开发板信息

ESP-WROOM-32 是一款通用型WiFi-BT-BLE MCU 模组，功能强大，用途广泛。
    此款模组的核心是ESP32芯片，具有可扩展、自适应的特点。两个CPU 核可以被单独控制或上电。时钟频率的调节范围为80 MHz 到240 MHz。用户可以切断CPU 的电源，利用低功耗协处理器来不断地监测外设的状态变化或某些模拟量是否超出阈值。ESP32还集成了丰富的外设，包括电容式触摸传感器、霍尔传感器、低噪声传感放大器，SD 卡接口、以太网接口、高速SDIO ／ SPI、UART、I2S 和I2C 等。
     ESP-WROOM-32集成了传统蓝牙、低功耗蓝牙和Wi-Fi，具有广泛的用途：Wi-Fi 支持极大范围的通信连接，也支持通过路由器直接连接互联网；而蓝牙可以让用户连接手机或者广播BLE Beacon以便于信号检测。ESP32芯片的睡眠电流小于5 A，使其适用于电池供电的可穿戴电子设备。ESP-WROOM-32支持的数据传输速率高达150 Mbps，经过功率放大器后，输出功率可达到22 dBm，可实现最大范围的无线通信。因此，这款芯片拥有行业领先的技术规格，在高集成度、无线传输距离、功耗以及网络联通等方面性能最佳。
    ESP32的操作系统是带有LWIP 的freeRTOS，还内置了带有硬件加速功能的TLS 1.2。芯片同时支持OTA 加密升级，开发者可以在产品发布之后继续升级。
