1,2,4,5,6,7 контакты надо соединить и подать на землю антенны?
я в схемотехники полный чайник, но этот чип очень нужен, подскажите чем отличается на схеме GND от AGNG и AGND? их все соединять ?
нет ли готового модуля с антенной, чтобы на выходе было 3 провода 3.3 вольта , TX NMEA и земля?
Александр,
Общий высокочастотной части 20, 22 RF GND
Общий цифровой части Power 6, 17 GND
Первые на землю антенны, вторые на массу питания.
Смотрите на вторую схему, первая для GL!
