WHAT IS ESP 8266/ESP 32
What are ESP Microcontrollers, ESP8266 VS ESP 32,ESP is a series of low-cost, low-power systems on a chip microcontroller
ESP is created and developed by Espressif Systems, a Shanghai-based Chinese company, and is manufactured by TSMC using their 40 nm process.ESP is a series of low-cost, low-power systems on a chip microcontroller with integrated Wi-Fi and dual-mode Bluetooth
ESP 8266
The ESP8266 is a low-cost Wi-Fi microchip, with built-in TCP/IP networking software, and microcontroller capability This small module allows microcontrollers to connect to a Wi-Fi network and make simple TCP/IP connections using Hayes-style commands.
