Esp8266 Esp-01 Datasheet |verified| ✦ Limited Time

The ESP8266 ESP-01 can be programmed using a range of development tools, including:

⚠️ Do use 5V logic levels. Use a level shifter or voltage divider for 5V UART signals. esp8266 esp-01 datasheet

The ESP8266 ESP-01 is a powerful and versatile Wi-Fi module that offers a range of features and applications. With its low power consumption, high integration, and programmability, it has become a popular choice for IoT and electronics projects. By understanding the ESP8266 ESP-01 datasheet, developers and makers can unlock the full potential of this module and create innovative and connected devices. The ESP8266 ESP-01 can be programmed using a

The pinout is the most confusing part of this module. There are two versions: (original) and ESP-01S (revised). They look identical but have different internal pull-up resistors. With its low power consumption, high integration, and

Before the ESP8266, adding wireless connectivity to a microcontroller project was expensive and complex. The ESP-01 changed the game by offering a full TCP/IP stack and 802.11 b/g/n Wi-Fi for less than $5.

The ESP-01 is not breadboard-friendly out of the box. Because its pins are spaced 2.54mm apart but in a single row, you cannot plug it directly into a standard breadboard. You will need a breakout adapter or an ESP-01 programmer board.

Many beginners try to power the ESP-01 from an Arduino Uno's 3.3V pin. because the Uno’s onboard regulator can only supply ~150mA. The ESP-01 can spike to 300mA when transmitting Wi-Fi. This causes a brown-out reset (constant rebooting).
