Any advice for buying a cheap touchscreen TFT 3.5"" ...

Read Bodmer's posts. After all, TFT_eSPI library was written by Bodmer.

For more information, please visit our website.

(1) is a horrible kludge.
(2) is out of your price range by the time you have added all the "extras"

(4) and (5) have no photos of the pcb. I would like to see what access there is for IM# pins.
Bodmer does not support R or RM.
(6) is expensive.

If you want to go for bare TFT modules, there will be several on AliExpress.

Quite honestly. Most cheap boards are -16 or -8 without any access to IM# pins.

STM32 Embedded Display - 5-inch TFT LCD screen

Description

High performance
STM32 MCU

The STM32U5 series offers advanced power-saving microcontrollers, based on Arm® Cortex®-M33 to meet the most demanding power/performance requirements for smart applications, including wearables, HMI, personal medical devices, home automation, and industrial sensors.

Offering up to 4 Mbytes of flash memory (dual bank) memory and Kbytes of SRAM, the STM32U5 series of microcontrollers takes performance to the next level with advanced graphics capabilities.

The STM32U5 series provides greater integration and memory capabilities to maximize performance. Ultra-low power, it is the first 32-bit MCU embedding a flash memory, up to 4 Mbytes.

 

 

 

Multi-Interfaces

RS485

Expansion connector

The board offers additional and independent GPIOs over a 40pin, 1.27mm female socket. It provides direct access to the below GPIOs of MCU, that makes it possible to be easily extended by an addon board for specific application.
List of interfaces on Expansion connector:
2 x I2C, UART, USART, SPI, USB, 7 x PWMs, 1 x DAC (Digital-to-analog), 2 x ADCs (Analog-to-digital)

Fully independent CAN FD

Applicable in industrial and automotive area.

USB

Can be configured to both Host and Device.

Micro-SD card slot

Another external storage. Supporting uSD card type: SD, SDHC, SDXC cards.

ORIC Electronics are exported all over the world and different industries with quality first. Our belief is to provide our customers with more and better high value-added products. Let's create a better future together.

Fast-programming SWD port

SWD connector allows to program STM32 and QSPI with customer&#;s applications. Riverdi developed the ST-LINK programming cable that is included in the STM32 Embedded Display sample package (single packing).

RiBUS

In some applications there might be a need to connect a second display in one device. With the STM32 Embedded Display line it is very easy as these displays are equipped with Master RiBUS connector &#; universal interface to Riverdi&#;s intelligent displays. In this way, the second display does nots need an external host controller and 2 independent displays can be controlled by one STM32.

Wide input supply range

Power supply voltage ranges from 6.0 V- 48.0V. A wide power supply comes with a wide range of application. Reverse polarity protection which ensures the device is not damaged if the power supply polarity is reversed. The module also can be powered from interface connectors: RS232, RS485, 2xCAN FDs. They are internally connected.

 

Low EMI design

STM32 Embedded boards were designed with special attention paid to electromagnetic compatibility, a design that has given them a high immunity to external electromagnetic signals which otherwise could have disturbing influence on their working correctly.

Board is equipped with low noise backlight converters thanks to which they produce low electromagnetic interference (EMI) to the surrounding space. In consequence, external electronic devices or circuits do not need special electromagnetic screening.

The EMC measurements held in a specialized laboratory confirmed low electromagnetic emissions of STM32 Embedded modules, even when displaying dynamic pictures.

High brightness, IPS TFT

Typical surface luminance for a high brightness, IPS TFT displays is 800 up to cd/m² which means it is very bright even outdoors. The full viewing angles allow the user to interact with the display in a natural and intuitive way from every side. Please see the datasheet for more features.

Customized displays

You can customize displays in many different ways.

  • Change the color, shape, and size of the cover glass
  • Have your logo printed on the cover glass (or any other graphics you might need)
  • Add a different interface
  • Enhance the brightness of the screen
  • Change the thickness of the cover lens for the CTP
  • Choose a different viewing angle of the display
  • Change the pinout
  • Request different gasket assembly

 

As you can see the possibilities are endless. All you need to do is choose.

We will help you to get the perfect tailor-made product.
