# Developer Kit

Developer Kit 是 AliOS Things 官方出品的高阶开发板，提供了比 [Starter Kit](https://github.com/librae8226/doc/tree/a18f68206bdb5f166b24658a7ca7ee8f48b12d18/zh-ch/starterkit.md) 更加丰富的资源。

在传感器方面，除了惯导类加速度计、陀螺仪以外，还提供了大量环境感知类器件如磁力计、气压计、温湿度传感器、红外传感器以及接近光传感器，可以为各类物联网业务场景提供云端一体化集成的方案验证。

在硬件接口能力方面该款开发板资源也首屈一指，USB OTG, SD Card, Mini PCIe, Arduino shield 接口等等均有支持。另外板上集成 MCU 外挂 WiFi 模组方案，通过 SAL(Socket Adapt Layer) 为应用开发和数据上云提供了极简途径。

和 Starter Kit 一样，用户可以直接使用板载 ST-LINK V2 进行固件烧录和调试。

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://aliosthings.gitbook.io/docs/documentation/hardware/boards/developerkit.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
