ESP8266

The ESP8266 is a low-cost Wi-Fi microcontroller developed by Espressif Systems, widely used in Internet of Things (IoT) applications. It features a 32-bit Tensilica L106 microprocessor operating at 80 or 160 MHz, integrated with a full TCP/IP stack. The chip supports various interfaces, including GPIO, SPI, I²C, and UART, making it versatile for numerous projects. Its compact design and energy efficiency make it suitable for battery-powered devices and wearable electronics.

ESP8266 Main Features

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.

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.

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.

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.
