ESPresso Lite V2.0 is the first low-cost Arduino-compatible ESP8266 WiFi development board to be manufactured in Malaysia. Working together with ESPert, a Singapore IoT technology company, this board allows anyone to learn, experiment and build their IoT projects easily and quickly. Cytron Technologies as the manufacturing partner is excited to announce the design of V2.0 is finalized and the pre-launch promotion is also ended. 1st batch of ESPresso Lite has been shipped out to customer early of March 2016.

The core hardware inside ESPresso Lite V2.0 is Espressif System's ESP8266 WROOM-02 WiFi module and is programable 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 UC00A for USB to UART which you need to load program and future debugging purpose.

ESPert is working hard to prepare the tutorial to kick start your first IoT project with ESPresso Lite, please refer to the this tutorial to get started.
