Hi Dr Patel,

In about 4-8 weeks I will have about 10-25 of our revised stamp expansion
board.
It features 80 digital outputs, each group of 8 controlled by an SX18.
Currently we discuss the best implementation for the communication between a
stamp
and these SX18. Take a look at http://www.boselectro.nl/synop.html
You find the discussion group at http://groups.yahoo.com/group/synop
If you can wait a few weeks and/or if you are interested, please join.
These board will go for about US$ 30. At this time I can only offer empty
pcb's.
Full schematics and part lists will be provided.
If you are interested send a note to info@b... keyword synop

Greetings peter
