tft display with esp32 for sale

A beautiful 3.5” touchscreen display, based on ESP32-WROVER, with a built-in 2M pixel OV2640 camera, makes it an ever perfect platform for your ESP32 projects.

Makerfabs ESP32 3.5” Touch with camera is absolutely open for makers, and besides, Makerfabs provide plenty of Demos to help the users on the usage. Have a try at this fantastic display in your next ESP32 project!~

The Makerfabs 3.5 inch TFT Touch is great but the refresh rate is always a problem, some customers feedback they want a higher speed display. But as the ESP32 has limited pins, we do not have a good way for that, until we find the ESP32-S2, which do not have BLE(compares to ESP32), but more pins, right for such a parallel TFT.

This 3.5" 320x480 TFT LCD driver is ILI9488, it uses 16bits parallel line for communication with ESP32-S2, the main clock could be up to 20MHz, making the display smooth enough for video displays. With this display, you can freely to create more IoT display projects, check the demo project in the video:

Besides, there 2 onboard Mabee pins(A I2c and an IOs) with the breakout connectors, to connect the ESP32-S2 display with sensors/ actuators, suitable for IoT applications.

The Makerfabs 3.5 inch TFT Touch is great but the refresh rate is always a problem, some customers feedback they want a higher speed display. The ESP32-S2 Parallel TFT has a much higher refresh rate, but the disadvantage is the lack of Bluetooth...

That is why this latest ESP32-S3 Parallel TFT, compares to the S2 version, not only more SRAM and ROM, the Bluetooth 5.0 make it fit for applications such as local monitoring/controlling.

With this display, you can freely to create more IoT display projects, check the demo project in the video.

Same as the S2 version, there 2 onboard Mabee pins(A I2c and an IOs) with the breakout connectors, to connect the ESP32-S2 display with sensors/ actuators, suitable for IoT applications.

I don"t actually have a display at present. I purchased a 7in one some months ago. It had an LT7381 controller and was supplied with a Hunda LT7381 library for Arduino and some basic display design software. However, I couldn"t get the hardware to work despite it being described as Arduino compatible. As it turned out, it also didn"t display anything when used with the supplied USB adaptor and design software for the PC, so it may have been faulty anyway. I posted something at the time but the controller is quite new and there was not much feedback. I ended up sending it back and getting a refund although it still cost me to send it back to china.

The reason I posted was because the project is now at the stage where the LCD display really needs to be added and I intended to get advice before making another purchase. In the meantime I have been working on the project using a 20x4 display.

Thank you for that information. Since I am using an ESP8266, it sounds like I need to look for a board that uses SPI for the display. From what I can tell, it seems that some of the cheap ones from china only use SPI only for the SD card which further confuses things.

I don"t posses an Arduino shield which is why I was trying to ascertain whether I need something like that. What is their purpose? A lot of photos show the display plugged into one and then into typically a Mega 2560. I don"t understand what the purpose of the shield is? Is it just a convenient way to provide a means of fitting the board to an Arduino with level shifting? SPI needs only 4 wires. Can"t these be connected directly to the ESP SPI pins?

OpenArduino IDE,findTFT_eSPIin the file, and for example, theT-Displayfactory test program is located atTFT_eSPI -> FactoryTest, you can also use other sample programs provided by TFT_eSPI 3 In theArduino IDEtool options, select the development boardESP32 Dev Module,select Disable in the PSRAM option,select 4MB in the Flash Size option, Other keep the default

In this guide we’re going to show you how you can use the 1.8 TFT display with the Arduino. You’ll learn how to wire the display, write text, draw shapes and display images on the screen.

The 1.8 TFT is a colorful display with 128 x 160 color pixels. The display can load images from an SD card – it has an SD card slot at the back. The following figure shows the screen front and back view.

This module uses SPI communication – see the wiring below . To control the display we’ll use the TFT library, which is already included with Arduino IDE 1.0.5 and later.

The TFT display communicates with the Arduino via SPI communication, so you need to include the SPI library on your code. We also use the TFT library to write and draw on the display.

In which “Hello, World!” is the text you want to display and the (x, y) coordinate is the location where you want to start display text on the screen.

The 1.8 TFT display can load images from the SD card. To read from the SD card you use the SD library, already included in the Arduino IDE software. Follow the next steps to display an image on the display:

Note: some people find issues with this display when trying to read from the SD card. We don’t know why that happens. In fact, we tested a couple of times and it worked well, and then, when we were about to record to show you the final result, the display didn’t recognized the SD card anymore – we’re not sure if it’s a problem with the SD card holder that doesn’t establish a proper connection with the SD card. However, we are sure these instructions work, because we’ve tested them.

In this guide we’ve shown you how to use the 1.8 TFT display with the Arduino: display text, draw shapes and display images. You can easily add a nice visual interface to your projects using this display.

ESP32 TouchDown is complete solution for anyone who wants/needs an ESP32 with capacitive touchscreen. It also has battery management onboard, a piezo speaker, and an SD card reader. ESP32 TouchDown works out of the box with the Arduino IDE, providing you have installed the ESP32 Arduino Core. Pins that are not used by the peripherals onboard are broken out.ESP32-WROOM-32D

The ESP32 TouchDown is designed with FreeTouchDeck (https://github.com/DustinWatts/FreeTouchDeck) in mind. The ESP32 TouchDown is the one stop solution to get a FreeTouchDeck up and running with capacitive touch without the need to buy separate modules. ESP32 TouchDown"s are shipped to you with the most current release of FreeTouchDeck installed! Off course you can always re-flash it with your own firmware.

The ESP32 TouchDown can be used for more the FreeTouchDeck alone. It is a fully featured DevKit. In the Github repository you will find some examples to get you started:An example for controlling Home Assistant (using their API)

The ESP32 TouchDown can run of a Li-Po battery. Combined with WiFi and BLE this makes the ESP32 TouchDown very portable. It uses an MCP73831 Charge Management Controller set to a charge current of 330mA. Charging is done through the USB-C port (using 5V). The on/off switch doesn"t effect the battery charging. So even when the ESP2 TouchDown is off, you can still charge the battery. When the ESP32 TouchDown is plugged in to USB, it will use USB power over battery power and will switch to battery power when USB is disconnected, without interrupting the ESP32.

Although the bare board looks great (if I do say so myself), there is a design for a nice slick case available on the Github repository. There are a few different backs to support a case without battery, with battery, and a FreeTouchDeck style case. You can find the case here: https://github.com/DustinWatts/esp32-touchdown/tree/main/Case

The TFT backlight anode (positive supply) is selectable via a jumper on the back. You can either power it directly from 3.3V or use GPIO32. By default, the positive source is 3.3V. You can change this and use PWM to control the backlight brightness. If you choose to have your ESP32 TouchDown shipped with FreeTouchDeck, the jumper will already be set so you can dim the backlight from the software.

ESP32 TouchDown comes ready to use. It includes all features that you would need additional modules for when using a development board. Besides that, ESP32 TouchDown is fully open source. All hardware designs can be found in the Github repository. ESP32 TouchDown is also OSHWA cerftified. You can find more information here: https://certification.oshwa.org/nl000004.html
