• Introduction to ESPresso Lite V2.0

    Singapore's very own Wi-Fi Arduino-compatible micro-controller based on the popular ESP8266!

    ESPresso Lite V2.0 is an affordable Wi-Fi development board designed by Singapore-based IoT company, Espert Pte Ltd and manufactured & distributed by Cytron Technologies. It uses the ESP8266 chipset as the main micro-controller and supports the Arduino environment. Beginners with no experience in software programming or electronics can start building objects that can respond to light, sound, touch and movement autonomously and wirelessly (‘smart’ objects) connect them together.

    The board consists of the following distinctive features:

    • Espressif's certified ESP-WROOM-02 Wi-Fi module (which houses the popular 32-bit 80 Mhz ESP8266 SoC with 64kb RAM & 4Mb flash),
    • Two user-programmable buttons (connected to pin 0 & 13) and a reset button,
    • Green SMD LED indicator,
    • On board 3.3V Voltage Regulator with maximum current of 800mA continuous, 1A peak,
    • Input voltage Vin: 5 - 12 VDC; operating voltage at 3.3VDC,
    • Supports the Arduino IDE with own board manager and libraries,
    • Auto program loading from Arduino IDE; no manual resetting required,
    • Custom-arranged I2C pads for I2C-compliant sensors or OLED LC display,
    • Breakout pins are breadboard-friendly .

    The ESPresso Lite V2.0 is a re-designed version of the earlier ESPresso Lite that is made for the mass market. For more information about the beta or version 1 of the ESPresso Lite, please click here.

    For more information about the origin of the board, please check out the project log at Hackaday!

    Made by Singapore. Innovate with ASEAN. Sold around the world.

  • Quickstart

    From unboxing to making your first Internet connection

    Prelude

    Appreciation

    Thank you for supporting the ESPresso Lite project. The box that you receive contains the ESPresso Lite V2.0 board and its corresponding pin and headers. It will require some additional soldering work from you, O our esteemed user.

     

     

    Preparations

    Assemble and solder

    Locate the correct pins and headers prior to soldering to avoid making any mistakes. Please ensure that appropriate safety precautions have been considered before starting out.

     

    NOTE: Do not overheat the board by placing the soldering iron too long on the pin! You may damage the components.

     

    If you have not had any experience with the soldering iron, you can seek advice from a more experienced person.

    Peripherals

    Accessorize

    The ESPresso Lite V2.0 can be used as a 'bare board' or best together with additional components such as the 0.96" OLED display (shown in pic) or a DHT22 digital temperature and humidity sensor as an IoT starter kit.

     

    It is advisable to secure the board onto a breadboard for stability while working with the component.

    Powering Up

    Activate

    You can either FTDI cable or UC00A USB to UART converter to upload your program from your PC or just simply to power the board.

     

    You can use power from 3x AA/AAA batteries (4.5V), powerbanks (5V) or simply from your PC/laptop USB port (5V).

    Programming it

    And start build your latest thingamajig

    We will be using the Arduino IDE to program it. Remember to set it up by following the instructions over here.

     

     

    The default program that you will need to get you started to use the many features indicated in this tutorial is found in File > Example > ESPert > _2000_ESPert_workshop

     

     

    IoT Starter Kit

    The tutorial is also specially designed for the IoT starter kit where in addition to the ESPresso Lite V2 board, you will also be provided with the DHT22 digital humidity & temperature sensor, 0.96" 128x64C SSD1306 OLED screen as well as other peripherals like the mini breadboard and the USB-UART converter board (UC00A).
