This is the common ESP-01 breadboard adapter for the ESP8266 serial-to-WiFi transceiver module.
Because the ESP-01 pinout is not bread-friendly and has no label, this makes it less convenient for rapid prototyping. This breadboard adapter will help you to do it
It is easier to use the esp-01 module prototype.
This breakthrough conveniently provides a clear lead screen print at the top and will fit well into your favorite breadboard.
Last but not least, we added a 0.1μF decoupling capacitor, so the ESP-01 will always be smooth and unimpeded.
