Hot Display Mid-March 2025 Newsletter Focus Information
Welcome to the mid-March 2025 Hot Display newsletter!
In this issue of the newsletter, we will share a USART serial port screen module (based on the STM32 core), with industry-level high-reliability display, minimal development, and intelligent control. Let's stroll through the world of display and start exploring the latest products.
STMicroelectronics STM32 serial port screen module: display screen + test motherboard + adapter board introduction
1. Module composition structure: The module consists of a 7.0-inch full-view TFT connected to a transfer board, which transmits signals to the core board with an STM32 chip, making the display intelligent.
2. Function: This is an HMI (human-machine interface) display with a system program. It has its own solution and can add functions such as storage card and Flash.
3. Spare parts: The mainboard has a core board + power boost module + backlight boost module + metal iron frame (each board can be sold separately)
Core Advantages
Industrial-grade stability, no fear of harsh environments
Equipped with STMicroelectronics STM32 industrial-grade MCU, it supports -30℃~80℃ wide temperature operation**, passes EMC anti-interference certification, and adapts to complex industrial scenarios such as high temperature, high humidity, and vibration.
Ultra-low power consumption design and dynamic power management technology extend the battery life of the device, and the standby power consumption is less than 1mA, meeting the battery power supply requirements of smart meters and other devices.
Touch integrated, cost reduction
Integrated capacitive/resistive touch driver, no need for external touch chip, simplified PCB layout, and reduced hardware cost by more than 20%.
Supports multi-touch (optional), sensitive response, strong anti-interference, and adaptable to special operating environments such as gloves and wet hands.
Open ecosystem, double the development efficiency
Provides a full-featured SDK development package, including communication protocol library, HMI interface design tools and sample code, and supports Lua script/C language secondary development.
Drag-and-drop UI design tool, you can quickly customize the interface without any code foundation, and the development cycle is shortened to 3 days.
Accurately adapt to the scene
Industrial HMI: Applicable to PLC control panels and production line equipment monitoring screens, supports Modbus protocol, and real-time data interaction is stable and reliable.
Smart meters: Suitable for embedded devices such as electricity meters, water meters, and gas meters. Low-power design helps increase battery life by 30%.
Smart home central control: 7-inch high-definition screen (800×480 resolution), with integrated touch, to create interactive terminals for home appliance control and security monitoring.
Customer Value
Plug and play: UART serial communication, compatible with mainstream industrial control motherboards, no need for complex debugging.
Fast delivery: The first batch of 7-inch screens is in mass production, and samples support 24-hour rapid application, and production is put into production after verification.
Flexible expansion: SPI and RGB interfaces are available, and 5~10-inch multi-size customization is supported in the future.
