2. Wi-Fi protocol: 802.11 b/g/n/d/e/i/k/r (802.11n, speed up to 150 Mbps), A-MPDU and A-MSDU aggregation, support 0.4us guard interval;
3. Wi-Fi standard: FCC/CE/TELEC/KCC frequency range: 2.4-2.5 GHz;
4. Bluetooth protocol: Compliant with Bluetooth V4.2 BR/EDR and BLE standards;
5. Bluetooth audio: CVSD and SBC audio;
6. On-chip sensors: Hall sensor, temperature sensor;
7. Support UART/SPI/I2C/PWM/DAC/ADC and other interfaces;
8. On-board PCB antenna;
9. On-board battery interface, which can be powered by battery alone;
1. The main body of the module is the ESP32-WROOM-32 module. The peripheral uses the USB to serial port chip CP2104 to expand the Micro-USB interface. It can be directly connected to the computer via USB for debugging, and the data transmission is fast and stable.
2. There are power indicator (green light) and working status indicator (red light) on the module, you can know the status of the module at any time.
3. It adopts Wi-Fi+BT+BLE MCU module, which is powerful and versatile, and can be used for low-power sensor networks and extremely demanding tasks, such as voice encoding, audio streaming, and MP3 decoding.
4. The core of the module is the ESP32 chip, which is scalable and adaptive.
5. It integrates traditional Bluetooth, low-power 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 routers; while Bluetooth allows users to connect mobile phones or broadcast BLE Beacon for easy signal detection. The sleep current of the ESP32 chip is less than 5µA, making it suitable for battery-powered wearable electronics.
6. ESP-WROOM-32 supports data transmission rate up to 150 Mbps, and after passing through the power amplifier, the output power can reach 22 dBm, which can realize the maximum range of wireless communication.
7. The module supports development environments such as for Ano, which expands the availability of its resources and greatly improves the ease of learning and development.
