ESP32 WROOM Series

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

ESP32 WROOM Series

Compact Design

Modules in the ESP32 WROOM Series contain the ESP32 SoC, flash memory, precision discrete components and a PCB/IPEX antenna which achieves outstanding RF performance in space-constrained applications.


Optimized Layout

Modules in the ESP32 WROOM Series have an optimized pinout, since peripheral IO pads are grouped and led out to facilitate application board designs with minimal external trace routing. This makes any resulting applications highly compact.

Open and Free

We’re totally open-source, as ever! The schematics and PCB layout of all modules in the ESP32 WROOM Series are freely available for download and may be used as a reference for developing fully-customized ESP32-based hardware designs.


All modules in the ESP32 WROOM Series are 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.


ESP32-WROOM-32SE integrates Microchip’s ATECC608A CryptoAuth chip in the module. This can be used for enhanced security to connect to IoT cloud services that use X.509 based mutual authentication and TLS based secure communication. This module remains pin compatible with the ESP32-WROOM modules family.
