The development board module model ESP-WROOM-32 is a universal Wi Fi+BT+BLE MCU module with powerful functions and wide applications, which can be used for low-power sensor networks and extremely demanding tasks such as voice encoding, audio streaming, and MP3 decoding.
ESP-WROOM-32 integrates traditional Bluetooth, low-power Bluetooth, and Wi Fi, and has a wide range of applications: Wi Fi supports a wide range of communication connections and also supports direct connection to the Internet through routers; Bluetooth allows users to connect to their phones or broadcast BLE Beacon for signal detection. The sleep current of the ESP32 chip is less than 5 µ A, making it suitable for battery powered wearable electronic devices. The ESP-WROOM-32 supports a data transmission rate of up to 150 Mbps, and after passing through a power amplifier and antenna, the output power can reach 20.5 dBm, achieving the maximum range of wireless communication. Therefore, this chip has industry-leading technical specifications and performs best in high integration, wireless transmission distance, power consumption, and network connectivity.
