The Colorlight Card is a board specifically designed to run panels. Unlike FPP using a Beaglebone Black with an Octoscrolla or a Raspberry Pi with a Pi hat, the Colorlight Card has dedicated, purpose-built hardware to manage many different panel configurations. To get data to the Colorlight Card, you can utilize a dedicated sending interface or FPP . Either way, any connection being made to the Colorlight Card must be Gigabit. The Raspberry Pi 3 B+ is a great way to get your panel data directly to the Colorlight card without having switching hardware in-between.
The Colorlight Card needs to be configured to work correctly. Please visit the following page to download the latest version of the LEDVISION software. As of 1/21/2021, the current recommended version is listed as 7.0. https://www.lednets.com/Products/Software/37_31.html
