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 β€œAllow” 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 β€œesp8266” 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.
