HOWCHIP 5420-DVK is a Mobile Development Kit with Samsung Exynos 5420 SoC, an OLED Display

With Arndale Octa already shipping, and the upcoming ODROID-XU2, we already have two low cost boards with Samsung Exynos 5420 big.LITTLE processor for less than $200. But if you want a more complete kit, HOWCHIP 5420-DVK with a 4.65″ OLED display and capacitive touchscreen, 2GB RAM, 4GB eMMC, and various connectors, could be an option. There’s also a Lite version without the OLED display.
