Smart Serial UART HMI Display Modules
5 models from 2.8" to 4.3", with UART serial and RGB parallel interfaces. Samples 5 pcs, lead time 10-20 days. A smart module carries its own controller: your MCU sends commands or text over UART instead of driving pixels. It costs more per unit than a bare panel and saves weeks of display firmware. Our BMS variants ship with a battery-monitor command set already implemented, which is why energy-storage customers use them for retrofits.

How to choose
Do you need a smart module at all?
If your MCU already drives a panel and has spare cycles, a bare TFT is cheaper. If display firmware is the bottleneck, a smart module pays for itself.
Which protocol?
Our BMS variants implement a battery-monitor command set. For other applications we adapt the command table to your data model.
UI design
Send the screens you want; we load the assets and expose them as commands, so the host only sends values.
Still unsure? The technical guides go through these decisions with numbers, or send us the application and we will shortlist two or three models.
Smart Serial UART LCD Modules - common questions
What is the MOQ for smart serial uart lcd modules?
Samples 5 pcs, standard production 100 pcs, fully custom 1,000 pcs.
Can I get a datasheet before ordering?
Yes, on request. Email hyd@szjunxian.com with the model number, or list your parameters and we will propose models that fit.
Do you supply the panel only, or a complete assembly?
Both, by default a bare module. We also bond touch panels and cover glass, fit custom FPCs and connectors, and supply a driver board where the design needs one.
What if none of the listed models fits?
About 120 new models a year start exactly this way: we modify a close model or build to your drawing. Send the size, resolution and interface you need.
Are you a manufacturer of smart serial uart lcd modules, or a trading company?
A manufacturer. Every model on this page is built on our own line in Bao'an, Shenzhen - we are a smart serial uart lcd module supplier in China with our own plant, 3 assembly lines and 52 staff, not an agent reselling another factory's panels. The business licence and ISO 9001 certificate with its registration number are published on our certifications page, and you are welcome to see the plant on video before you order.
Need a quote or a datasheet?
Send us size, resolution, interface and annual quantity. Our engineers reply within one working day. Sample MOQ 5 pcs, lead time 10-20 days.
