首先感谢灵眸科技 & 电子发烧友给与的试用机会。
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。
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:
wifi_start.sh AP_NAME PASSWORD
成功后如下显示:

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。
