ESP 8266 WIFI Module For Arduino And Pi ESP-01 Black ESP-8266 4MB Flash Esp8266 Serial WIFI Transceiver Module based on ESP8266 SoC. Which has an Integrated TCP/IP protocol stack. Esp 01 Esp8266 Module is a highly integrated chip designed for the needs of a new connected world.

esp01 module offers a complete and self-contained Wi-Fi networking solution, allowing it to either host the application or to offload all Wi-Fi networking functions from another application processor.

wifi module esp 01 that allows microcontrollers access to a Wi-Fi network. This module is a self-contained SOC that doesn’t necessarily need a microcontroller to manipulate inputs and outputs as you would normally do with an Arduino, for example, because the ESP-01 acts as a small computer.

ESP 8266 WIFI Module For Arduino And Pi ESP-01 Black ESP-8266 has a powerful enough onboard processing and storage capability that allows it to be integrated with the sensors and other application specific devices through its GPIOs with minimal development up-front and minimal loading during runtime.

Its high degree of on-chip integration allows for minimal external circuitry, including the front-end module, is designed to occupy minimal PCB area. The 1MB Flash ESP-01 Esp8266 Module supports APSD for VoIP applications and Bluetooth co-existing interfaces, it contains a self-calibrated RF allowing it to work under all operating conditions and requires no external RF parts.

When esp01 4mb Module hosts the application, and when it is the only application processor in the device, it is able to boot up directly from an external flash. It has integrated cache to improve the performance of the system in such applications, and to minimize the memory requirements.

Note:

The ESP8266 Module is compatible only with 3.3V logic level and will not work directly with 5V devices (for both serial and GPIO access). You need a 3.3V compatible device or you will need to convert the levels before you use it.
