This car is education, hobbies, Robotics Competition must yield.
ATmega328 changed from the original master ATmega32u4, with two serial ports, mirco USB direct programming.
The upper link with I2C Expansion Board (sold separately) and compatible with more Arduino expansion boards.
HMC5883L integrated electronic compass sensor for sensing the direction and trajectory. Removed the unusual Xbee interface, making the car more mini.
