The hottest module on the Internet of Things in the past few years is ESP8266, but now the hottest module is ESP32! It is easy to confuse that ESP32 is actually a control chip on the development board, not a development board! The Most Popular WiFi & Bluetooth Module in 2021 is ESP32-WROOM-32D.

ESP8266 is a low-cost and high-performance wireless SOC, which provides endless possibilities for integrating WiFi functions into other systems. It can control input and output like Arduino, but the special feature is that it comes with Wi-Fi. ESP series Wi-Fi modules are popular in IoT projects.

However, due to the fast update iteration speed and lack of module-related information, there are some confusions between ESP-12E Wifi Module and ESP-12F Wifi Module.

Micro:bit is a friendly electronic board developed by the BBC for teaching electronics, coding and other STEM topics. Mbits is a pocket-sized microcontroller, which not only has many of the same functions as Micro:bit V2, but it is also worth mentioning that Mbits is better than Micro:bit V2 in some functions! Let's see the excellence of Mbits, and use Mbits to DIY two smart devices for fun!
