Espresso Lite V2.0 is the first development board low-cost Arduino compatible, based on WiFi module ESP8266 WROOM-02 Espressif System. This card allows anyone to learn, experiment and build devices IoT (Internet of Things) with cloud www.espert.io and App service.

It can be programmed using the Arduino IDE and requires a USB-to-serial converter to load the program. It has 4MB of flash memory, 11 I / O, the voltage regulator to 3.3 Vdc with a maximum of 800 mA continuous current, a reset button and two user-programmable buttons, pins and pin compatible with the breadboard for OLED I²C.
