ESP-WROOM-32 is a universal WiFi BT BLE MCU module, powerful and versatile
The module is the core ESP32 chip, with scalable, adaptive functions, two CPU cores can be controlled or powered on individually, the clock frequency can be adjusted from 80 MHz to 240 MHz, the user can cut off the power of the CPU, and use low-power co-processing The ESP32 also integrates a large number of peripheral devices, including capacitive touch sensors, Hall sensors, low-noise sense amplifiers, SD card interface, Ethernet interface, high-speed SDIO/SPI, UART, I2S and I2C
ESP-WROOM-32 integrates traditional Bluetooth, Bluetooth low energy and Wi-Fi, and has a wide range of uses: Wi-Fi supports a wide range of communication connections, as well as direct connection to the Internet through routers; Bluetooth allows users to connect mobile phones or broadcast BLE messages. Standard for signal detection, ESP32 chip sleep current is less than 5 A, suitable for battery-powered wearable electronic devices, ESP-WROOM-32 supports data rates up to 150 Mbps, and provides up to 22 dBm output power through a power amplifier for The largest range of wireless communication, therefore, the chip has industry-leading specifications and provides the highest performance in terms of high integration, wireless transmission distance, power consumption and network connectivity
The operating system of ESP32 is freeRTOS with LWIP, and built-in TLS 1.2 with hardware acceleration, the chip also supports OTA encryption upgrade, developers can continue to upgrade after the product is released
