Product DescriptionDescription: 1. The main body of the module is the ESP-WROOM-32 module, and the peripherals use the USB serial port CP2102 to expand the micro USB interface, which can be directly debugged by a USB connected computer, and the data transmission is fast and stable. 2. It has power (red light) and working status indicator (blue light) on it, so you can know the status of the module at any time. 3. There are two touch buttons, one is reset, the other is the activation button to enter the halberd program mode. In addition, the pins on both sides of the development board are convenient for developers to connect and use. 4. The module has powerful Bluetooth compatible and WiFi functions. As a Bluetooth compatible and WiFi development board, it can get rich resources from the Lexin and anxinco official websites. 5. In addition, the module supports NodeMCU and other development environments, which expands the range of its available resources and greatly improves the ease of learning and development. Of course, it can also be widely used in Internet of Things occasions, such as home automation, wireless industrial control, wireless positioning system signal, etc. Function: 1. The module is the ESP-WROOM-32 development board, and the ESP-WROOM32 parameter characteristics are also the parameter characteristics of the module. 2. 802.11bgWiFi + BT module. 3.
