Arduino Shields

Make your project dreams come true: an odometer for the hamster wheel, a fully automatic control of your ant farm with web interface, or the Sandwich-O-Mat – a machine that toasts and grills sandwiches of your choice. With the Arduino and the DIY or Maker movement, not only did entry into microcontroller programming become child's play, but a second development also took place: Resourceful developers brought small boards – so-called shields or modules – to the market, which greatly simplified the use of additional hardware. The small modules contain all the important electronic parts to be connected to the microcontroller with a few plug-in cables, eliminating the need for a fiddly and time-consuming assembly on the plug-in board. In addition, it is also possible to handle tiny components that do not have any connecting legs (so-called SMDs).

You can control the motor driver with PWM and DIR inputs. The Arduino pins for these inputs are configurable via jumpers. If the specified pins on Arduino are already used up by other application/shield, you can select another pin easily with the jumper. There is also a possibility to quickly and conveniently test the functionality of the motor driver with the onboard test buttons and output LEDs. Buck regulator which produces 5 V output is also available to power the Arduino mainboard, which eliminates the need of extra power supply for the Arduino mainboard. The board also offers various protection features. Overcurrent protection prevents the motor driver from damage when the motor stalls or an oversized motor is hooked up. When the motor is trying to draw current more than what the motor driver can support, the motor current will be limited at the maximum threshold. Assisted by temperature protection, the maximum current limiting threshold is determined by the board temperature. The higher the board temperature, the lower the current limiting threshold. As a result, the motor driver delivers its full potential depending on the current conditions without damaging any MOSFETs. Features Shield for Arduino form factor Bidirectional control for two brushed DC motors Control one unipolar/bipolar stepper motor Operating Voltage: DC 7 V to 30 V Maximum Motor Current: 10 A continuous, 30 A peak Buck regulator to produce 5 V output (500 mA max) Buttons for quick testing LEDs for motor output state Selectable Arduino pins for PWM/DIR inputs.
