Sysolution K21 Asynchronous Cascading LED Sending Card
$ 251.28
The Sysolution K21 is an asynchronous cascading LED sending card with hardware video decoding, 500 MB flash and Ethernet, serial and USB communication. Its original resolution descriptions conflict, so confirm the specific version and screen load before ordering.
K21 cascading control for matching LED screens
The Sysolution K21 supports stored media, text, clocks and scheduled content for full-color LED displays. Its listed cascading function can show the same content across screens of the same size. HCP4 file readback and PC-based configuration support setup and maintenance of the receiving-card system.
Resolution needs confirmation: The original feature text says a fixed 640 × 256 resolution, but its parameter table says 1200 × 256. This discrepancy has not been resolved by a matching specification. Check the exact controller version before sizing a display. The scan, memory and communication details below retain the original listing’s values without borrowing specifications from other K-series cards.

Frequently asked questions
Is the K21 resolution 640 × 256 or 1200 × 256?
The original product information contains both values: the feature list gives fixed 640 × 256, while the parameter table gives 1200 × 256. Confirm the hardware/firmware version and required screen layout before ordering; neither value is treated here as a verified universal maximum.
Can one K21 show the same content on several screens?
The listed cascading feature supports more than one screen when each screen has the same size, displaying the same content at the same time. Confirm the receiving-card and HUB arrangement for the installation.
Which scan types and drivers does the K21 support?
The original specification lists scan types from 1 through 16 and PWM-driver support including MBI5041. Match the actual module driver, scan type and HUB wiring before configuration.
Does K21 include audio and mobile-network support?
An onboard WCDMA/GPRS 3G modem is listed, while audio uses an optional USB sound card. Confirm the fitted modem and local network availability; do not assume 4G or built-in audio output from this information.
Which software and media can I use?
LEDEditor V10 and LEDSet 2.0 are listed. The card supports the video, animation, image and text formats in the parameter table, as well as HCP4 file readback, scheduling and USB storage expansion.
