The ESP8266 integrates a 160 MHz microcontroller with a full Wi-Fi front-end (both as client and access point) and TCP/IP stack with DNS. ESP8266’s flexibility and price point have driven its explosion of use. It is produced by Shanghai-based Chinese manufacturer, Espressif. The chip became popular for IoT with the ESP-01 module, made by a third-party manufacturer, AI-Thinker.
ESP8266EX is among the most integrated Wi-Fi chips in the industry. Measuring just 5mm x 5mm, ESP8266EX requires minimal external circuitry and integrates a 32-bit Tensilica MCU, standard digital peripheral interfaces, antenna switches, RF balun, power amplifier, low noise receive amplifier, filters and power management modules – all in one small package.
Engineered for mobile devices, wearable electronics and the Internet of Things (IoT) applications, ESP8266EX achieves low power consumption with a combination of several proprietary technologies. The power saving architecture features three modes of operation – active mode, sleep mode and deep sleep mode, thus allowing battery-powered designs to run longer.
