44 * The LinkSprite pcDuino2 board is almost identical to the older
45 * LinkSprite pcDuino1 board. The only software visible difference
46 * is that the pcDuino2 board got a USB VBUS voltage regulator, which
47 * is controlled by the PD2 pin (pulled-up by default). Also one of
48 * the USB host ports has been replaced with a USB WIFI chip.
