Arduino DUE 2012 R3 - 32-bit Main Control Development Board

Due is the first Arduino board with a built-in 32-bit ARM driver. The high clock speed of 84MHz combined with a total of 54 I/O pins enables very large projects to be implemented. At the same time, it maintains the simplicity of typical Arduino systems thanks to the extensive Arduino libraries and compatibility with most Arduino shields. The 54 pins include 12 PWM outputs and 12 analog inputs, as well as 4 UARTs, 2 TWI (I²C) chips and a dual DAC that is great for stereo sound. Additional possibilities are offered by its own USB host and support for standards such as JTAG, SPI and Micro-USB. 512 KB Flash and 96 KB SRAM keeps pace with the fastest processors.

Special features:

High clock frequency of 84MHz
54 I/O pins with 2 DACs
