The core of the ESP32-WROOM-32DC and ESP32-WROOM-32UC modules is the ESP32-D0WD chip, which belongs to the Espressif ESP32 series* and is scalable and adaptive. Both CPU cores can be controlled independently. The clock frequency can be adjusted from 80 MHz to 240 MHz. Users can cut power to the CPU and use a low-power co-processor to constantly monitor peripheral state changes or whether certain analog quantities exceed thresholds. ESP32 also integrates rich peripherals, including capacitive touch sensor, Hall sensor, 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 has a wide range of uses: Wi-Fi supports a wide range of communication connections, and also supports direct connection to the Internet through a router; Bluetooth allows users to connect mobile phones or broadcast BLE Beacon to facilitate signal detection. Espressif’s ESP32 chip has a sleep current of less than 5 µA, making it suitable for battery-powered wearable electronics. The module supports data transfer rates up to 150 Mbps and antenna output power up to 20 dBm for maximum range wireless communication. Therefore, this module has industry-leading technical specifications and excellent performance in terms of high integration, wireless transmission distance, power consumption, and network connectivity.

The operating system of Espressif ESP32 is freeRTOS with LwIP, and it also has built-in TLS 1.2 with hardware acceleration. The chip also supports OTA encryption upgrade, which is convenient for users to continue to upgrade after the product is released.
