TJC 4.3 inch HMI LCD Display Module Touch Screen Smart Serial Panel for Raspberry Pi & Arduino

Overview 

Take the heavy lifting off your microcontroller with the TJC 4.3-Inch Intelligent HMI Serial Touch Display. Unlike traditional raw TFT screens that devour your controller’s RAM and processing power to refresh color blocks, this smart display features its own embedded processor and memory stack.

Using a drag-and-drop editor on your computer, you can easily build beautiful operational buttons, live gauges, progress bars, and keypad entries. Once compiled, your Raspberry Pi, Arduino, or STM32 simply sends and receives simple text commands via a standard asynchronous serial link (UART), creating a responsive Human-Machine Interface with minimal coding.

Key Features

• Onboard Smart Processor: Handles all complex graphical rendering internally, reducing your host MCU’s software overhead to nearly zero.

• Minimalist 4-Pin Interface: Connects using only VCC, GND, TX, and RX data lines—saving dozens of valuable GPIO pins.

• Visual Drag-and-Drop Editor: Design your interface layout visually using text labels, icons, sliders, and animation components.

• MicroSD Card Storage Slot: Easily flash your compiled user interface configurations directly onto the screen without complex hardware programmers.
