Product Description

ESP32-DOWD chip has the characteristics of scalable and adaptive. Two CPU kernels can be controlled separately. The adjustment range of the clock frequency is 80 mHz to 240mH2. Users can cut off the power supply of the CPU and use the low -power association processor to continuously monitor the state changes in the peripherals or whether certain simulation quantities exceed the inter -value. ESP32 also integrates rich peripherals, including capacitive touch sensors, Hall sensors, SD card interfaces, Ethernet interfaces, high -speed SDIO/SPI, UART, 2S and 2C, etc.

The module integrates traditional Bluetooth, low power consumption Bluetooth and Wi-F, which has a wide range of uses: Wi-Fi supports a large-scale communication connection, and also supports directly connecting the Internet through routers; Bluetooth allows users to connect to mobile phones or broadcast BLE Beacon is easy to detect signal detection. The sleep current of the ESP32 chip is less than 5 A, which makes it suitable for wearable electronic equipment for battery power supply. The data transmission rate supported by the module is as high as 150 Mbps and the antenna output power reaches 20 dBM, which can achieve the maximum range of wireless communication. Therefore, this module has industry -leading technical specifications, which has excellent performance in high integration, wireless transmission distance, power consumption, and network Unicom.

The operating system of the ESP32 is a RERTOS with LWP. It also has a built -in TLS 1.2 with a hardware acceleration function. The chip supports OTA encryption upgrade at the same time, so that users can continue to upgrade after product release.
