RE: Warning about cheap leads
I did a little test today, to see what amperage the RPi needs.
Below are my results. What you should gain with this, is the importance of a good power supply - 1 amp at least and a powered hub, especially if you have more than a coupe of USB devices. The devices were attached and the system rebooted. The devices are cumulative. At rest (Red light on) = 0.11ma Figures in ma. Devices attached -> Peak amperage -> At rest amperage Nothing - 410 - 330 Wireless KB - 430 - 350 Ethernet - 510 - 450 Hub no power - 620 - 540 Hub powered - 510 - 460 Wifi – no hub - 600 - 510 Wifi – hub no power - 760 - 650 Wifi – hub powered - 510 - 460 USB speakers no power - 750 - 650 UBS speakers powered - 520 - 460 Pwd HDD no power hub - 520 - 460 Flash drive unpowered hub - 890 - 810 Please read before you post How to post a log file If you liked my help, click on "Thanks" to show your appreciation.
