ESP-32 ESP-WROOM-32 Wireless Transceiver Module

Already flashed with the latest Tasmota firmware.

ESP32-WROOM-32 is a universal Wi-Fi BT BLE MCU module with powerful functions and a wide range of applications. It can be used for low-power sensor networks and demanding tasks such as voice coding, audio streaming and MP3 decoding etc.

The heart of this module is the ESP32-D0WDQ6 chip*, which is scalable and adaptable. The two CPU cores can be controlled separately. The frequency Setting range is between 80 MHz and 240 MHz. The user can turn off the power of the CPU and use the low-power co-processor to continuously monitor peripherals.

ESP32 also integrates a wealth of peripherals, including capacitive touch sensors, Hall sensors, low noise sensor amplifier, SD card interface, Ethernet interface, high-speed SDIO/SPI, UART, I2S and I2C, etc.

The module integrates traditional Bluetooth, low-power Bluetooth and Wi-Fi and offers a wide range of possible uses: Wi-Fi supports a wide range of communication connections.

The router is directly connected to the Internet, while Bluetooth allows connection to mobile phones or the transmission of BLE beacons to facilitate signal detection.

ESP32 chip sleep mode - The current strength is less than 5µA, making it suitable for battery-powered portable electronic devices. The data transfer rate supported by the module is up to 150 Mbps.

Antenna performance - The performance reaches 20 dBm, which can achieve the longest range of wireless communication. Therefore, this module has industry-leading technical specifications.

Excellent performance in terms of transmission distance, power consumption and network connectivity. ESP32's operating system is freeRTOS with LwIP, and TLS 1.2 with hardware acceleration is integrated. The chip also supports OTA encryption.

ATTENTION: The module and the IOs must be operated with 3.3V.

Operation with 5V voltage damages the module!
