on pin [3-4] to select
the 5V_VIN power source. In that case, the DC power can come from the ARDUINO
®
Uno V3 battery shield
(compatible with the Adafruit PowerBoost 500 shield).
An LDO (U11) is used to provide a fixed 5 V from VIN (7-12V).
5V_VIN configuration: 5 V jumper selection (JP6) [3-4] must be connected as shown in Figure 10.
