| <p>You can create builds for Nexus devices using Android Open Source Project |
| (AOSP) builds and the relevant hardware-specific binaries. For available |
| Android builds and targeted devices, see |
| <a href="../start/build-numbers.html#source-code-tags-and-builds">Source Code |
| Tags and Builds</a>.</p> |
| |
| <p>You can also create builds for |
| <a href="https://android.googlesource.com/device/linaro/hikey/" class="external">HiKey</a> |
| Android reference boards, which are designed to help non-Nexus component vendors |
| develop and port drivers to Android releases. Using a reference board can ease |
| upgrade efforts, reduce time-to-market for new Android devices, lower device |
| costs by enabling ODM/OEMs to choose from a wider range of compatible |
| components, and increase the speed of innovation among component suppliers.</p> |
| |
| <p>Google supports <a href="#960hikey">HiKey960</a> and |
| <a href="#620hikey">HiKey</a> certified |
| <a href="https://www.96boards.org/products/ce/" class="external">96Boards</a> |
| as Android reference boards. AOSP provides kernel source and board support for |
| HiKey so developers can easily create and debug new and existing peripheral |
| drivers, do kernel development, and perform other tasks with fewer OEM |
| encumbrances. To develop new ContextHub features that use new sensors or LEDs, |
| you can also use a <a href="#neonkey">Neonkey SensorHub</a> connected to a HiKey |
| or HiKey960 development board.</p> |
| |

| <p>The HiKey960 board is available in a 3GB RAM configuration from LeMaker (via |
| <a href="https://www.amazon.com/dp/B071RD3V34" class="external">Amazon.com</a>) |
