【EASY EAI Nano开源套件试用体验】一次美丽的邂逅：EASY EAI Nano开箱+初步试用-remotely开源

首先感谢灵眸科技 & 电子发烧友给与的试用机会。 一、开箱&硬件规格

EASY EAI Nano开源套件基于RockChip RV1126 SoC，其规格简单描述如下：

四核ARM Cortex-A7 + RISC-V MCU的规格目前还是够用，要是改成A53最好了，2.0Tops的NPU性能相当不错，RKNN的支撑让各种人工智能应用迅速落地部署。

EASY EAI Nano的板子很漂亮，军绿色的PCB，稍微比树莓派大点，具体如下图。

板载1G DDR3内存和8G emmc存储，另外支持TF卡扩容。套件拿到后，为了便于试用，直接组装起来了，这样方便。

二、上电

套件提供了ADB（J7）接口，这点非常的赞！

进入ADB SHELL后，先联网，使用wifi_start.sh脚本，按照如下格式：

成功后如下显示：

三、一个demo

板载EMMC的分配和使用情况，其中userdata目录用于用户的一些应用和模型存储。

板载一个人脸门禁的DEMO，直接运行起来：

应用启动迅速，程序跑起来界面很流畅，还带人脸识别功能，运行这个程序的时候RV1126芯片有点热。
