NovaStar JT20 for Connected Traffic Signage
The JT20 combines media playback, sending and receiving functions on one board. It is intended for compact LED information displays in city signage, expressways, parking and queuing systems. A PC or supported client platform can publish content, control screens and monitor groups of displays remotely.
For a networked installation, check the cellular region first. The original linked NovaStar JT20 Specifications V1.0.2, dated June 14, 2023, says a 4G module is supplied and that its stated 4G access is limited to China. This is not a guarantee of compatibility with overseas mobile networks.

Planning an Installation
Match the HUB75E pinout and cabinet configuration before connecting display modules. The stated maximum width and height describe separate layouts; they cannot be combined into a 1280 × 512 load. Likewise, decoding a 1080p media file does not make the board capable of driving a full 1080p LED screen.
For local updates, use a supported USB drive or connect a terminal to the built-in Wi-Fi access point. RS485 can connect a compatible brightness sensor or other supported module. GPS support is documented, but the supplied packing list does not establish that a GPS antenna is included.
The relay’s switching rating is separate from the board’s power input. The specification advises against directly switching AC through the player relay and provides a recommended circuit arrangement for that use. Use the manufacturer’s structural drawings when designing mounting holes; the outline diagram is not a fabrication template.
Frequently Asked Questions
Is a 4G module included with the NovaStar JT20?
The linked V1.0.2 specification says the JT20 ships with a 4G module. It also limits the documented 4G network access to China, so confirm module and carrier compatibility for the installation region.
Does JT20 support GPS?
Yes. The specification lists GPS support and a GPS antenna connector. Check the required antenna and supplied accessories separately; the packing list does not establish that a GPS antenna is included.
Can JT20 drive a 1280 × 512 LED screen?
No such configuration is established by the specification. It lists up to 512 × 384 pixels, with separate examples of 1280 × 128 for maximum width and 384 × 512 for maximum height.
How much storage is available for media?
The JT20 has 8 GB internal storage, of which 4 GB is listed as available. It also supports USB playback with FAT32 and a maximum file size of 4 GB.
What power supply does JT20 require?
The input range is 4.5–5.5 V DC and maximum power consumption is 10 W. Do not confuse this supply range with the separate 30 V DC, 3 A relay switching rating.
