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 operations. It can be used for energy-saving sensor networks and demanding tasks such as language 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 area is between 80 MHz and 240 MHz. The user can switch off the performance of the CPU and use the power-saving co-processor to continuously monitor the peripheral devices.

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

The module integrates conventional 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 enables the connection to mobile phones or the transmission of BLE beacons to facilitate signal detection.

Land of the ESP32 chip - the current is less than 5 µA and is therefore suitable for battery -operated portable electronic devices. The data transfer rate supported by the module is up to 150 Mbps.

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

Excellent performance in terms of transmission distance, power consumption and network connectivity. The ESP32 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.

A operation with 5V voltage damages the module!
