Description:   Funduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It's intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments.     The main reason why people choose Funduino is that they can use Funduino Language to communicate with software such as Flash and Processing etc.quickly, in this way,  they can make more Multi-media interactive works. Specification:    The Funduino Mega 2560 is a microcontroller board based on the ATmega2560 .It has 54 digital input/output pins (of which 14 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. The Mega is compatible with most shields designed for the Funduino Duemilanove or Diecimila.   The power design:       Funduino Mega has two kinds of Power-supply system, USB provide power directly or depend on external power supply. The choice of power-supply is alternative. If you choose external power supply, you can use AC-to-DC Adapter or Batteries, the voltage range is 6V-12V, but if the voltage smaller than 6V, the voltage of I/O Interface may cannot reach 5V, so it become unstable. And if the voltage is more than 12V, the voltage stabilizer will refer to overheat protection, then it will damage the Funduino Mega. In this way, the recommended operation voltage is 6.5V-12V, power source is 7.5V or 9V.   Package includes:   1pcs Funduino Mega ATmega2560 USB board 1pcs usb cable     Kindly Reminder: As there are several part number on the title, kindly pls remark the part number you want when you send the email or make paypal.So that we can avoide make mistake.Thank you very much!
