Detail Explanation

LED “L” Here is an onboard LED in the expansion shield, it is connected to digital pin D&A Letter ’D’ and ‘A’ are printed in the Gravity IO Expansion & Motor Driver Shield
‘D’ stands for digital signal, which should be connected to digital pins.
‘A’ stands for analog signal, which should be connected to analog pins.

Gravity IO Expansion & Motor Driver Shield V1.0 is sufficient in interfaces. Compared to limited power supply interfaces in the control shields, it equipped with more GND interfaces and power supply interfaces. Although a multi-sensors connection, no need to worry about interface shortage. A row of red pins and a row of black pins are below digital pins and analog pin. They are the expanding power supply interface. The red pins connect to the power supply VCC and the black pins connect to GND. DFRobot Colors Explanation
• Green Digital Signal
• Blue Analog Signal
• Red VCC
• Black GND

The reason why designed the order as Signal > VCC > GND is to correspond to sensors linear order, the design has improved the wiring efficiency. RUN/PROG The new expansion shield added switch ‘RUN’ and ‘Download’. When using controller such as Arduino UNO/ Mega, you may failed to download program because downloading and XBee would occupy the same serial port. Therefore, you should switch to ‘PROG’ in download and switch to ‘RUN’ in run.
