We should use a standoff device with a symbol and a package from the eagle libraries. If we use a standardized device from the eagle library we can insure that the proper keepout and restrict elements are present, tested, and consistent.\r\n\r\n(2) In the SCH the symbol for the cable connector uses a GND flag instead of a GND symbol on the GND net.\r\n\r\n(3) USB connector currently has the wrong prefix in the Name field\r\n\r\n(4) Level shifting IC currently has the wrong prefix in the Name field\r\n\r\n(5) USB needs Tnames and Tvalues elements in the SCH\r\n\r\n(6) 3.3V and 5V output traces from the vregs both have 20mil vias that are not masked on top or bottom. For testing purposes I only need the bottoms of the vias unmasked. Unless there is reasoning, I think the tops of these vias should be masked.\r\n\r\n(7) VCC trace has two 20mil vias  that are not masked on top and bottom. I only need one of these vias unmasked on the bottom for testing (either one works for me), and unless there is reasoning, I think the tops of these vias should be masked.\r\n\r\n(8) There are two GND vias that are unmasked on the top and the bottom. One is above the 1x5 header and one is to the left of the 2X5 connector. I think that both of these need mask on top and bottom unless there is a reason.\r\n\r\n(9) R1, R5, R8 and all of the resistor arrays need some sort of silk in the package.\r\n\r\n(10) Logic shifting IC needs a tPlace polarity marker that is outside of the package.\r\n"},"comment":{"url":"https://api.github.com/repos/sparkfun/Bus_Pirate/issues/comments/145582540","html_url":"https://github.com/sparkfun/Bus_Pirate/issues/1#issuecomment-145582540","issue_url":"https://api.github.com/repos/sparkfun/Bus_Pirate/issues/1","id":145582540,"user":{"login":"ericorosel","id":3160317,"avatar_url":"https://avatars.githubusercontent.com/u/3160317?v=3","gravatar_id":"","url":"https://api.github.com/users/ericorosel","html_url":"https://github.com/ericorosel","followers_url":"https://api.github.com/users/ericorosel/followers","following_url":"https://api.github.com/users/ericorosel/following{/other_user}","gists_url":"https://api.github.com/users/ericorosel/gists{/gist_id}","starred_url":"https://api.github.com/users/ericorosel/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/ericorosel/subscriptions","organizations_url":"https://api.github.com/users/ericorosel/orgs","repos_url":"https://api.github.com/users/ericorosel/repos","events_url":"https://api.github.com/users/ericorosel/events{/privacy}","received_events_url":"https://api.github.com/users/ericorosel/received_events","type":"User","site_admin":false},"created_at":"2015-10-05T16:02:32Z","updated_at":"2015-10-05T16:02:32Z","body":"Sorry it's been so long on this, I unsubscribe to repos so I never receive any notifications from activity on them.\r\n\r\n(1) if the design is using a standard footprint 'DP6037' I think there needs to be a symbol for the footprint within schematic, or the standoffs need a symbol. \r\n\r\n(2) Thanks\r\n\r\n(3) We've (QC) been using the engineering 'eagle rules' wiki for reference on prefixes. I agree with you that JP is not the appropriate prefix per the industry standard, but according the the Engineering Wiki, it is what we use for connectors. Maybe there is en explanation from someone in engineering as to why we have a different set of prefixes than the industry standard. \r\n\r\n(4) Thanks\r\n\r\n(5) Thanks\r\n\r\n(6) I see what you are talking about. I'm not entirely sure why we have the limit set to 20 mil. My only thought being that perhaps the drill is large enough that the mask would cover the metal on the top and the bottom of the via, but there would still be a hole that is not really masked closed? Or maybe it's something specific to GP? Having the vias unmasked on the top isn't the end of the world, but I would generally like to stay away from exposing metal unnecessarily, especially when it's metal on PWR or GND lines. Honestly, I think we could order protos with the tStop present, but I would like to get an explanation from engineering about why the 'limit' in the DRC is set to 20 mil.\r\n\r\n(7) and (8) same as '(6)'\r\n\r\n(9) thanks\r\n\r\n(10) thanks"}}
