Reversing status:

• Fully reverse engineered!

Main features:

• Module for Infinity Series B displays.
• Power supply is 24V DC.
• Driven by EP2C5T144C8 @ ~25mhz
• 6 MBI5026GD display drivers for low side
• 12 dual mosfets for high side
• 2 rj45 jacks for array control, using rs-485 protocol.
• Very much like the design for the 72x24 model, trades a Cyclone II and something is different about the mosfets, also pushes the resistors away from the drivers and closer to the LEDs.
