ODROID-C2 ARM SBC Offers Great Performance For $40

Hardkernel's ODROID-C2 64-bit ARM single board computer retails for $40 USD and is powered by an Amlogic S905 SoC. While just a fraction more than a Raspberry Pi 3 or the Pine 64+ when factoring in shipping costs, there's very competitive performance out of this board with its four cores running up to 2.0GHz.
