Custom Character LCD Modules Fit For UART/RS232/USB Lcd Interfaces CH204 Series Character Control Board
1. Definition
A Character LCD (Liquid Crystal Display) module is a display device designed to show alphanumeric characters, symbols, and simple icons. It uses predefined character patterns stored in its memory to form text-based information, typically arranged in rows and columns. Unlike graphic LCDs, character LCDs focus on presenting text rather than complex images or graphics.
2.Product Features and advantages
(1) Diverse Character Configurations:
The CH204A series comes with a wide array of character - type LCD modules, including 82, 122, 162, 202, 204, and 402 options. This allows users to pick the most suitable module according to their specific character display requirements, whether it's for simple text prompts or more complex data presentation.
(2) Rich Communication Interfaces:
It supports common interfaces such as UART (TTL), RS232, and USB (CDC_ACM, with no need for a driver). Moreover, it offers customizable options like RS485 and CAN. This extensive range of interfaces ensures seamless integration with various systems, be it industrial control setups, embedded devices, or consumer electronics, eliminating compatibility issues.
(3) Flexible Input Ports:
There are multiple input port choices available, including PH2.0, USB - micro, and USB - TYPEC. This flexibility makes the module easy to connect to different power sources and data transmission lines, simplifying the installation process and adapting to various hardware environments.
(4) Software - Adjustable Display Settings:
Users can control the backlight brightness and LCD contrast through software. This feature enables the module to adapt to different lighting conditions, whether it's in a brightly lit industrial workshop or a dimly lit embedded device enclosure, ensuring clear text visibility at all times.
(5) Memory Function for Persistent Settings:
The module has a memory function that can save startup interface characters and custom characters (0 - 8 characters) even when the power is off. This means there's no need to re - configure the display settings every time the device is powered on, improving the efficiency of device startup and operation.
(6) Versatile Command Controls:
It supports functions like automatic line - break, cursor setting (underline, blinking block), and cursor shifting, as well as escape character control. These features provide great flexibility for text formatting and dynamic display, making it ideal for applications that require interactive text output, such as user - interface displays in embedded systems.
(7) Broad System Compatibility:
The CH204A series is compatible with serial communication in Linux and Windows systems, as well as Python third - party compilation platforms. This wide - ranging compatibility allows developers to use their preferred programming environments, reducing the learning curve and accelerating the development process.
(8)Strong Electromagnetic Compatibility (EMC):
With an EFT rating of > ±4KV and an ESD rating of > ±15KV, the module has a strong anti - interference ability. It can operate stably in electromagnetic - noisy environments, such as industrial factories or near high - voltage equipment, ensuring reliable performance.
(9) Low - Power Operation:
The module operates at 5V with a current consumption of only 5mA. This low - power feature makes it suitable for battery - powered devices or applications where energy efficiency is a top priority, helping to extend the battery life of portable devices.

6. Application fields
Here are the recommended application areas for the Character LCD Modules:
(1) Industrial Control Systems:
In industrial control panels, the module's strong EMC performance, diverse communication interfaces, and flexible command controls make it an excellent choice for displaying real - time data, system status, and operation prompts. It can withstand the harsh electromagnetic environment in factories and ensure stable communication with various industrial controllers.
(2) Embedded Devices:
For embedded systems developed using Linux, Windows, or Python platforms, the module's system compatibility and low - power operation are very attractive. It can be used for displaying system information, user interfaces, or diagnostic messages in devices such as smart home controllers, IoT sensors, and small - scale industrial embedded devices.
(3)Consumer Electronics:
In consumer electronics products like portable gadgets, digital assistants, or small - scale home appliances, the module's low - power consumption, flexible input ports, and adjustable display settings can provide clear text display while saving energy and adapting to different usage scenarios.
(4)Automation Equipment:
In automation equipment such as CNC machines, robotic control panels, or assembly line monitors, the module's command controls for text formatting and dynamic display can be used to show operation instructions, error messages, and production data, improving the usability and maintainability of the equipment.
(5) Medical Devices (with Appropriate Requirements):
In some medical devices that require simple text display, such as patient monitors (for basic parameter display) or medical test equipment (for result indication), the module's reliability, low - power operation, and clear display can meet the basic display needs, provided that the device's overall design and regulatory requirements are met.
