Arduino Mega 2560 R3 Compatible Board SMD Board CH340 Chip with USB Cable

Introduction:

Is a piece of Arduino MEGA 2560 R3 SMD Compatible Board as the core of the microcontroller development board, itself has 54 groups of digital I / O input/output (14 of which can do PWM output), 16 sets of analog than the input, four groups of UART (hardware serial ports), Using a 16 MHz crystal oscillator? With a bootloader, it is possible to download programs directly via USB without going through other external writers. The power supply section can be powered directly from the USB, or use an AC-to-DC adapter and a battery as an external power supply.
Because of the open-source code, and the use of Java concepts (cross-platform) C language development environment, the surrounding modules and applications of rapid growth. The main reason for attracting artists is the ability to quickly communicate with software such as Flash or Processing … to make multimedia interactive works. Development IDE interface based on the principle of open-source code, you can download free for use in the production, school teaching, motor control, interactive works, and so on.
