The ESP8266EX is integrated with a 32-bit Tensilica processor, standard peripheral digital interfaces, antenna switches, power amplifier, low noise amplifier, filters and power management modules. All of this is included in a small package, ESP8266EX
Low power architecture
Designed for mobile devices, portable electronics and IoT applications, ESP8266EX performs low power consumption combining several patented technologies. The energy saving architecture features three modes of operation: active mode, sleep mode, and deep sleep mode. This allows battery-powered models to work longer.
The ESP8266EX is capable of consistently operating in industrial environments due to its wide range of operating temperatures. With integrated chip features and minimal external discrete components, the chip delivers reliability, compactness and robustness.
Quick integration solutions
ESP-WROOM-02 is a 32-bit MCU Wi-Fi MCU based on ESP8266 chip. The TCP / IP network, 10-bit ADC and HSPI/UART/PWM/I2C /I2S interfaces are all embedded in this module.
The ESP-WROOM-S2 uses a 2 MB SPI flash connected to HSPI, running as a slave SDIO / SPI, with SPI up to 8 Mbps.
The ESP8266 can work in a low-power connectivity mode. For example, if it works in DTIM10, it consumes only 1.2mW, maintaining a Wi-Fi connection. The module also integrates a 16 Mbits SPI flash used for storing user programs, data, and firmware.
