Besides all kinds of sensors, the most important one in the electronic project is the master control. It's like the brain in human body, or the CPU in a computer. Arduino, Raspberry Pie, and MicroBits are common and popular controller boards. You can write code in IDE on a computer and download it to controller board through USB cable. As long as there is a power supply, the controller board can independently run the code inside.
Carduino is the controller board of Longan Cards, named after the word card and a nod to Arduino. As the name implies, Carduino is available to work with Arduino IDE easily. Arduino-based code resources in the community are also available.
Carduino can perform a variety of operations, the most basic and commonly used one is logic IF. If condition A is satisfied, action B would be triggered. With rich input and output modules of Longan Cards , many functions and ideas can be realized. If the temperature is above 28℃, switch on the air condition. If someone approaches your door at night, turn on the lights and take a picture.
Carduino is the new development board belongs to the Longan Cards Family. As its name implies it is small as ½ of a credit card, thin, and light weight. Carduino is pluggable, which means you can plug it to one of the following boards.
At the Carduino’s heart is an ATmega32U4 microprocessor and powered with the Arduino Leonardo bootloader allows you to program it using the Arduino IDE. We have written some exciting Arduino libraries that lets you to quickly develop applications.
Longan Cards is a unique open source development platform designed by Longan Labs. As a plug and play development platform, Longan Cards allows you to quicky build wide array of prototypes and applications in no time. A full set of Arduino libraries and plenty of example codes are available to play with Longan Cards platform.

↑ 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.
