The Arduino Due is a micro controller board based on the Atmel SAM3X8E ARM Cortex-M3 CPU.

The Arduino Due is a microcontroller board based on the Atmel SAM3X8E ARM Cortex-M3 CPU.

Unlike the "original" Arduinos it is not based on the 8-bit AVRs but on an 32-bit ARM Cortex. It has 54 digital input/output pins (of which 12 can be used as PWM outputs), 12 analog inputs, 4 UARTs (hardware serial ports), a 84 MHz clock, an USB OTG capable connection, 2 DAC (digital to analog), 2 TWI, a power jack, an SPI header, a JTAG header, a reset button and an erase button.

It runs on 3.3 V instead of 5 V. It has significantly higher computational power both due to the higer clock frequency as well as due to the bigger word width. In addition it has more memory 96k SRAM and 512k Flash. However it lacks any EEPROM. Also its current consumption is higher as compared to the AVR cores.

An overview can be found on the official Arduino Due pages. The official pages also provide schematic and board layout information.

Slow Arduino Serial Port on UDOO Quad

Using a UDOO Quad, I am attempting to push data from the Atmel SAM3X8E (Arduino side) to the Freescale i.MX 6 (Linux side) over the serial port as fast as possible. Currently, I am limited to about 10,000 bytes/second, which is plausible because the…
