AI-Thinker Co.,Ltd 1. Preambles ESP-08S WiFi module is developed by encapsulates Tensilica L106 integrates industry Clock speed support 80 MHz, 160 MHz, supp ESP01/01S RELAY MODULE TUTORIAL: Description This WiFi relay based on AI-Thinker ESP-01/ 01S WiFi module, we use the GPIO0 of ESP-01/ 01S to control the relay by low level. It's easy to DIY your smart switch to any device by your phone anywhere with this smart relay.Specifications En el siguiente esquema te muestro un ejemplo. Te explico ahora cómo conectar cada uno de los pines del ESP-01: Conectamos todas las masas a un mismo punto: la del ESP-01, fuente de alimentación y convertidor USB serie. El GPIO2 lo dejamos al aire: ya tiene una resistencia pull-up que mantendrá el estado a alto (HIGH) The ESP8266 ESP-01 is a Wi-Fi module that allows microcontrollers access to a Wi-Fi network.This module is a self-contained SOC (System On a Chip) 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.Depending on the version of the ESP8266, it is possible to have up. The ESP-01 module that i used originally came with older AI Thinker firmware, which limits its capabilities since many useful AT commands are not supported. It is generally a good idea to upgrade your firmware for bug fixes and also depending on the functionalities needed from the ESP module, a more complete set of supported AT commands might be required

2.2 ESP Wi-Fi module: ESP-07 Wi-Fi module is developed by Ai-thinker Team [5]. The Core processor ESP8266 in smaller sizes of the module encapsulates Tensilica L106 integrates industry-leading ultra low power 32-bit MCU micro, with the 16-bit short mode, clock speed support 80 MHz, 160 MHz, supports the RTOS, integrated Wi-Fi MAC/BB/RF/PA/LNA, on-board antenna Bare-bones AI Thinker boards If you want to add an ESP8266 to a small project, or if you want a cheaper* board, you might want to buy a board that doesn't have these features. In that case, you can buy one of the many ESP-## modules developed by AI Thinker. They contain just the ESP8266 and the necessary components to run it Successor. ESP32. The ESP8266 is a low-cost Wi-Fi microchip, with built-in TCP/IP networking software, and microcontroller capability, produced by Espressif Systems in Shanghai, China. The chip first came to the attention of Western makers in August 2014 with the ESP-01 module, made by a third-party manufacturer Ai-Thinker

El fabricante AI-Thinker proporciona la serie ESP con diferentes modelos para diferentes usos. A parte han ido surgiendo diferentes placas que incorporan algún módulo ESP como el NodeMCU. ESP-01.
