Espresso Lite V2.0: the WiFi development board for IoT devices

Description

The Espresso Lite V2.0 is a low-cost development board compatible with Arduino, based on the ESP8266 WROOM-02 WiFi module from Espressif Systems. With this board, you can create IoT (Internet of Things) devices and connect them to the cloud at www.espert.io, as well as develop custom applications.

The board is programmable via the Arduino IDE and requires a USB-to-serial converter to upload programs. It features 4 MB of flash memory, 11 I/O pins, a 3.3 Vdc voltage regulator with a maximum continuous current of 800 mA, a reset button, and two user-programmable buttons.

The board’s pins are breadboard-compatible, and pins for an I²C OLED display are also present. Additionally, the Espresso Lite V2.0 has built-in WiFi connectivity, making it easy to connect to a wireless network and send data to or receive data from the cloud.

Thanks to its features, the Espresso Lite V2.0 is an excellent solution for anyone who wants to learn, experiment, and build low-cost IoT devices without sacrificing flexibility and Arduino compatibility. Moreover, the built-in WiFi connection and OLED display pins make it ideal for projects that require real-time data visualization.
