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.

Hi, it can accept 3.3V only

Why espert smart config app and espert IoT Mobile app no longer available at playstore?

( drkronik82, 18/09/2018 )
Hi, sorry about that. Seems like they forgot to update it. We will ask them regarding this issue
Can i get the soldered espresso lite? Its hard to solder myself ( MOHAMAD NASRIZAL HAFIZI MAZLAN, 04/07/2018 )
Hi, you can contact for custom order. Thanks.
Can I use UC00C instead or recommended UC00A ? ( DS, 11/06/2018 )
Hi, yes you can. Thanks.

what arduino ide version should i use to fit esp8266 lite v2.0 ??? tq ( wawa, 05/11/2017 )
Hi, you can use the latest Arduino IDE and refer to the Getting Started Guide under Attachment tab. For further questions, please visit to our technical forum as this session is only for short inquiry related to the product. Thanks.
Hi, what the advantages of the "Espresso Lite 2.0" on the Arduino Uno card? Thank you ( nicolas, 16/05/2017 )
Hi, this ESPresso Lite V2.0 can be used independently. If you have more question please visit our forum as here is for the short inquire only. Thanks :)
Hello, I want to enquire about the Vsel setting on the UC00A board. Should I use 5V or 3.3V? And, are the TX and RX pins (also DTR and CTS) on the ESPresso 5V-tolerant? TQ ( osman, 26/04/2016 )

Hi. The operating voltage for the board is 3.3V. For UC00A VSel, you can use 5V. Thanks. :)

Can we flash or upload the code to the Espresso Lite via online IDE or something like that? The main purpose is I don't want to get the USB to UART Converter for the device. So, I'm thinking that do I really need the add-on shield to work on the board. Tq ( sasitaran, 06/04/2016 )

Hi. It is possible to upload the code without using UC00A. You can use Arduino board as USB to UART converter instead of using UC00A. For further inquiry, kindly visit our technical forum as this session is only for short inquiry. Thanks. :)

hi. can the ESPresso lite v2.0 acts as Wi-Fi shield for arduino? thanks ( naqiu, 02/04/2016 )

Hi. Yes and No. Yes it can act as Wifi Shield to Arduino. No, it is not compatible in term of hardware. You need to do the wiring. Further inquiry, kindly visit our technical forum as this session is only for short inquiry. Thanks. :)
