ESP-01 Adapter 3.3-5 V
Don’t send 5 V signals to your ESP8266. The use of an ESP8266 with Arduino requires logic level translation of the UART signal, as provided by this easy 3.3 V – 5 V adapter. It makes the ESP-01 ESP8266 WiFi module (150445-91) the easiest WiFi transceiver for your Arduino (5 V).
