ESP-01 ESP-01S to ESP8266 adapter with 3.3-5V voltage regulator, 2.54 mm pitch

ESP-01 to ESP8266 adapter with voltage regulator

A convenient ESP8266 adapter designed for stable use with popular ESP-01 and ESP-01S modules. An excellent solution for microcontroller projects, including for ESP8266, for Arduino, and for Raspberry Pi.

The module has a built-in voltage regulator, so you can safely apply supply voltage in the range of 3.3V to 5V to the power pins. Standard TX and RX pins enable trouble-free communication with the module, while GND and VCC pins are used for power.
