Esp8266mod Ai Thinker For Mac Sierra

NodeMCU is an open-source firmware and development kit that helps you to prototype or build IoT products. It is based on the lowest cost WI-FI MCU ESP8266, ESP8266 is about $2 and once it comes as NodeMCU easy to prototype development kit you can purchase for about $4 something you can connect to your USB and start playing with it. We provide the best platform for IoT application development at the lowest cost.

Overview ESP8266 AT Firmware, officially launched by Espressif, is available for download and can be used directly. Also, users may find AT Project that Espressif specially created for users to customize AT firmware. This document introduces how to customize AT firmware and download AT firmware into flash.

MCU Definition

MCU stands for MicroController Unit - which really means it is a computer on a single chip. A microcontroller contains one or more CPUs (processor cores) along with memory and programmable input/output peripherals. They are used to automate automobile engine control, implantable medical devices, remote controls, office machines, appliances, power tools, toys etc.

There are two common variations of NodeMCU: v0.9 and v1.0. We will support only v1.0 for the rest of the documentation (for now at least) - so we highly recommend version 1.0 as it has more convenient dimensions to work with. This is what NodeMCU v0.9 vs v1.0 look alike - v1.0 is narrower for 2 breadboard pins then v0.9. This is the main reason why we recommend it (besides being newer, better, smarter version :)

ebay.com and other retail

If you are buying it on eBay you will often see NodeMCU v0.9 listed as 'NodeMcu Lua ESP8266 CH340G or CH340, but the better way to make sure you are buying right thing is to look for square CP2102 USB to UART Bridge.

Example of NodeMCU v1.0 - USE THESE

Example of NodeMCU v0.9 - DO NOT USE THESE

To clarify: All other esp8266 based MCUs are working fine, however, this tutorial was written based on NodeMCU v1.0 and with any other variation you will have to improvise on your own.

The first step is to install drivers.

These are drivers that can communicate to that little square chip (CP210x USB to UART Bridge VCP) we mention before:

• Choose the right version depending on your operating system
• Click on 'Download VCP' link
• Download it to the desired folder
• Double click on it after the download is done
• Extract content of the archive
• Choose the right installation depending on your operating system (x64 for 64-bit operating systems and x86 for 32-bit operating system)

• Double click on it
• Install driver
