Power Supply (SMPS) Recommendation
Each module needs approximately 10 A at 5V. Choose your 5V Slim Body SMPS based on how many modules you are running:
| Number of Modules | Recommended SMPS |
|---|---|
| 1 module | 5V 10A slim |
| Up to 5 modules | 5V 40A slim |
| Up to 8 modules | 5V 60A slim |
| More than 8 modules | Use multiple SMPS units |

Frequently Asked Questions
Which controllers does this module work with?
It works with HUIDU full-colour controllers — D16, C16L, A3L, A4L, A6L and higher versions. It does not work with WF1, WF2, WF4, or DIY ESP8266 / ESP32-based controllers.
Which power supply (SMPS) should I use?
Each module needs about 10 A at 5V. Use a 5V 10A slim for a single module, a 40A slim for up to 5 modules, and a 60A slim for up to 8 modules. For more than 8 modules, use multiple SMPS units.
Does the module include cables?
Yes — a power cable and an FRC (flat ribbon cable) are included free with each module.
What is the difference between P3.0 and P4 / P5 / P10?
The number is the pixel pitch (distance between LEDs). P3 has a 3 mm pitch — the sharpest, for close-range viewing. P10 has a 10 mm pitch — for viewing from further away. The smaller the number, the higher the resolution.
Is it safe for outdoor use?
No — this is strictly an indoor module. For outdoor use, choose the P4 Outdoor or P6 Outdoor module.
Will it flicker on camera?
No. The 3840 Hz refresh rate keeps the image flicker-free, even in camera and video recordings.
How large a screen can I build?
Each module is 64×64 pixels. Connect multiple modules to build a larger screen — the more modules, the larger the display.
