你好，请问如果我们有一款RTL8722DM的模块（非开发板，是我们自己开发的模组），如何才能支持Arduino？  
是否只能使用官方的开发板才能支持Arduino？

理论上，模块也是能支持 Arduino，但是需要分开供电，和需要另外链接 USB 转 UART 芯片来上传程序。

开发板主要功能也就是供电线路，USB 转 UART 线路链接到 LOG\_UART，RESET 和 UART\_DOWNLOAD 按键。  
其他功能就可有可无了，看开发板的设计目的，如 LED，SD 卡槽，更多的按键，麦克风，3.5mm TRS接口。

你指的是哪个 SDK 链接？

Arduino: [GitHub - ambiot/ambd\_arduino: AmebaD Arduino third-party package SDK](https://github.com/ambiot/ambd_arduino)  
Standard SDK: [GitHub - ambiot/ambd\_sdk: SDK for AmebaD](https://github.com/ambiot/ambd_sdk)

是的，请问我应该用你列出来的哪个SDK？

Arduino: 安装，设置和用起来比较简单，能用 Arduino IDE，不是所有芯片功能都支持  
Standard SDK: 设置和用起来比较复杂，编译是直接用 GCC 或者 IAR，所有芯片功能都支持，有示例

所以，我用自己的模块，我也有自己的evb开发板，我参考  
Arduino: [GitHub - ambiot/ambd\_arduino: AmebaD Arduino third-party package SDK](https://github.com/ambiot/ambd_arduino)  
应该就可以把aiduino跑起来，对吧？

对，只要你有个 USB-UART 上传方法，Arduino 编译出来的程序应该能跑。但是因为 Arduino 没有具体针对你的开发板的支持，Arduino 里面的引脚号码不一定会和开发板上对应
