It offers a complete and self-contained networking solution, allowing it to either host the application or to offload all networking functions from another application processor. Instruction & Steps of How to use: 1. Download the Arduino IDE, the latest version. 2. Install the IDE 3. Set up your Arduino IDE as: Go to File->Preferences and copy the URL below to get the ESP board manager extensions: http://arduino.esp8266.com/stable/package_esp8266com_index.json Placing the http:// before the URL lets the Arduino IDE use it...otherwise it gives you a protocol error. 4. Go to Tools > Board > Board Manager> Type "esp8266" and download the Community esp8266 and install. 5. Set up your chip as: Tools -> Board -> NodeMCU 1.0 (ESP-12E Module) Tools -> Flash Size -> 4M (3M SPIFFS) Tools -> CPU Frequency -> 80 Mhz Tools -> Upload Speed -> 921600 Tools-->Port--> (whatever it is) 6. Download and run the 32 bit flasher exe at Github(Search for nodemcu/nodemcu-flasher/tree/master/ at Github) github.com/nodemcu/nodemcu-flasher/tree/master/Win32/Release Or download and run the 64 bit flasher exe at: github.com/nodemcu/nodemcu-flasher/tree/master/Win64/Release 7. In Arduino IDE, look for the old fashioned Blink program. Load, compile and upload. 8. Go to FILE> EXAMPLES> ESP8266> BLINK, it will start blinking.

Download the Mac VCP drivers at https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers 2. Install the drivers, and make sure you authorize any security prompts that appear while installing 3. (On recent macOS releases) Open System Preferences > Security & Privacy > General. You’ll see a message about the Silabs driver being blocked at the bottom. Click “Allow” 4. Download and install the Arduino IDE 5. Open Arduino Preferences and paste the URL below in Additional Board Manager URLs: http://arduino.esp8266.com/stable/package_esp8266com_index.json 6. Go to Tools > Board > Board Manager> Type “esp8266” and download the Community esp8266 and install 7. Set up your chip as: Tools > Board > NodeMCU 1.0 (ESP-12E Module) Tools > Flash Size > 4M (3M SPIFFS) Tools > CPU Frequency > 80 Mhz Tools > Upload Speed > 921600 Tools > Port > /dev/cu.SLAB_USBtoUART (leave the rest as-is) 8. Open File > Examples > ESP8266 > Blink 9. Compile and Upload. After it's done uploading, the red led should start blinking in your board. **Q: How many output amps can this handle?** A: The AMS1117-3.3 chip (3.3v regulator) looks like it has a maximum load of 1.5A. So that minus whatever the ESP itself draws. To be on the safe side, I'd limit the current draw off the 3.3v supply to around 500mA. **Q: Is there a built-in micro sd card? (description says it does, but the two units i received don't seem to have a slot for inserting an sd card).** A: I think you might be reading the description wrong. It does say "Built-in Micro-USB" and that is not the same as micro sd. I have not seen a description stating it supports a micro sd. **Q: What firmware or program is already onboard? when i connect at 115200 baud it shows the nearby ssids, but i don't know how to send commands.** A: If you only see nearby SSIDs, it means that your board has the "WiFiScan.ino" load on the board. You can see the source here - https://github.com/esp8266/Arduino/blob/master/libraries/ESP8266WiFi/examples/WiFiScan/WiFiScan.ino "AT" commands won't do you any good since it is not loaded.
