[Description]
Mode switch (#8) can be positioned anywhere. (Mode switch only works in the built-in basic program)
-
Supply power to the input power terminal (#7). Make sure correct input voltage(7.4V or 12V) and correct
-
polarity.(GND and VCC)
Carefully insert the connector suitable for the selected communication. (#14 PWM / #15 TTL / #16 RS-485)
-
(For PWM connector (#14), refer to the page 6 to make sure correct polarity.)
Among the header pins (# 12), the right three are analog terminals, and these three pins are used for Extra IO.
