Most ODROID boards come equipped with three to five mixed USB 2.0 or 3.0 slots, HDMI output, and a 3.5 mm jack. Additionally, lower-level output is facilitated by general-purpose input/output (GPIO) pins supporting common protocols like I²C. The current models feature a Gigabit Ethernet (8P8C) port and an embedded MultiMediaCard (eMMC) module socket, enhancing connectivity and storage options.
