Powered by Espressif’s advanced SoC, ESP32-WROOM-32 features high performance, a wide range of peripherals, Wi-Fi and bluetooth radio, which provide a complete solution tailored to advanced IoT applications.

Compact Design : the ESP-WROOM-32, measuring 25.2mm X 18mm only, contains the ESP32 SoC, flash memory, precision discrete components, and PCB antenna to provide outstanding RF performance in space-constrained applications.

Optimised layout : The ESP-WROOM-32 pinout is optimized, since peripheral IO pads are grouped and led out to facilitate application board design with minimal external trace routing, thus making the application even more compact.

Open and Free : We’re going open-source yet again! The ESP-WROOM-32 schematics and PCB layout are freely available for download and may be used as a design reference for developing fully-customized ESP-32 based hardware designs.

Application Ready : Suitable for commercial application development with a robust 4 layer FCC, CE (RED), IC, TELEC, SRRC & KCC-compliant design and a wide operating temperature range of -40°C to 85°C.



Espressif Systems Dual-Core Wi-Fi® Dual-Mode Bluetooth® Modules

Espressif Systems Dual-Core Wi-Fi® Dual-Mode Bluetooth®/BLE (Bluetooth Low Energy) Modules are compact, high-performance, low-power devices designed to provide a complete wireless solution tailored to advanced IoT applications. These Modules are powered by the Espressif Systems ESP32 System-on-Chip (SoC), and feature a wide range of peripherals, software stacks, flash memory, and an integrated antenna.

These Modules feature two independently-controlled CPU cores with adjustable clock frequency, offering a range from 80MHz to 240MHz.

The Modules are fully pre-certified, allowing faster time to market with reduced development costs. These Modules can also be easily integrated into space-constrained devices, due to their small size.
