Espressif Systems

Espressif Systems is dedicated to the research, design, and development of Wi-Fi and Bluetooth solutions. Espressif Systems’ SoCs are used in mobile devices, home appliances and industrial applications. Their Wi-Fi chipsets integrate TR filters, diplexers, power amplifiers, receive low noise amplifiers, RF baluns and antenna switch – all in a single piece of silicon, with less than 8 external components to realise Wi-Fi functionality.


Espressif® Smart Connectivity Platform is a family of highly integrated, low power, high performance Wi-Fi chipsets and modules that connect embedded devices to the Internet.

The flagship ESP32 combo Wi-Fi / Bluetooth device integrates 32-bit processor, 802.11BGN Wi-Fi transceiver, in-built antenna switches, RF balun, power amplifier, low noise receive amplifier, filters, and power management modules. ESP32 adds complete Wi-Fi functionality and versatility to your applications with minimal PCB area requirements.

ESP32 can perform as a complete, standalone system or as a slave device to a host MCU to reduce communication stack overhead on the main application processor. ESP32 can interface with other systems to provide Wi-Fi and Bluetooth functionality through the SPI / SDIO or I2C / UART interfaces..

Engineered for mobile devices, wearable electronics and the Internet of Things (IoT) applications, ESP32 achieves ultra low power consumption with a combination of several proprietary technologies. The state-of-the-art power saving features include fine resolution clock gating, power modes, and dynamic power scaling.
