• ESP32-C3: welcome to the ESP32 family
    • Intro


      Espressif announced a new SoC some time in November of 2020. The chip is called ESP32-C3. I happen to get an engineering sample and I'm happy to share my thoughts on this.

      My post will be more towards DIY-community due to my own background. TLDR: I'm really excited about the new addition to ESP32 family and the new features it brings.

      ESP32-C3 vs others

      The ESP32-C3 is suppose to take a place somewhere between ESP32/ESP32-S and our old friend ESP8266.

      I won't be surprised if the goal is to replace ESP8266 and to take its place in ...

    • List of ESP8266-based modules

      There are several modules based on ESP8266 WiFi SoC. Each has its own field of use and functionality, although some look similar to others. The list mainly consists of ESP-xx variations of such modules which are widely available from online stores like eBay, Aliexpress, Tao, etc.


      I believe this is one of the first versions of ESP8266-based module produced in large quantities. This is probably how it started.

      It's simple and has limited number of GPIO pins, but it's still useful to get started. The 2.54mm-pitch 8-pin dual row header makes experimenting easier. Some ...

      I recently came across ESP8266 WiFi chip and various modules based on it. This is a low cost microcontroller with WiFi built into it. There is a huge community around ESP8266. You can develop for it using C, Lua and even Wiring using Arduino development tools.

      I decided to get my hands on it to play with it a little. I ordered some boards for a start. First, I needed some kind of easy prototyping dev board for easier testing. I got ESP-201 and Dev board designed specifically for it. After unsuccessful search looking for schematic ...
