The Cluster Base Board connects four Series 2 FPGA Boards to a small cluster node.
- 10 bit bus connected to all FPGA Boards and the external I/O connectors
- 44 bit open ring network for board to board communication. First and last FPGA Board are connected to an external I/O connector.
- Two 2x32 pin headers for external I/O. Each one contains:
- 10 bit bus signals
- 44 GPIO's connected to first or last FPGA Board
- Power supply pins
