ESP32 SoC

High Level of Integration

ESP32 is highly-integrated with in-built antenna switches, RF balun, power amplifier, low-noise receive amplifier, filters, and power management modules. ESP32 adds priceless functionality and versatility to your applications with minimal Printed Circuit Board (PCB) area requirements.

Hybrid Wi-Fi & Bluetooth

ESP32 can perform as a complete standalone system or as a slave device to a host MCU, reducing 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.

Ultra-Low Power Management

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

Robust Design

ESP32 is capable of functioning reliably in industrial environments with an operating temperature ranging from -40°C to +125°C. Powered by advanced calibration circuitries, ESP32 can dynamically remove external circuit imperfections or adapt to changes in external conditions.
