Shouldn't be too expensive. Probably cheaper than the original Robostix from gumstix. We are waiting for the Quote on PCB's so will know for sure then. -----Original Message----- From: Andrii Nakryiko [mailto:and...@gm...] Sent: Friday, July 30, 2010 9:31 PM To: General mailing list for gumstix users.
