[Introduction]:The E103-W12C-TB wireless module test kit is an entry-level development board for two serial port WiFi modules, using the E103-W12C module named for its ultra-low power consumption. This development board has complete Wi-Fi functions, and most of the module pins on the board have been led to pin headers on both sides. Developers can easily connect a variety of peripheral devices through jumpers according to actual needs, and can also Plug the development board into the breadboard and use it.
