Android Things feature 2 hardware introduction

After 2016 years of Brillo's first developer feedback, as well as market research, the Android things operating system was formed to accommodate the habits of the vast majority of Android developers. Fully compatible with Android Studio's development environment.
February 8 This year, Google announced the developer Preview 2 (DP2) version.

A version number will be updated approximately every 6-8 weeks later. The DP2 version number has been made for example the following improvements:
The Development Board incorporates USB audio support and is integrated into the system's Hardware abstraction layer (HAL).

Overcomes some of the hardware-related issues on the Raspberry Pi 3.
Added support for the Intel Joule Development Board.

Android Things now supports 4 development boards: Android Things now supports 4 development boards: The Intel Edison Board, the Intel Joule Development Board. NXP Pico I.mx6ul Development Board and Raspberry Pi 3 Development Board.

The four boards take into account both the arm and the X86 architecture, as well as the 32-bit and 64-bit systems. All development boards Support WiFi and Bluetooth.
We're going to meet the true colors of these four development boards.

The x86 series has two boards supporting Android things. Inte Edison and Intel Joule,joule were the only chips shipped in 2016. Is the latest embedded CPU.

Intel Joule brings some new features compared to the Intel Edison Development Board. In addition to the frequency and memory performance improvements, there are also high-definition video processing interfaces. HDMI is used for high-definition display output, it is worth mentioning that the HDMI itself is to support the transmission of audio signals. Maybe it can be expanded oh.

Now with the USB audio to overcome the problem of sound. And CSI-2 is the 2nd edition of the CSI Agreement of the Mipi Alliance, which is also a more advanced technology. WiFi this piece. The 802.11AC is dual-mode and can be used in both 2.4G and 5G two bands. The Bluetooth protocol also has an upgrade. and USB support, is a big bright spot. USB3.0 OTG also backed up.

Two development boards under the comprehensive x86 structure. We'll see. Android Things has a full range of support for WiFi, video and audio. It also means that Android things can solve problems with audio, video, and other data input.

Let's take a look at arm's two development Board comparison

ARM's Development Board, also has audio and video support, and all have wired network port support. Now we need all kinds of transmission data channel, Android things can be a mouthful.

Because the android things kernel is also based on the Linux kernel, it supports MMU and multi-tasking.

We know that in the architecture of arm. The CPU of the CORTEX-M series does not support MMU, and is generally used as a node or endpoint device. Android Things is capable of supporting cortex-a CPUs. Can be used for most nodes. Or a routed, gateway-related node.

The biggest difference between Android things and Android is that Android things is a universal system tailored for the internet of things. The main support for sensors, peripherals related program development. But it's easier than traditional embedded development. Basically encapsulates hardware-related interfaces, and using software developers to invoke hardware is easier.

Even if you just know a little bit about hardware. It is also possible to complete the development of IoT applications, Android developers. Faster adaptation to Android things application development.
From the BSP level, Google manages the BSP-related code and does OTA support to ensure the reliability and security of the code.
