ESP32 Wi-Fi & Bluetooth Modules I Espressif

ESP32 Series of Modules

Powerful Wi-Fi+Bluetooth/Bluetooth LE modules
that target a wide variety of AIoT applications,
ranging from low-power sensor networks to the
most demanding tasks.

Title

Features

Wi-Fi & Bluetooth Dual Mode

The integration of Wi-Fi, Bluetooth and Bluetooth LE ensures that a wide range of applications can be targeted, and that our modules are truly versatile. Using Wi-Fi ensures connectivity within a large radius, while using Bluetooth allows the user to easily detect a module (with low-energy beacons), and connect it to a smartphone.

High Integration

With in-built antenna switches, RF balun, power amplifier, low-noise receive amplifier, filters, and power management modules, our chips add priceless functionality and versatility to your applications with minimal PCB requirements.

Configurability and Customization

ESP32 modules can be ordered with different antenna configurations (e.g. PCB antenna, antenna connector) and flash sizes, so that they correspond to the needs of different applications. ESP32 modules also offer manufacturing customizations with pre-programmed application firmware, custom data and pre-provisioned cloud certificates.

Application-Ready

All ESP32 Series of modules have a wide operating temperature range of -40°C to 105°C, and are suitable for commercial application development with a robust 4-layer design that is fully compliant with FCC, CE-RED, SRRC, IC, KCC & TELEC standards.

Comparison of Parameters

ESP32-WROOM Series

These are ESP32-D0WD-based modules with integrated flash. These modules are well suited for Wi-Fi and Bluetooth/Bluetooth LE-based connectivity applications and provide a solid dual-core performance.

ESP32-WROVER Series

The ESP32-WROVER series is based on ESP32-D0WD SoC, having also integrated flash memory and SPIRAM. It achieves a fine dual-core performance, and is well suited for applications requiring more memory, such as AIoT and gateway applications.

ESP32-MINI Series

The ESP32-MINI series is based on ESP32-U4WDH and has integrated flash memory, thus providing a cost-effective solution for simple Wi-Fi and Bluetooth/Bluetooth LE-based connectivity applications.
