TCC70A Media Playback and LED Control Board
The NovaStar TCC70A is an integrated multimedia player for compact LED signs. It combines sending and receiving functions and provides eight HUB75E connectors, supporting up to 16 groups of parallel RGB data. Typical uses include community displays, lamp-post screens, small traffic displays and vehicle-mounted signs.
A PC, mobile phone or tablet can publish programs and control the screen. Ethernet and the built-in Wi-Fi AP provide local connection options, while cloud publishing and monitoring platforms support screen management across locations.

Choosing the Connection Method
Use the Wi-Fi AP to connect a nearby user terminal, Ethernet for network or control-PC access, or a FAT32 USB drive for media playback. RS485 supports a compatible sensor, such as a light sensor, or a functional module.
For an installation requiring documented 4G and GPS functions, compare the TCC70G. Those functions are listed in its specification; they are not listed for the TCC70A in the document below. Confirm module compatibility and the screen layout before selecting either board.
Frequently Asked Questions
Is TCC70A a sending card or a receiving card?
It integrates both sending and receiving capabilities with multimedia playback. Its eight HUB75E connectors connect to the LED screen, with support for up to 16 parallel RGB data groups.
Can I control TCC70A from a tablet?
Yes. The specification supports program publishing and screen control from a PC, mobile phone or tablet. The built-in Wi-Fi AP allows a user terminal to connect locally.
Does TCC70A include 4G and GPS?
The linked TCC70A specification lists Ethernet and Wi-Fi AP control, but does not list 4G or GPS functions. The related TCC70G specification explicitly includes 4G, GPS positioning and GPS time synchronization.
What USB file system does TCC70A require?
FAT32 is the only supported USB file system in the specification. The maximum size of a single file is 4 GB, and the available internal storage is also listed as 4 GB.
Can I combine the maximum width and height into a 1280 × 512 screen?
No such loading configuration is specified. The maximum load is listed as 512 × 384, while 1280 × 128 and 384 × 512 are separate width and height examples.
