USB breadboard Answered

Whats the best way of connecting a USB typeB pcb mount socket to a beadboard?


I'm wondering this too, I just got a 2x3" breadboard from radioshack and would like to power it from my usb port on my pc..

you need to be careful; without a software request, you can only draw 100 ma from usb without risking damage to your laptop.

Can you give me more information on this? How can I protect my port so I don't fry it? How can I get more power out of the USB port so I can power more things? I've got it setup right now and it works rather well, the USB is comming out of the port, down the wires & into the +/- of the breadboard, on the negative side I have a 100 ohm resister crossing over into the work area, then I have a a wire going from the positive power over to the work area. The LEDS light up but dim as I put more on of course. And how did you know I was using my laptop!... where is my tinfoil hat when I need it......

1) most usb systems are meant to charge or power mobile devices, such as thumb drives and mp3 players. the total current needed to run these things is very little. unrequested 9if you just plug wires in), you can get 100 ma. if your device, like an ipod or avr controller, requests the power, a usb port can supply 500 ma, or half an amp. to protect your port, a simple fuse should work. fuses blow mainly from too many amps. buy an inline modle rated for a low voltage, 100ma. if you start using devices like arduinos, swap the fuse for a 500ma modle. make sure to switch back later. you really cannot get more power. if you want 5 volts on the go, either use a 9 volts battery 7805 voltage regulator, or a 5 volt wall wart and a 7805 regulator. you should be able to draw about 1/1.5 amps that way, assuming you heatsink the v regulator. ____________________________________________________________ i knew it was a laptop because if you had a desktop, you would not need a bread board the powers off usb, but does not use usb data.

.. Can you solder some short pieces of wire to the socket, then bend the wires so they fit your breadboard?
