오리지널 아두이노의 성능은 그대로, 하지만 가격은 저렴하게!

• 오리지널 아두이노 메가 2560 R3보드와 성능은 동일
• 오리지널 보드와 사용법이 동일
• 오리지널 가격의 50% 이하 초저가

최신 버전 아두이노 메가 2560 R3 호환보드입니다.  사용법이 정품 아두이노 메가 2560 R3와 완전히 동일합니다.  드라이버 설치방법 및 아두이노 SW에서 보드종류 설정을 아두이노 메가 2560과  동일하게 설정한 뒤 사용하시면 됩니다.

알림. 아두이노(Arduino)팀은 아두이노 보드 설계도를 공개하고 누구든 자유롭게 호환보드를 만들수 있도록 허용하였습니다. 다만 Arduino라는 브랜드 명은 사용할 수 없도록 제한하고 있습니다.  시중에 공식 아두이노팀에서 제작하지 않았지만 Arduino 보드와 동일한 디자인과 상표명을 차용하는 제품들은 이를 위반한 제품인점 참고하시기 바랍니다.

DESCRIPTION

NEW VERSION! This is the upgraded DFRduino Mega 2560 V3.0 which is now fully compatible with Arduino Mega 2560 R3. The Arduino Mega 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; 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 Arduino Duemilanove, Diecimila or Uno.

One cool thing about our DFRduino microcontrollers is that the hearders with different colors are used to differentiate I/O ports in an relatively easy way:

• • Red indicates Power Section
• • Blue indicates Analog I/O
• • Green indicates Digital I/O.

This kind of correspondence match exactly the same with our sensors, making it even cooler and more user-friendly.

The R3 board enjoys following new features:

• • Added SDA and SCL pins that are close to AREF pin and two other new pins close to RESET pin, allowing voltage adaptation with IOREF. Our shields will be fully compatible both with the AVR boards operating @5V and Due @3.3V in future.
• • Improved RESET circuit
• • Replacing the Atmega 8U2 with Atmega 16U2 (datasheet)

Version history:

• • V3.1 - Choose the quartz crystals resonator to improve the timer and serial accuracy. Compared with ceramic crystals, quartz crystals get better temperature stability.
