Other stuff
- SMD291 - FLUX farnell 1850216, digikey, or 5cc
Todo/tocheck
- make papilio output +/- 71MHz differential signal, at several differential voltages.
- add footprints to eagle
- can spartan-differential easily be made compatible with rs484?
Other Documents
- Spartan-6 FPGA PCB Design and Pin Planning Guide
- Sending serial data over 2 papilios -- looks interesting http://www.programmableplanet.com
