Hardware Setup:

Espresso Lite V2.0 

ESPresoo Lite V2 Package

¬† ¬†–USB to UART Converter¬†

DHT22 Temperature and Humidity Sensor

¬† ¬†–I2C Oled Module – Blue

Getting Started                                                  

Step 1

Connect to the internet by using AP mode(access point) method.


Asemble the Oled screen to the Espresso Lite v2.0 at 3v3,GND,SCL and SDA as the picture show: 


Step 3

Press the button of GPIO13 for a few second until the Espresso Lite v2.0 restart, to switch the mode to the AP mode.

  • Long blinks¬†: SmartConfig mode
  • No flash: Connected to Wi-Fi
  • Short blinks: AP mode
  • Normal blink: Trying to connect to Wi-Fi
  • No flash: Not connected to Wi-Fi



Step 4

The Espresso Lite v2.0 now as a access point,so connect the access point  ,the SSID of the access point will show in hexcedecimal number.Convert the number of the Oled screen show to hexcedecimal,and you will get the SSID.


Step 5

Open Internet browser and insert the IP address

Step 6

A box will appear ,choose one of the Wifi network  and press Enter.

Note: **After pressing Enter, press the button GPIO13 till the Oled screen reset. If the Espresso Lite v2.0 not connected please repeat the step or choose the other network.


Step 7

When the Oled screen show “Success”,that mean the network is connected with ur device.






Getting Started Espresso Lite v2.0 with Arduino IDE

Step 1

Install or update Arduino IDE v1.6.8

Step 2

Click on file->Prefereces->Settings->Additional Boards Manager URLs

Step 3

Copy the¬† into the colume of¬†Additional Boards Manager URLs and clink “OK”.



Step 4

Next,click on Tools->Board->Boards Manager,install the esp8266 by ESP8266 Community latest version.



Step 5

After install ,again go to board and click on Espresso Lite v2.0.

Step 6

After that, go to Sketch->Include Library->Manage Library,search the library below and install it.



Note: **Make sure you have installed the LATEST version for these libraries!


Or you can install it from github,click the link of each library to download the zip file.

How to install library from github manually?

Step 1

Download the zip file library from github and save to a folder.


Step 2

Go to Sketch->Include Library->Add.ZIP Library


Step 3

Select your zip file and open it.So the library will install in your Arduino IDE 1.6.8.


You may try other example.


Have Fun!
