Hardware
It has of 16 blocks of 5x8 LEDs, for a total of 80x8 LEDs. It is unknown if it's monochrome (just red) or two-color (red + green).
The electronics consist of two parts: a controller board and a LED board.
The LED board has the following ICs:
- SN74HC138: 3-to-8 line decoder/multiplexer
- SN74HC04: 6 inverters
- 10x SN74HC164: 8-bit parallel-out serial shift registers
The boards are connected through a 10 pin connector. There is also a 5V connector.
