===ESP 8266 General Information=== | ====== ESP 8xxx Family ====== |
The ESP8266 is a low-cost system-on-chip (SoC) microcontroller with WiFi and full TCP/IP stack capability ((https://en.wikipedia.org/wiki/ESP8266)). The main advantages of that family are: | {{:en:iot-open:czapka_b.png?50| General audience classification icon }}{{:en:iot-open:czapka_e.png?50| General audience classification icon }}\\ |
* Low power consumption, | At the moment, the ESP 8xxx family includes the following chips: |
* Availability of WiFi and Bluetooth connections, | |
* Wide availability of low-cost modules from various suppliers, | |
* Wide availability in a variety of form factors, including SoC. | |
| |
The low price and the fact that there were very few external components on the module, which suggested that it could eventually be very inexpensive in volume, attracted many users to explore it. | |
The ESP8285 module continues the ESP8266 line with 1 MB of built-in flash, higher integration, and reduced dimensions. | |
For now, the ESP8266 family includes the following chips: | |
* ESP8266EX (figure {{ref>esp8266EX_chip}}), | * ESP8266EX (figure {{ref>esp8266EX_chip}}), |
* ESP8285 (figure {{ref>esp8285_chip}}). | * ESP8285 (figure {{ref>esp8285_chip}}).\\ |
