For price that is cheaper: https://www.digikey.com/products/en?lang=en&site=us&KeyWords=A118476-ND With pin's that are smaller then Amphenol's 0.2x0.5(TE Connectivity) vs: 0.2x0.6(Amphenol) Regards, -- Robert Nelson https://rcn-ee.com/ -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
