There are many way to drive motors, like driving motor via L29P chip.
is specialized driving chip for high power motor rolled out by ST
Company. It can drive DC motor, 2 phrase and 4 phrase stepper. Equally,
its driving current is up to 2A and its output ends adopt eight schottky
diodes for protecting.
Therefore, we design this shield with
stack design that can be inserted into UNO R3 board directly, greatly
reducing the technical difficulties on operation and driving motor.
external power supplies power for driving expansion board and UNO R3
board when driving shield is stacked on UNO R3, BAT is plugged in and
DIP switch is dialed to ON end.
The PH2.0-2P anti-inverse port prevents from the circuit damage and wrong motor direction due to wiring power inversely.
the same time, the driving expansion board comes with a 2.54mm female
header interface, which is also a serial communication interface,
compatible with commonly used Bluetooth module line sequences on the
market, such as HC-06 module and HM-10 module.
other sensors and modules easily, driver board comes with 3pcs XH-2.54mm
3P, 2 pcs XH-2.54mm 4P and one XH-2.54mm 5P anti-inverse ports.
Moreover, expansion board extends 2 digital ports, 2 analog interfaces
and 1 I2C communication port with a pitch of 2.54mm pins. And a reset
button facilitates reset processing any time.
shield can be connected directly four DC motors via jumper caps
connection. A1 and A2, B1 and B2 are in parallel connection. Eight
jumper caps decide the rotation direction of 4 motors, for instance, the
horizontal connection of two jumper caps on A1 motor is changed into
vertical connection, that leads the inverse rotation direction
