Arduino DUE (Updated)Arduino DUE (Aggiornato)

Arduino DUE - Summary

Microcontroller	AT91SAM3X8E
Operating Voltage	3.3V
Input Voltage (recommended)	7-12V
Input Voltage (limits)	6-20V
Digital I/O Pins	54 (of which 12 provide PWM output)
Analog Input Pins	12
Analog Outputs Pins	2 (DAC)
Total DC Output Current on all I/O lines	130 mA
DC Current for 3.3V Pin	800 mA
DC Current for 5V Pin	800 mA
Flash Memory	512 KB all available for the user applications
SRAM	96 KB (two banks: 64KB and 32KB)
Clock Speed	84 MHz

WARNING: The current diagram of microDRUM is not compatible with the Arduino DUE. Even the code is not compatible because of the different processor. I made the changes on a micro-microDRUM and seems to work. I will try to see if it can use the DAC to generate usable sounds, only if I can make it work I will share changes to the schema and code.

The last stepThe last step

We arrived, after nearly two years of development, the last barrier was broken. The microDrum firmware becomes Open Source. I think it's an important step because the quality of microDrum no longer depend only on me but also by those who want to devote his time. So it is important that each of you publicize this project in order to bring together a larger number of developers. For version 1.1beta ...
