You could build your own manually using a prototype cape and a few through-hole buffer chips. It sucks soldering 8-9 boards up by hand with "flying wires", but it shouldn't take more than a few hours if you're decent with a soldering iron and have the right tools (a good set of diagonal cutting pliers and a nice wire stripper). -- Charles Steinkuehler [email protected] -- website: http://www.machinekit.io blog: http://blog.machinekit.io github: https://github.com/machinekit --- You received this message because you are subscribed to the Google Groups "Machinekit" group.
