## Description

## Overview

Released in 2016, the ODROID C2 was a landmark SBC as one of the first 64-bit ARM boards available at a competitive price. It is powered by the Amlogic S905 quad-core Cortex-A53 SoC clocked at 1.5 GHz, paired with 2GB of DDR3 RAM — generous for its era. A Mali-450 GPU handles graphics and basic media decode duties.

The C2 includes a microSD slot and an eMMC module connector, four USB 2.0 ports, HDMI output, and Gigabit Ethernet. A 40-pin GPIO header provides I2C, SPI, and UART access for embedded projects. Note that Amlogic S905 devices can be sensitive to SD card brand compatibility, and some USB-related quirks have documented workarounds in the community wiki.

Armbian continues to provide images for the C2 with both minimal/IoT and desktop variants. While newer Hardkernel boards have superseded it in raw performance, the C2 remains a solid choice for lightweight server tasks, home automation, and as an introduction to 64-bit ARM Linux. Power is supplied via a 5V/2A DC barrel jack.
