Banana PI BPI Q-Car,which is a robot focusing on maker education.Compatible with Web:Bit(BPI: Bit) and Micro:Bit development boards.Small car body, highly integrated functions, plug and play, can quickly children's attention, complete the quick start of graphics programming, cultivate independent thinking and logical thinking ability

==Key Features==
*support Micro:bit and PBI:bit(Web:bit)

*support Makecode graphical programming(with micro:bit)，support Webduino graphical programming（with BPI:bit）,and it also support MicroPython arduino（Micro:bit/BPI:bit）

*Compact body, strong integrity

*N20 Miniature reducer

*Infrared emission, infrared reception, line patrol, speed measurement, atmosphere lamp, I2C interface (support 3.3V and 5V), ultrasonic interface, buzzer, steering gear interface, needle row expansion port, expansion screw hole, etc...Fully functional, strong expansibility

*Easy to use it.
