Description

The ESP-WROOM-32 module is a universal WiFi-BT-BLE MCU module with powerful functions and a wide range of uses. It can be used for low-power sensor networks and demanding tasks, such as voice coding, audio streaming, and MP3 Decoding etc. The core of this module is the ESP32 chip, which is scalable and adaptive. The two CPU cores can be individually controlled or powered on. The adjustment range of the clock frequency is from 80 MHz to 240 MHz. The user can cut off the power of the CPU and use the low-power coprocessor to continuously monitor the status changes of the peripherals or whether certain analog quantities exceed the threshold. The ESP-WROOM-32 module also integrates a wealth of peripherals, including capacitive touch sensors, Hall sensors, low-noise sensor amplifiers, SD card interface, Ethernet interface, high-speed SDIO/SPI, UART, I2S and I2C, etc. . ESP-WROOM-32 module hereinafter referred to as ESP32.  

ESP-32 integrates traditional Bluetooth, low energy 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 to mobile phones or broadcast BLE Beacon facilitates signal detection. The sleep current of the ESP32 chip is less than 5uA, making it suitable for battery-powered wearable electronic devices. ESP-32 supports a data transmission rate of up to 150 Mbps. After passing through a power amplifier, the output power can reach 22 dBm, enabling ZUI's wide-range wireless communication. Therefore, this chip has industry-leading technical specifications and has excellent performance in terms of high integration, wireless transmission distance, power consumption, and network connectivity. The operating system of ESP32 is freeRTOS with LWIP, and TLS 1.2 with hardware acceleration is built-in. The chip also supports OTA encryption upgrades, and developers can continue to upgrade after the product is released.
