ESP32-WROOM-32 Module

ESP32-WROOM-32 Wi-Fi and Bluetooth Module

The ESP32-WROOM-32 is a compact Espressif MCU module for connected embedded designs. It combines an ESP32-D0WDQ6 dual-core Xtensa LX6 processor (up to 240 MHz), 4 MB SPI flash, a PCB antenna, 2.4 GHz Wi-Fi, Bluetooth 4.2 BR/EDR and Bluetooth Low Energy.

Key features

• 2.4 GHz Wi-Fi 802.11 b/g/n and Bluetooth 4.2 Classic and LE
• 4 MB external SPI flash; dual-core 32-bit Xtensa LX6 CPU up to 240 MHz
• Module supply: 3.0–3.6 V DC; use a suitable regulated power supply
• UART, SPI, I2C, I2S, ADC, DAC, PWM and touch-capable interfaces, subject to pin allocation
• On-board PCB antenna

Applications

Suitable for wireless sensors, home automation, robotics and custom IoT boards. This is a module for integration into a host PCB, not a USB development board.
