前回ワンコの毛がファンに絡まり電圧低下を引き起こした<\/a>のではないかということで，ワンコのいるリビングにはRaspberry Pi 3 Model B (RPi3)に代えてファンレスのケースに入っている同B+ (RPi3+)を置いています．電源は前回電圧低下の警告が出たときと同じものを使っています．<\/p>\n\n\n\n

この電源はUSB電源アダプターで，5V 3Aをうたっています．RPi3もRPi3+も必要な電源は5V 2.5Aなのでどちらでも十分なはずです．<\/p>\n\n\n

\"\"<\/figure>\n<\/div>\n\n\n

しかし，あいかわらず電圧低下の警告が出ます．これはその5V 3Aの電源が不良としか考えられません．<\/p>\n\n\n\n

5V 2.5A以上の電源の予備はないので困っています．<\/p>\n","protected":false},"excerpt":{"rendered":"
