给M7要增加音量键和蓝牙的机友作参考(M7 拆机图) 给M7要增加音量键和蓝牙的机友作参考(M7++拆机图) 海纳的M7系列是目前采用三星PV210芯片组中较为成熟的机子，因系列中型号较多，较早的M7，不带音量键、不带蓝牙，为便于机友的改装，特意拆了我的M7++，将相关的接线予以公示，给机友们作改装时的参考。 先借机一起来看看拆机后的内部图。 首先是全貌图(见下图) 主芯片三星PV210(见下图) 电池5.5mm*49mm*78mm 2300MAH 共两块(见下图) are equipped with tools, small parts, supplies, transportation of small quantities of materials, materials testing and business contacts.
