The
ESP8266 was popularized in the English-speaking maker community
in August 2014 via the ESP-01 module, made by a third-party manufacturer
Ai-Thinker. This small module allows microcontrollers to connect to a Wi-Fi
network and make simple TCP/IP connections using Hayes-style commands. However,
at first, there was almost no English-language documentation on the chip and
the commands it accepted. The very 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 hackers to explore the module,
the chip, and the software on it, as well as to translate the Chinese
documentation. The ESP8285 is a similar chip with a built-in 1 MiB flash
memory, allowing the design of single-chip devices capable of connecting via
Wi-Fi. These microcontroller chips have been succeeded by the ESP32 family of
devices.

1.High
Durability

ESP8266EX
is capable of functioning consistently in industrial environments, due to its
wide operating temperature range. With highly-integrated on-chip features and
minimal external discrete component count, the chip offers reliability,
compactness and robustness.

2.Compactness

ESP8266EX
is integrated with a 32-bit Tensilica processor, standard digital peripheral
interfaces, antenna switches, RF balun, power amplifier, low noise receive
amplifier, filters and power management modules. All of them are included in
one small package, our ESP8266EX.

3.Power-Saving
Architecture

Engineered
for mobile devices, wearable electronics and 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. This allows battery-powered
designs to run longer.

4. 32-bit
Tensilica Processor

The
ESP8266EX microcontroller integrates a Tensilica L106 32-bit RISC processor,
which achieves extra-low power consumption and reaches a maximum clock speed of
160 MHz. The Real-Time Operating System (RTOS) and Wi-Fi stack allow about 80%
of the processing power to be available for user application programming and
development.
