Specification Brand : Hosyond BulletPoint1 : The main body of the module is ESP-WROOM-32 module, which is powerful and supports LWIP protocol, freertos. The peripheral adopts USB serial port chip CP2102 to expand the micro USB interface, which can be directly debugged by connecting to the computer through USB. BulletPoint2 : Support AP, STA, AP+STA three modes. Integrated power indicator (red light) and working status indicator (blue light), let you know the status of the module at any time. BulletPoint3 : The ESP-32 dual-mode module is compact and easy to embed into your device for your convenience. Compatible with Arduino IDE. BulletPoint4 : There are two buttons integrated, one is to reset, and the other is to make the module enter the halberd program mode. The 30 pins on both sides of the development board are convenient for developers to connect and use. BulletPoint5 : In addition, this module also supports NodeMCU Lua programming, which expands the scope of its available resources and greatly improves the convenience of learning and development. Of course, it can also be widely used in IoT occasions.
