Description:1. The main body of the module is ESP-WROOM-32 module, and the peripheral uses the USB serial port chip CP2102 to expand the micro USB interface, which can be directly debued by a USB connected computer, and the data nsmiion is fast and stable.2. It has power indicator (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 ons, one is reset, the other is enable module 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 obtain rich resources from Lexin and anxinco official websites.5. In addition, the module supports for NodeMCU and other development environments, which expands the range of its resources available 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, wirele industrial control, wirele positioning system signal, etc.Feature:1. The module is the ESP- WROOM-32 development board, and the ESP- WROO2 characteristic is also the characteristic of the module.2. 802.11b/g/WiFi + BT module.3.
