I got the same problem supplying 12V to power my stepper motor. *Built-in 5v power supply, when the driving voltage is 7v-35v

Logical current: 0-36mA Drive current: 2A (MAX single bridge).

Logical voltage: 5V Drive voltage: 5V-35V.

EnB: Enables PWM signal for Motor B (Please see the 'Arduino Sketch Considerations' section).

EnA: Enables PWM signal for Motor A (Please see the 'Arduino Sketch Considerations' section).

5v: 5v input ( unnecessary if your power source is 7v-35v, if the power source is 7v-35v then it can act as a 5v out).

Out 4: Mo ( Can actually be from 5v-35v, just marked as 12v).

Motors will last much longer and be more reliable if controlled through PWM. The longer the pulses the faster the wheel will turn, the shorter the pulses, the slower the water wheel will turn. Take the water wheel analogy and think of the water hitting it in pulses but at a constant flow.

Motors are rated at certain voltages and can be damaged if the voltage is applied to heavily or if it is dropped quickly to slow the motor down. The voltage would be the water flowing over the wheel at a constant rate, the more water flowing the higher the voltage.

In motors try to imagine the brush as a water wheel and electrons as a the flowing droplets of water. * Pulse Width Modulation is a means in controlling the duration of an electronic pulse. That said we are always willing to help people to make parts as everyone benefits from more people willing and able to make parts.H-Bridge's are typically used in controlling motors speed and direction, but can be used for other projects such as driving the brightness of certain lighting projects such as high powered LED arrays.Īn H-Bridge is a circuit that can drive a current in either polarity and be controlled by *Pulse Width Modulation (PWM). To create the part yourself, these two sets of tutorials apply to the current versions of Fritzing (most of the others are for older versions of the software.) Using Eagle2Fritzing is more difficult yet (for starters you need a Fritzing development environment to build Eagle2Fritzing!) If you need a small number of parts, it is easier to convince one of us that know parts making to make them for you. To use directly for the breadboard view of the part, the image needs to be svg format, with proper scaling. The web page for ordering the part could have a “technical details” section with the needed details. That appears to be an Ardunio Uno style shields, but that still needs details about all of the additional pins. It needs a data sheet that shows the function and location of each of the connection pins. It takes more than an image to create a part.
