![]() Without having to program the ESP, complex IoT applications could be developed, using the ESP simply as an external Wi-fi chip. Hobbyists all over the world started playing with the chip to see what it could do. While having Wi-fi on-chip with a microcontroller was not a new idea, the concept having a simple serial link to control it out of the box was. Fabless means they just create the chip design, and they get another company to actually manufacture the silicon (Atmel was also a fabless semiconductor company). The ESP8266 was designed by a Chinese fabless semiconductor company called Espressif. There's a lot of resources out there, but I wanted to combine all that information together into one place. The low cost of getting a module coupled with its power and reliability has made sales of the chip shoot through the roof. The ESP8266 has been popular for quite a while now.
