Data Sheet

EtherDue
• Input Voltage: 7-12V DC recommended, 6-20V DC possible (onboard switchmode power
supply)
• Digital I/O pins: 54 (12 provide PWM output) (analog, CAN and CAN pins all also support
digital I/O, giving 70 digital I/O total if required)
• Analog Input Pins: 12
• Analog In Resolution: 12 bits, 0-4095 at 3.3V AREF is approx 0.8mV (0.0008V) per step
• Current Per I/O Pin: 24 mA source (output), 14 mA sink (input) current on most I/O pins. 9mA
on some others. See pinout diagram above for details
• Analog Output Pins: 2 DACs for true analog output
• Analog Out Resolution: 12 bits, 0-4095 is approx 0.8mV (0.0008V) per step
• Total Current For All I/O Pins: 130mA maximum
• Current At 3.3V: 800mA maximum
Memory
• Flash Memory: 512 KB Flash Memory
• SRAM: 96 KB SRAM in two banks, 64KB and 32KB
• microSD: microSD card slot with SPI interface. Uses pin D4 (chip select), SPI pins
Communications
• Serial: 4 x hardware USART serial ports, SPI (Serial Peripheral Interface), 2 x I2C ports
• Ethernet: 1 x 10/100 LAN port using the Wiznet W5100. Uses pins D10 (chip select), SPI pins.
• CANBus: 2 x CANBus ports
• USB 2.0 High Speed: "Native" High Speed USB port able to act as USB device (serial port,
mouse/keyboard) or USB host.
• USB Programming Port: "Programming" USB port connected to USB/Serial interface and serial
port 0 (RX/TX) for programming or serial communications.
• Other: Many other one-wire, multi-wire, LCD and expansion devices supported by free code
and libraries
