External Power Supply

When the evaluation MCU is to have a desired power-supply voltage, or when more current is required, use
an external power supply. The usable voltages depend on the evaluation MCU.
Destinations for the connection of an external power supply:
•
VDD side: pin J6-16 or TP1 on the MCU header
•
GND side: pin J6-15 or TP2 on the MCU header
Figure 5-7 shows the positions of the external power supply.
When an external power supply is used, confirm that the I/O voltages for Arduino shields or Grove
modules are correct.
