 The Espressif Systems ESP8266 is used in cheap WiFi modules. It embeds an Xtensa LX3 CPU. ESP8266 boards named ESP-XX come with at least 1/2 megabyte of SPI flash for program storage.
+Also see [[tools:tasmota|tasmota]] for various applications of this processor.

 Although the ESP-01 only has 2 GPIOs, NodeMcu has I2C support and a circuit such as [[:projects:esp|this]] can extend its capabilities.
-=== Tasmota ===
-Tasmota is firmware providing support for various devices attached to an ESP8266. It has both and HTTP (web) and MQTT interface.
-It was primarily designed for SONOFF power switches but can be used with any device to give an MQTT enabled WIFI temperature monitor, for example.
-Here is an example seession for a SONOFF basic switch.
-Backup factory firmware.
