One of the newer features on the Raspberry Pi B+ and Raspberry Pi 2 Model B is improved power management.<\/p>\n<p>By default, the 4 USB ports on the Raspberry Pi Model B+ and Raspberry Pi 2 only have 600mA available to them, that\u2019s 600mA SHARED! That all very well if you only intend on plugging a wifi dongle, keyboard and mouse in. But what if you want to plug in something a little more power hungry?<\/p>\n<p>BOOST THE CURRENT!<\/p>\n<p>To do this, you can simply edit the \/boot\/config.txt file<\/p>\n<div class=\"codecolorer-container text default\" style=\"overflow:auto;white-space:nowrap;\"><div class=\"text codecolorer\">sudo nano \/boot\/config.txt<\/div><\/div>\n<p>Then add this simple line of code:<\/p>\n<div class=\"codecolorer-container text default\" style=\"overflow:auto;white-space:nowrap;\"><div class=\"text codecolorer\">max_usb_current=1<\/div><\/div>\n<p>Don&#8217;t forget to save the config file and reboot your Pi.<\/p>\n<p>What this does is doubles the available current to the Raspberry Pi USB ports. That now gives you 1.2A (1200mA) of juice total! <\/p>\n<p>I should point out that you will need a decent 2A power supply!<\/p>\n<p>If you\u2019d like to know a bit more about what\u2019s actually happening when you set max_usb_current to 1 then head over to this post on the Raspberry Pi Forums.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>So you&#8217;ve got a Raspberry Pi, but the USB output current isn&#8217;t driving what you need it too?
