Arduino® Board Due without headers

Classification Device CoreARM Cortex M3 Name Arduino Due Processor Family NameSAM3XE Processor Part NumberAtmel SAM3X8E Processor TypeCPU Arduino Due Development Boards The Arduino Due board features a 32-bit SAM3X8E ARM Cortex-M3 microcontroller and comes in two versions: 7697412 with headers and 8474888 without headers. To power up your Due board and get started, you can either connect it to a computer using a micro USB cable or use an AC-DC adaptor/battery. Unlike other Arduino boards, the Due can only be powered at 3.3 V. Features & Benefits of the Arduino Due •54 digital I/O pins (12 of which can be used as PWM outputs) •12 analog inputs •4 UARTs •84 MHz clock •96 kBytes of SRAM •512 kBytes of flash memory •DMA controller that supports the CPU with high memory tasks •USB On-The-Go (OTG) connectivity •2 DAC •2 TWI •Power jack •SPI header •JTAG header •Reset & erase button •Dimensions:101.52 mm x 53.3 mm •Compatible with Arduino Shields that use 3.3 V power supply and are compliant with the 1.0 Arduino pinout
