ESP32 DEV IOT development board compatible with arduino

The development board modulemodel ESP-WROOM-32 is a universal Wi Fi+BT+BLE MCU module with powerfulfunctions and wide applications, which can be used for low-power sensornetworks and extremely demanding tasks such as voice encoding, audio streaming,and MP3 decoding.

ESP-WROOM-32 integratestraditional Bluetooth, low-power Bluetooth, and Wi Fi, and has a wide range ofapplications: Wi Fi supports a wide range of communication connections and alsosupports direct connection to the Internet through routers; Bluetooth allowsusers 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 forbattery powered wearable electronic devices. The ESP-WROOM-32 supports a datatransmission rate of up to 150 Mbps, and after passing through a power amplifierand antenna, the output power can reach 20.5 dBm, achieving the maximum rangeof wireless communication. Therefore, this chip has industry-leading technicalspecifications and performs best in high integration, wireless transmissiondistance, power consumption, and network connectivity.
