Hybrid Wi-Fi & Bluetooth Chip

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 its SPI / SDIO or I2C / UART interfaces.

 

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) requirements.

 

Ultra-Low Power Consumption
Engineered for mobile devices, wearable electronics and IoT applications, ESP32 achieves ultra-low power consumption with a combination of several types of proprietary software. ESP32 also includes state-of-the-art features, such as fine-grained clock gating, various 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 and adapt to changes in external conditions.

 

ESP32-WROOM-32
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.

 

Optimized 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 ESP32-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.
