## Description

Product description: ESP8266 is a highly integrated chip designed for the needs of a new connected world. 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. Note: Please contact us if you need the driver or meet any issue when using. We provide 100% satisfication service for customers. Package included: 2* HiLetgo ESP8266 NodeMCU CP2102 Development Board

## Questions & Answers

**Q: how do i get it working on osx**
A: Since I had a bit of trouble figuring this out as most of the info I found is for Windows, here are the steps to get this working with the Arduino IDE on a Mac:

1. 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.

There are a couple of instruction you can read here - https://github.com/esp8266

### ⭐⭐⭐⭐⭐ I'm using the NodeMCU as a web server and it works great. It was a struggle to find example code ...
*by F***. on 19 January 2018*



### ⭐⭐⭐⭐⭐ Best product
*by M***M on 4 October 2019*



### ⭐⭐⭐⭐⭐ Ottimo prodotto dalle molteplici possibilità
*by B***E on 9 September 2019*

Ho acquistato il microcontroller per costruire una semplice stazione meteo casalinga abbinandolo a un display da 2.8” e a un sensore BME280 sempre HiLetgo. Il tutto è arrivato in 2-3 giorni grazie al fatto che viene spedito da Amazon (ordinando da altri siti concorrenziali avrei risparmiato pochi centesimi ma avrei dovuto aspettare più di un mese perché spediti dalla Cina). Il modulo arriva confezionato con il classico sacchetto antistatico e con le strisce dei contatti già saldate (comodo per iniziare ad usare il dispositivo fin da subito). Per evitare che i piedini vengano piegati durante il trasporto sono protetti da un rettangolo di polietilene. Lo stampato e le saldature risultano di buona fattura. Il modulo e dotato di memoria flash da 4MB. Per utilizzare questi moduli con l’IDE Arduino bisogna prima configurare l’ambiente di sviluppo, operazione che si completa in pochi istanti grazie alle guide presenti in rete o sul sito del produttore hiletgo.com. Tutto funziona alla perfezione e senza nessun problema. Prodotto decisamente interessante ed economico.
