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: pin J17-1 on the external power-supply header
•
VSS: pin J17-2 on the external power-supply header
•
Figure 5-8 shows the positions of the external power supply.
When an external power supply is used, confirm that the I/O voltages for Arduino
modules, or Grove modules are correct.
