ESP-08 ESP8266 Remote Serial WiFi Module
ESP-08 overview
The ESP-08 is an ESP8266 Remote Serial WiFi Module. Main ratings: Working voltage 3.3V; Supported voltage 3.0 - 3.6V; Working current 71-80mA; Maximum current 500mA. This page brings together the ESP-08 pinout and key specifications, with the full datasheet PDF to preview below or download.
ESP-08 ESP8266 is a low-cost System on Chip (SoC) Microcontroller from Espressif Systems. It comes in both single-core and dual-core variations of the Tensilica’s 32-bit Xtensa LX6 Microprocessor with integrated Wi-Fi and Bluetooth. ESP-08 module encapsulation mode is diversiform and the onboard antenna can support board PCB, IPEX interfaces, and stamp holes with three distinct three forms. ESP-04 ESP8266 is used for a wide variety of applications such as in smart grid, smart transportation, intelligent power systems, handheld devices, industrial control, etc
The presence of built-in memory allows the ESP-08 to work almost autonomously and not depend on additional external microcontrollers. Structurally, the ESP-08 is a microcontroller that is directly connected to the flash memory chip integrated into the module, into which the executable sketch is flashed.
