This is a card adapter for the ESP-01 model of the ESP8266 serial-to-WiFi transceiver module. As the ESP-01 pin arrangements are not compatible with the display card and are not suitable. This esp-01 card adapter will help you make prototyping with the esp-01 module much easier. This adapter adapts perfectly to your favorite breadboard. Last but not least, we added a 0.1 µF decoupling capacitor so that the ESP-01 always works smoothly.
