The ESP32-C3-AWS-ExpressLink-DevKit is a development board that hosts Espressif’s AWS IoT ExpressLink module. It can be used with an external host MCU for easy evaluation and prototyping. The pin layout of ESP32-C3-AWS-ExpressLink-DevKit is compatible with that of the Arduino Zero development board and, therefore, it can be directly plugged into the Arduino Zero board, or be easily connected to other host MCUs, such as the Raspberry Pi".
    *Specs:
      *400 Kbyte RAM on the ESP32 chip.
      *4, 8, 16 MBytes of FlashMemory on the module.

    *Infos by Kin Cony, personally, 2021-10:
      *[[http://www.kincony.com/images/patent/ce.jpg|KinCony "GTS: Verification of Red Complicance"]] => A4, but not A8.
      *"We will later have CE certification for -A8, because we will design more channels new verison of A8. so we will make CE certification together.
      *"KC868-A4 has multi interface, A4 have IR sender and receiver, but A8 doesn't have. A8 has 4 GPIO for temperature sensor or LED strip, A4 has 1 port".
      *"IR receiver is for learning IR signal, then how to send IR signal, just according to your code, maybe by button, or by phone app, or by PC. It's up to you".
      *[[http://www.kincony.com/forum/forumdisplay.php?fid=6|KinCony "Smart Home Automation Forum › Technical Support > KC868-A series Smart Controller"]] - "All document and source code and video tour see here".
      *Boxing:
        *"Now A8 also has this boxed version, the box is the same as A4. Our website will be updated later. We can make a new link with box, already have box version in stock".
        *[[http://www.kincony.com/forum/showthread.php?tid=825|KinCony "Smart Home Automation Forum › Technical Support > KC868-A series Smart Controller" > " KC868-A4 and A8 plastic enclosure 3D printer stl file"]] - "We also shared some DIYer's 3D print file of A4,A8's BOX".
      *Training: We are making videos and in furture we will write books for A4,A8".
      *Product line & future new products: "my means update A8, we will make such as A32. that is 32 channel output, also is based on ESP32 chip. New board not instead of old board, just publish a new products. A4,A8,Ax all will based on ESP32. Board size according to channel number. A8 size = A4 size, ie. same size".
      *Software and application development by the users: 
        *"use ESP32 to make board, because so many software resource can be used, and easy integrate with ESPHome, ESPHome = Add-on plugin for home assistant.
        *[[http://youtu.be/FqybCoVQ59A|YouTube "Lesson21- KC868-A8 ESP32 ethernet work for home assistant by ESPhome"]].
        *"Everyone can write code for ESP32. You can use "arduino IDE" as programming tool, it's open source and free.
        *"Except A4,A8, all other controller not need users to write code. just directly to use".
        *"Because you can write ESP32 code, so you can do any logical functon. Now boards have DI,DO, AI,AO, you just make code for logical and function by yourself, such as input trigger output".
        *Software IDE: Arduino IDE or Visual Studio.
        *All programming languages "as long as the ESP32 compiler supports the language".
        *"Most our user use arduino. C also is ok".
