ESP32 WROOM-32 38-pins Wifi+Bluetooth MCU Module

The ESP32 WROOM-32 is a versatile WiFi-Bluetooth-BLE MCU module designed for a wide range of applications, from low-power IoT sensor networks to advanced projects like voice encoding, music streaming, MP3 decoding, and smart home automation. Powered by dual CPU cores with adjustable clock speeds from 80 MHz to 240 MHz, it delivers scalable and high-performance computing for hobbyists, developers, and electronics enthusiasts.

Ideal for wearable electronics, IoT devices, and battery-powered projects, the ESP32 WROOM-32 consumes less than 5mA in low-power mode. Users can power off main CPUs while the low-power coprocessor efficiently monitors peripherals and thresholds. With integrated peripherals including capacitive touch sensors, Hall sensors, SD card interface, Ethernet, high-speed SDIO/SPI, UART, I²C, and on-board PCB antenna, the module provides seamless connectivity. Wi-Fi enables fast internet access up to 150 Mbps, and Bluetooth/BLE supports phone pairing and low-energy beacon broadcasting.
