Want to make a robot, CNC machine, or 3D printer on an Arduino? Your microcontroller alone will not be able to turn the motors even a single degree. This Motor Shield Plus expansion board will help you connect DC and stepper motors with ease.
The motor driver is based on dual-channel H-bridge L6206Q which uses field effect transistors. The chip can withstand a pair of DC motors with a supply voltage from 8 to 52 V and a current of up to 2.5 A. Independent channels can be combined to drive a stepper motor with the same power ratings.
We have also added the ability to determine the current drawn by the motors. This will not only prolong the life of the motors, but also save device battery life.
This board is placed on top of the control platform using the sandwich method.
For communication with the microcontroller, these digital contacts are used:
|Purpose||Channel 1||Channel 2|
|Speed||5 (PWM)||6 (PWM)|
|Current Draw||A0 (ADC)||A1 (ADC)|
The pins are connected via jumpers. If your device pins are already taken, remove the jumper and connect to a free pin on the control board.
The board has two voltage lines:
If there is no current in at least one circuit, the Motor Shield will not work.
The platform provides the possibility of joining power sources. Place a jumper to power the control platform and the power unit from the same source.
For your convenience, LED indicators are located on the Motor Shield which show:
