Expansion Shield X200 is a very cost-effective for Raspberry Pi Raspberry Pi Model B +, Raspberry Pi 2 Model B and the latest Raspberry Pi 3 Model B expansion board.
It combines vital functions such as RTC real time clock, audio input and output, self-powered USB hub, VGA output, WiFi wireless Internet access, 8-channel high current GPIO control.
We have it, so you can more easily use the Raspberry Pi Raspberry Pi and save you more valuable time and costs.

• Raspberry Pi Raspberry Pi board with the same size (85MM*56MM), mounted directly onto the motherboard raspberry pie, column nylon screws, no additional wire.
• High efficiency step-down DC / DC converter to the stability of the motherboard power supply, 6-21VDC input, 5V 3A maximum output, with microphone input and audio amplifier (power 3.3W x2) output interface.
• Support HDMI to VGA (without Raspberry Pi board HDMI interface, power supply), WiFi wireless Internet access, equipped with high-gain external antenna, supports infrared receiver (38KHz), supports microphone input and audio output, 3.5mm headphone jack and more convenient external headset.
• Eight GPIO control a large current to drive the load current of each channel up to 500MA, it has a power output port (5V, DC input voltage) to facilitate supply to other devices or expansion boards.
• Has a DIP switch can be disconnected from the Raspberry Pi connected to the motherboard using other expansion board has no effect, you can still connect to other expansion board by its pin.
