ESP-32 ESP-WROOM-32 Adapter WiFi Module Arduino IoT Serial Board Tasmota 15

Product Description:

ESP-32 ESP-WROOM-32 Wireless Transceiver Module

Already flashed with the latest Tasmota firmware.

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

At 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 disable the CPU and use the low-power coprocessor for continuous monitoring of peripherals. The ESP32 also integrates a wealth of peripherals, including capacitive touch sensors, Hall sensors, a low-noise sensor amplifier, an SD card interface, an Ethernet interface, high-speed SDIO/SPI, UART, I2S, and I2C, etc. The module integrates conventional Bluetooth, low-power Bluetooth, and Wi-Fi, offering a wide range of applications: Wi-Fi supports a broad spectrum of communication connections. The router connects directly to the internet, while Bluetooth enables connection to mobile phones or the transmission of BLE beacons for easier signal detection. The ESP32 chip's sleep mode draws less than 5 µA, making it suitable for battery-powered portable electronic devices. The module supports a data transfer rate of up to 150 Mbps.

Antenna performance - The power reaches 20 dBm, enabling the greatest range for wireless communication. Therefore, this module boasts 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.

CAUTION: The module and I/Os must be operated with 3.3V.

Operation with 5V will damage the module!
