Think of it as a "breakout board for breakout boards." Instead of plugging your sensors (like a PIR motion sensor, ultrasonic sensor, or servo) directly into the Uno’s messy headers, you plug them into the shield. The shield stacks directly on top of your Arduino Uno.
The Bluetooth/APC220 port shares the hardware serial pins ( D0 and D1 ) with the USB interface. You must unplug the Bluetooth module from the shield whenever you upload a new sketch from your computer, or the upload will fail.

The V pins are isolated from the Arduino's 5V regulator and draw power exclusively from the external screw terminal. Use this when driving high-current components like servos. How to Connect Peripherals
