Power supply

The smart robot employs two series 18650 batteries for power supply with input
voltage of 7.4V. The input voltage will be deal with the LM2596 regulator, and send
out to Arduino, Raspberry Pi and sensors.
!
For using external power supply, the input voltage should not beyond 12V.

AD sampling chip

Since the GPIO of raspberry Pi do not support AD function, AlphaBot smart robot
has an on-board 10-bit of 11 channel AD conversion chip for tracking line
application.。
