Q1:PWR_IN & SERVO_PWR 

A1:

1.The power supply of the digital pin is connected to SERVO_PWR, and SERVO_PWR supplies 5~12V. After the servo power input interface is powered, it can only power the D0 to D13 digital pin, but not the board. If the program burned in the board needs to run, the board must be connected to the other power supply. PWR_IN is connected to vin, PWR_IN power supply 6~12V. The power supply of the I2C interface on the Shield is 5V. Use the 5V/3.3V jumper caps to select the power supply for the digital and analog pins.
