Product description
Custom Character LCD Modules Fit For UART/RS232/USB LCD Interfaces CH204 Series Character Control Board
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.
Product Features and advantages
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.
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.
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.
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.
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.
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.
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.
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.
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.

What this specification means in practice
TN glass is the cost-efficient choice with the fastest response. Contrast and colour shift once you move off the specified viewing direction, so it fits devices with a fixed operator position.
100 cd/m² is an indoor, low-power specification - typical for battery meters and handheld instruments where runtime matters more than brightness.
The UART/serial variant carries its own controller and command set, so your MCU sends text and commands instead of driving pixels. It cuts firmware work substantially.
Operating range -20°C to +70°C covers unheated cabinets, outdoor enclosures and cold-chain equipment. Standard commercial panels stop at 0 °C and go dark or slow in the cold.
Ordering and customisation
This model ships as a bare module by default. We commonly modify the FPC length and connector, change the backlight current, add a capacitive or resistive touch panel, or bond cover glass with your printing. Tell us the enclosure opening and the mounting method and we will confirm what can stay standard and what needs tooling.
Typical applications
Industrial Automation & HMI
Status lines on controllers and drives - two or four rows of text is often the entire UI requirement.
Instrumentation & Metering
Bench equipment and test rigs where a standard 16x2 module keeps BOM cost and firmware effort minimal.
How a customised order runs
Send the requirement
Size, resolution, interface, brightness, operating temperature, touch or no touch, and the annual quantity. A photo or drawing of the enclosure opening helps more than a long description.
We confirm feasibility and quote
You get a specific model number or a modification plan, with tooling cost and lead time stated separately from the unit price. Usually within one working day.
Sample and approval
Samples in 10-15 days from stock glass; custom glass or a new FPC adds tooling time. You approve dimensions, display quality and interface timing before mass production starts.
Production and shipment
10-20 days after specification freeze. Anti-static bag + foam tray + export carton, shipped DHL / FedEx / UPS express or by your forwarder. We keep the approved sample as the reference for every repeat order.
Questions about this model
What is the minimum order quantity for the CH204 Series Character Module?
Samples are 5 pcs. Production MOQ is 100 pcs for this catalogue model and 1,000 pcs when the FPC, backlight or glass is modified.
How long is the lead time?
10-20 days for production quantities, 10-15 days for samples from stock glass. Custom tooling is quoted separately and confirmed in writing first.
Can this module be customised?
Yes - FPC length and pin order, connector type, backlight brightness and colour temperature, cover glass, touch panel and bonding method. See what is changeable.
Do you provide a datasheet and drawing?
Yes. Email hyd@szjunxian.com with the model number and we send the full datasheet, 2D drawing and, where relevant, the initial sample report.
Which interface should I choose for my board?
It depends on your host processor and target resolution. Our interface selection guide compares MCU, SPI, RGB, LVDS and MIPI by pin count, resolution ceiling and MCU load.
Packaging, shipping and trade terms
Packaging is anti-static bag + foam tray + export carton, shipped by DHL / FedEx / UPS express, air freight, sea freight. Trade terms EXW, FOB Shenzhen, CIF, payment T/T, L/C, PayPal.
Need this module with different parameters?
Most orders start from a catalogue model and change two or three parameters. Send us the differences you need and we will confirm feasibility, tooling and price.
