The ESPresso Lite V2.0 Arduino ESP8266 WiFi Module is the first low-cost Arduino-compatible ESP8266 Wi-Fi development board to be manufactured that allows anyone to learn experiment and build their IoT projects easily and quickly
Features Espressif System's ESP8266 WROOM-02 Wi-Fi module
Design for IoT with free espert.io cloud and app service
Support the Arduino IDE (boards manager) and libraries
Auto program loading from Arduino IDE
The core hardware inside ESPresso Lite V2.0 is Espressif System's ESP8266 WROOM-02 Wi-Fi module and is programmable using the Arduino IDE like how anyone would run their programs in other Arduino boards.
ESPresso Lite V2.0 comes in a kit, with extra headers. You will have to fire up soldering station to solder some of the headers. Not to forget we recommend getting Cytron USB to UART Converter for USB to UART which you need to load program and future debugging purpose.
