| DC Micro Metal Gear Motor 75:1 w/Driver SKU DFR0399 Micro Metal DC Geared Motor w/Driver Contents • 1 Introduction • 2 Specification • 3 Motor Overview • 4 Tutorial Requirements Connection Diagram Sample Code Note Introduction An ordinary DC motor requires an H Bridge to work with a microcontroller such as an UNO. For newcomers to electronics, the process of finding the right motor driver, connecting it to the MCU and learning the relevant electronic theory can be confusing and frustrating when you just need something to work quickly. We hope that using the DC Micro Metal gear motor changes this. The new micro DC geared motor is easy to operate - using the DFRobot "Gravity" interface, you are able to control the motor using only one control signal. Easily implement forward/reverse control and speed control via PWM. This motor also combines the features of a DC motor and 360 degree servo. We have also increased the stop range and reduced standby power consumption, so the current draw is less than 1mA without signal control. Ideal for DIY projects! NOTE The embedded control chip will consume a small amount of the input voltage, therefore the motor voltage will be slightly reduced. The motor speed will also be slightly slower than the rated motor speed. Specification • Operating voltage 3.5V - 8V • Reduction ratio 75:1 • No load current approx • Static current <1mA no PWM control signal input • Interface Gravity 3-Pin • PPM signal resolution 1us • PPM signal pulse width range 500us-2500us • Clockwise pulse width range 500us-1400us 500us speed maximum • Stop pulse width range 1400us-1600us • Anticlockwise pulse width range 1600us-2500us speed maximum • PWM frequency 500 Hz. No. Label 1 Signal 2 Power Motor Overview Description PWM signal input - 3 GND DFR0399 Tutorial The motor works similar to a 360 degree rotation servo, using the servo library Arduino IDE included .
