The DigiX has a 32-bit 84 MHz MCU, embedded low power Wi-Fi (b/g/n), optional mesh networking, 99 usable i/o pins, audio output, USB on the go support, onboard EEPROM, onboard microSD slot, built in real time clock, and is 100% compatible with anything that works with the Arduino Due - no adapters, code changes, or special software needed! This is the ultimate Arduino compatible development board, ready for any project!
Here are the specifications:
The DigiX - like the Arduino Due, UDOO, and Spark Core runs at 3.3V. The maximum voltage that the I/O pins can tolerate is 3.3V. Connecting the I/O pins to higher voltages, including 5V, could damage the DigiX.
