首先，感謝RT-Thread給ART-Pi Smart 開發板初次嘗鮮機會

本文ART-Pi Smart開箱及初次體驗內置應用
?
開箱

收到有幾天了。我們一步一步揭開他的面紗吧

主板包裝精美嚴實，但需要保護的屏反而包裝簡單了

開箱后，包裝內全家福，包裝內自帶了兩根 Type-C 線和一根網線。開發板整體接口還是很豐富的：SDIO、USB、ETH、LCD、Camera。

本想用udbpush到板子上，幾次嘗試，都失敗，還是用古法，下載到SD卡，斷電插卡，再重新上電

切換目錄到sd卡

msh />cd sd

查看文件

msh /sd>lsDirectory /sd:AlmVoice            

查看sdl用法

總結

ART-Pi Smart啟動速度快，用戶程序與內核分離，可以獨立開應用，很棒的設計．但有點美中不足，網絡連接速度太慢了．
