The generic microcontroller unit (MCU) on Intel® Edison Boards provide real-time peripheral control capabilities for GPIOs, UARTs, and I2C interfaces. The table below shows how fast digital pins (GPIOs) on an Intel® Edison Kit for Arduino* toggle on and off.
| Note | The toggling of the digital pins didn't use delays or sleeps of any sort. Digital pins were toggled on and off individually by the MCU. | |
| Arduino* Pin | Width [µs] | Frequency [kHz] | Period [µs] | | DIG0 | 18.7 | 26.71 | 37.44 | | DIG1 | 18.82 | 26.55 | 37.66 | | DIG2 | 18.48 | 27.03 | 37 | | DIG3 | 5.7 | 87.57 | 11.42 | | DIG4 | 18.58 | 26.88 | 37.2 | | DIG5 | 5.83 | 85.76 | 11.66 | | DIG6 | 24.66 | 19.99 | 50.02 | | DIG7 | 9.67 | 51.63 | 19.37 | | DIG8 | 9.79 | 51.05 | 19.59 | | DIG9 | 25.13 | 19.91 | 50.22 | | DIG10 | 8.91 | 56.09 | 17.83 | | DIG11 | 9.11 | 54.79 | 18.25 | | DIG12 | 9.01 | 55.46 | 18.03 | | DIG13 | 8.78 | 56.82 | 17.6 | |
