Paglalarawan
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/OGreen 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 circuitReplacing 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. SPECIFICATION Compatible with Arduino Mega 2560 R3 Microcontroller: ATmega2560 Operating Voltage: 5V Input Voltage (recommended): 7 ~ 12V Digital I/O Pins: 54 (of which 14 provide PWM output) Analog Input Pins: 16 DC Current per I/O Pin: 40 mA DC Current for 3.3V Pin: 50 mA Flash Memory: 256 KB of which 8 KB used by bootloader SRAM: 8 KB EEPROM: 4 KB Clock Speed: 16 MHz DOCUMENTS Mega v3.0 Schematic Mega v3.0 Layout Arduino Official Website Atmega 2560 datasheet Arduino IDE Language Reference
