What's HMI/UART Display?

HMI+UART Display is a display solution that combines a human-machine interface with UART communication capabilities.

In addition to a controller,our HMI display also incorporates MCU functionality. The MCU receives commands sent from the main control board (client-side)via a UART interface and then displays text, images, or animations based on these predefined instructions. The MCU on the main control board(client-side) does not require complex programming or execution specifically for image display. You can use our GUI Design software - UI Editor to create text, images, or animations easily. No programming skill is needed.

Features of HMI/UART Display

1-High Quality

ER-TFT040-3- is 4 inch 480x480 HMI display utilize vivid full-view IPS panels with high- brightness backlight, and for anti-interference purposes, MCU is enclosed within shielding cover.

2-Various Options

If the communication distance is too long for a UART interface, customers can choose RS232 or RS485 communication interfaces instead.

For touchscreens, customers can select from non-touch and capacitive touchscreens.

Contact us to discuss your requirements of 4 5 inch uatr tft lcd. Our experienced sales team can help you identify the options that best suit your needs.

We also provide accessories such as louder speakers, rotary encoders, USB cables, SD cards, and debugging boards for customers to choose from.

3-Save Time&Cost

Without the need for touchscreen debugging or programming skills, customers can easily create a touch-enabled UI interface with rich graphics and texts using our provided GUI design software- UI Editor to saving customer's development time.

The pricing of this HMI Display is the same as that of a regular LCD module to save cost.

Features of our services

1-Free Design

If you don't have time to learn how to use the UI Editor, we can help you make the UI interface you need. A new project will charge a design deposit based on the number of pages and widgets, and the entire design deposit will be refunded if the purchase amount reaches the standard.The images used in the UI are provided by the client. If our company provides the images required for the UI, there will be additional charges.

2-Open-source Project

3-3D CAD Model

In addition to datasheets, we have also prepared 3D drawings for all HMI displays, which offer a visual and three-dimensional display of the product's shape, dimensions, and structure, enabling seamless integration with your products during the design phase.
