Aug 10, 2018 · ESP8266 (also called ESP8266 Wireless Transceiver) is a cost-effective, easy-to-operate, compact-sized & low-powered WiFi module, designed by Espressif Systems, that supports both TCP/IP and Serial Protocol.

ESP8266-01 Features. Low cost, compact and powerful Wi-Fi Module; Power Supply: +3.3V only; Current Consumption: 100mA; I/O Voltage: 3.6V (max) I/O source current: 12mA (max) Built-in low power 32-bit MCU @ 80MHz; 512kB Flash Memory; Can be used as Station or Access Point or both combined; Supports Deep sleep (<10uA)

ESP8266 is an UART-WiFi transparent transmission module with ultralow power consumption, specially designed for the needs of a new connected world. It 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.

The power-saving architecture features three modes of operation: active mode, sleep mode and deep sleep mode. This allows battery-powered designs to run longer. 32-bit Tensilica Processor

Understanding the ESP8266 WiFi Module schematic is crucial for troubleshooting, modification, or designing custom applications using the module. It allows developers to identify potential issues or conflicts, and make necessary modifications or additions to meet specific requirements.
