Package include:
3 x ESP32 30pin CP2102 development board
3 x ESP32 breakout board

The esp32 breakout board has two rows of pins, 15 each, for a total of 30 pins
The module is the ESP32-DevKitC-32 module, which uses a USB to serial port chip CP2102 to expand the TYPE-C interface, support Lua program, easy to develop, support of three modes: AP, STA and AP + STA
The expansion board is a double-layer board. One pin is wired on both sides. Therefore, the circuit is stable and highly reliable, and there will be no poor circuit contact and unstable signal transmission
The esp32 module supports multiple development, expanding the available range of its resources and greatly improving the ease of learning and development. Of course, it can also be widely used in IoT applications, such as home automation, wireless industrial control, wireless positioning system signals, etc
The esp32 breakout board can expand one GPIO pin of esp32 development board to 2, convenient to reuse all pins in smart home DIY projects
