These are the latest pinouts most are using but the RY835AI shows multiple trigger grounds... should we be using or tying the grounds to ensure proper operation? There are many people posting of intermittent signal, long lock times, and other abnormalities.. are we hooking this up right!\r\n\r\nAlso, does the stratux code set the units internal settings for gps refresh rates>? The unit comes factory default at 1HZ but can be modified up to 18Hz.  How about baud rates and ports?  Some hook up via usb then connect to gpoi and that solves some issues.. so I am thinking this is a gps board settings issue.\r\n\r\nDoes the hardware store almanac and ephemeris   data for warm/hot and assisted startup or do we need to store that via software.  I assume some settings (port data/refresh rates/etc) are being retained in the unit via non vol memory while catalog and gps ephemeris are being held by the rechargeable onboard battery.  Anyone test how long that battery lasts?\r\n\r\nas for the gyros and other sensors.. see my other post.. I believe there are sever good open source code projects that will give us full AHRS and imu/inu functionality.\r\n\r\nPower:\r\nVDD -> PIN 02\r\nGND -> PIN 06\r\nAHARS Data:\r\nSDA1 -> PIN 03\r\nSCL1 -> PIN 05\r\nGPS Data:\r\nTXD -> PIN 10\r\nRXD -> PIN 08\r\n\r\nspec sheet here\r\nhttp://www.reyax.com/Module/GPS/RY835AI/RY835AI.pdf"},"comment":{"url":"https://api.github.com/repos/cyoung/stratux/issues/comments/166763429","html_url":"https://github.com/cyoung/stratux/issues/142#issuecomment-166763429","issue_url":"https://api.github.com/repos/cyoung/stratux/issues/142","id":166763429,"user":{"login":"ScraboTower","id":15007252,"avatar_url":"https://avatars.githubusercontent.com/u/15007252?v=3","gravatar_id":"","url":"https://api.github.com/users/ScraboTower","html_url":"https://github.com/ScraboTower","followers_url":"https://api.github.com/users/ScraboTower/followers","following_url":"https://api.github.com/users/ScraboTower/following{/other_user}","gists_url":"https://api.github.com/users/ScraboTower/gists{/gist_id}","starred_url":"https://api.github.com/users/ScraboTower/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/ScraboTower/subscriptions","organizations_url":"https://api.github.com/users/ScraboTower/orgs","repos_url":"https://api.github.com/users/ScraboTower/repos","events_url":"https://api.github.com/users/ScraboTower/events{/privacy}","received_events_url":"https://api.github.com/users/ScraboTower/received_events","type":"User","site_admin":false},"created_at":"2015-12-22T23:44:30Z","updated_at":"2015-12-22T23:44:30Z","body":"Dumb question, can you use USB just for GPS and GPIO for the AHRS ?
