The motor converts electrical energy into mechanical kinetic energy according to the magnetic effect of current. For a DC motor, the speed of the motor varies with the input voltage. Tesla drives the motor and makes car move through electric energy of the battery. Motor Driver Card's main function is to control the speed and direction of the DC Motor through the circuit, so as to make mechanical car move forward and backward, speed up and down.
In addition, Motor Driver Card can also control the movement of the stepper motor. Stepper motor is based on the principle of electromagnet, in which the rotating structure can be quickly adjusted to a specific position within the range of angles. It is widely used in the design of robot kinematic joints and mechanical arms. Motor Driver Card helps you control the stepper motor circuits freely. By adjusting the frequency and number of pulse signal, it is allowed to control the speed and displacement of stepper motor, and achieve the required motion.
Motor Driver Card features LV8548MC, which is a 2-channel motor driver IC. It can drive two DC motors or one DC motor using the parallel connection, or it can drive a stepper motor in full-step and half-step.

↑ Longan Cards system consists of Cards and Boards. There are many gold finger antennas on Card and several gold finger sockets on Board. They are combined together through sockets interpolation, which is intuitive and easy to use. With this unified and flexible interface, you can realize a variety of ideas. Many more Boards with different themes would luanch to help people explore more fun.
↑ Longan Cards modules are classified into many types. Firstly, the main control cards which are the heart of Cards system, run the code and take charge of the exchange of data between modules. Besides Carduino, you can also use MicroBit, Arduino and other development board through connection board. The sensor cards can detect data of surrounding such as temperature and air pressure, etc. The inputs cards allows you to do some operations, such as buttons, knobs, etc. The output cards give feedback in various forms, such as buzzers, motor drives, etc. The communication cards can transmit data in many ways, such as Bluetooth and 4G network. The power cards supply power for electronic projects, including batteries, DC, etc. And other cards, mainly do some auxiliary work, such as expansion, code downloading, etc.
↑ STEM is an acronym for science, technology, engineering, and math. STEM education began in the United States in the 1990s. It is an interdisciplinary teaching method that combines STEM content and real life situations, which helps stimulate students’ original curiosity and thirst for knowledge and novelty. Longan Cards contains dozens of modules, involving a wide range of knowledge in the process of use, including electronic circuit, mechanical structurenature, programming, science of nature, daily wisdom, and humanities, etc. It is a powerful tool for STEM education at fields of electronic prototyping, science experimentation and DIY project.
