Hi,
Thanks for sharing this information.
How can I download circuit schematic diagram of this board?
Which LCD display - controller , Touchpad - controller exist on the board?

EDIT: A few days ago I bought an esp32-wrover-kit v4.1 with big hopes; It is an original espressif board, it has nuttx and lvgl support, good features, good value … what else I can expect ! The board came fast, I loaded appropriate nuttx configuration, run lvgldemo… hugh, the display was running up and down as seen on old time TVs, touch keypad was not working, I thought that there is something wrong in firmware, opened an issue about the strange behavior of lvgl demo, then I learned that esp32-wrover-kit does not have a touch keypad, and the lvgldemo is making a special demo ( different than others that I tried before ) because of none-existent user entry ! This was a great surprise for me, once again spending money and time to test another board. That’s why I am asking details, I am tired of testing new boards.

And everybody in this forum deserves to read and see our discussion therefore I believe it is better if you answer here.!

Many thanks for your comment. Plz visit our website below and send inquiry there.Have technical support for you.

What differs asking a question here and asking on alibaba page? Why don’t you answer right now. Here is a good place to talk about technical matters.

Sir, I quite understand your worry. We are proffesional IOT solution factory and as the Partner of Espressif Syatem. Plz don’t worry. We’re pleased to answer your all questions. But your for further question it concern about our R&D issue, so we’d better send you in private. Plus, I’m just a writer responsible for share information on LVGL. But I don’t know much about the technical issue. Wireless-Tag has strict R&D team to offer technical support for anyone inquiry from Alibaba first. And there you can contact with them more convenient.

At last, appreciate your questions again, plz kindky understand and chat via link sent. :grinning:

You could simply ask this question to somebody sitting behind you (if you don’t know where is the user manual or something) and provide us just a download link instead of writing more than 100 words.

This post was marked as spam/off-topic. I messaged to @WIRELESS_TAG and clarified that this product use 8ms GUI system which is based on LVGL so this topic is relevant in this forum.

Hi, Good Day! Understand. Plz check below reply.

  1. How can I download circuit schematic diagram of this board?

—Link as below for datasheet include circuit schematic diagram.

Agreed that this looks like vendor spam! Wireless-Tag should consider submitting the board for proper LVGL certification :slight_smile:

We have been using these boards with our own custom firmware for months. I’m using PlatformIO with Arduino-ESP32 and TFT_eSPI. It runs stock lvgl just fine without the need for the 8ms GUI website…

The configuration for TFT_eSPI can be found on our Github repo.
I compiled a small overview page in our documentation site.

The Pros of this board:

  • 3.5" 480x320 ST7796S TFT Display
  • Capacitive touchscreen FT6336U
  • 8 MB PSram
  • Fair price point
  • Expansion headers

The cons:

  • Only 4 MB flash on basic model (there is a 16MB SKU too)
  • Poor viewing angles in landscape mode
  • Mounting holes placement

Or have a look at the Wireless-Tag Github repo for their lvgl examples.
