WARP FPGA Board I/O
10/100 Ethernet
Intel LXT972A physical layer Ethernet transceiver
Three status LEDs. LEDs only work after the PHY is initialized by a MAC in the FPGA.

RS-232 UART
FPGA board configured just like a PC- male DB9 connector, Tx on 3, Rx on 2, GND on 5. Null-modem (crossover) female-female cable required to connect to PC's serial port.
Digital I/O
16-bits of unbuffered 3.3v I/O connected directly to FPGA I/O pins. 4 ground pins at each corner of 20-pin 0.1" header.
