AlphaBot, Bluetooth robot building kit for Arduino

This kit comes with controller board UNO PLUS, AlphaBot robotic platform (line tracking, obstacle avoidance, speed measuring, IR control), ultrasonic sensor, Bluetooth module, and a versatile Arduino accessory shield. While utilizing UNO PLUS as controller board, this kit is based on the Arduino software/hardware open source platform. Combined with the modular design, it's an ideal platform to get started with Arduino robot. UNO PLUS Features UNO PLUS is a development board compatible with the Arduino UNO R3, an improved & enhanced alternative solution for Arduino UNO R3. UNO PLUS Vs UNO R3：

	UNO PLUS	UNO R3	Remarks
Operating voltage	5V/3.3V	5V	Dual voltage level to support more shields
Reset	Lateral	Vertical	Lateral button is easier to use when connecting with shield
Bootloader switch	Yes	None	The board can be configured to run program immediately when power-up by the switch
USB connector	Micro USB	USB Type B	Micro connector is more commonly used, and shields won't be blocked anymore while connecting
DC jack	Low profile	Normal height	Shields won't be blocked anymore while connecting
Power output header	Yes	None	Providing 5V/3.3V power output OR common-grounding with other boards
3.3V power output	800mA Max	150mA Max	UNO PLUS features higher driving capability
Oscillator	Crystal oscillator	Ceramic resonator	Crystal oscillator is suit for applications where accurate clock reference is required
ADC channel	8	6	CFG used as ADC6 by configuration, and ADC7 from the Reserved PIN
Connecting with prototype breadboard	Supported	Not supported	Solder pads is provided for DIY interfaces to connecting with prototype breadboard
USB driver	Compatible with all main systems	Doesn't compatible with WIN7/WIN8 Express Edition	Driver will never failed to install thanks to the onboard FT232
Firmware fixing	Supported	Not supported	Firmware can be fixed by using the onboard FT232, no extra programmer is needed
