HiKey (LeMaker version) is powered by the Kirin 620 SoC with eight-core ARM Cortex-A53 64-bit CPU up to 1.2GHz and high performance Mali 450MP4 GPU. It also has 1GB/2GB LPDDR3 DRAM (800MHz) and 8GB eMMC storage on board.
HiKey is also a board that satisfies the Linaro LCG 96boards design specification. About 96boards, we can see more from https://www.96boards.org. With the standardized expansion buses for peripheral I/O, display and cameras in the 96boards ecosystem, we have many add-ons to work on HiKey. LeMaker, as one of the LCG members, Lemaker will contribute more resource and technical support to 96boards community.
