Widora AIRV/K210 Board with ESP8266/ESP8285 Espressif Wifi and Kendryte K210 AI

Having been keeping an eye on Widora and Espressif for quite a bit. I finally decided to test out Widora's development board AIRV.

1. Background Knowledge

1.1 Espressif

Espressif is based in Shanghai, China, focusing on Wifi/Bluetooth chips, now have two main Wifi modules: * ESP32: Wifi with Bluetooth * ESP8266/ESP8285: Wifi ONLY

1.2 Widora

Widora is headquartered in Beijing, China, providing development boards using Espressif Wifi/Bluetooth chips.

1.3 Kendryte

NEVER heard of Kendryte before. It seems Kendryte develops some AI based on Risc-V chip architecture? That seems to be a good concept...

1.4 HiFive

As for Risc-V, HiFive developed by SiFive has to be mentioned in any case.

For me, a NOBODY has NOT had any chance or capability to deal with chips... So... shame... Anyway, let's test it out... ^_^

2. Test on Widora AIRV Face Detection

By using a RUBBISH USB cable, you should already be able to run the face detection sample code existing inside the board.

However, you really need to use a QUALIFIED Micro-B USB to USB Type A cable, in order to list the device out by lsusb.
