5. Kev ceev faj txog kev siv
(1) Cov Khoom Siv Hluav Taws Xob: Siv lub taub hau 5V charger rau lub hwj huam mov, txuas nrog hom -C interface.
(2)Daim Ntawv Ceeb Toom Tshwj Xeeb Fais Fab: Yog tias siv lub txhab nyiaj fais fab rau kev muab khoom, lub load resistor yuav tsum tau txuas ua ke.
(3) Kev tiv thaiv lub cev: Kov nrog kev saib xyuas, zam kev cuam tshuam lossis kev quab yuam quab yuam.
(4)Kev Tiv Thaiv Ib puag ncig - ESD: Ua kev ceev faj tiv thaiv hluav taws xob hluav taws xob (ESD) kom tsis txhob muaj kev puas tsuaj.
(5)Environmental Requirements: Tiv thaiv cov dej noo thiab dej; tsis txhob muab lub cuab yeej tso rau hauv qhov chaw ntub dej lossis kua dej.
