When you have a project that just needs more inputs, outputs & memory than the Duinotech Classic (Uno) can deliver, the MEGA has them in spades. And with 8x the program memory, you have the room to write much larger programs to take full advantage of the increased IO. Despite its elongated size, standard shields will still drop straight onto this board.Features:• Fully Arduino®and DuinoTECH Compatible• ATMega2560 Microcontroller• EEPROM: 4KB• Speed: 16MHZ• ATMega16u2 USB-Serial Chipset• IO: Digital IO: 54 pins (15 are configurable as Digital or PWM) PWM Capable: 15 pins Analogue Inputs: 16pins Serial Ports: 4 (1 is connected to on-board usb-Serial port)• Input Voltage: 5VDC Regulated via USB port or 5V pin 7-14VDC via Vin pin On-board regulator supplies 5V when unit is powered via Vin pin Specifications: Length 53mm Width 108mm Height 15mm Fully arduino compatible Yes Program memory 256MB Board Inputs 2 Board Outputs 4 USB Voltage Input 5V RAM 8GB DownloadsDownload Datasheet
