Sipeed MAIX Dock K210开箱试用
凑下字数
这两年人工智能是发展的热火朝天，咱也不能落伍，无意之间发现了勘智 K210这款芯片，价格便宜但是性能不俗，主频400MHz，还能再超频，双核，自带KPU，甚是强大，截两张官方datasheet关于这个芯片的简介，大家来感受下
不知道大家有没有被震撼到，这玩意真能这么牛
废话不多说，拍两张开发板照片给大佬们过下目
图片背景是某米的鼠标垫，这个广告打的，某总是不是要打点钱过来
这个是被我改造过的，把屏幕黏在了开发板的模块上，不得不说买开发板送的那个小盒子我还是挺喜欢的
简介也有了，照片也看过了，接下来再不来点干货怕是过不去了
好了接下来我们按照官方的教程先跑一个人脸识别，贴下源码
关于源码和教程在官方的网站和gothub都可以找到，等会我会贴出来

总结
K210的可玩性还是挺高的，随着AI的发展这种低功耗低成本的方案需求肯定会越来越多，美中不足的是K210这个芯片的内存有点小，刨去AI部分用掉的留给用户的并不多，希望能再不就的将来K210能够衍生出更多的系列来供大家使用
