yea, when i saw this is the newsletter yesterday (from thinkgeek that is) i imediately wondered how good it would be for a batch of FPGA's.

course with that many cables ya'd need some sort of ducting just to handle then all and keep them untangled...

The power adapter is only 5V @ 4A. That's only ~20Watts. How much power from your typical FPGA is taken from the USB port itself?

Tips? 1crazy8pMqgwJ7tX7ZPZmyPwFbc6xZKM9

to my knowledge, none. they have seperate power usually, since they each need about 20watts. i'm going off what i've seen/read here though.

It looks like a switch..... I doubt all USB ports can be used at one time.

until we know the actual power draw the jalepeno's need from the usb port, it's a guess. but since that is a power hub, it should suffice. again, guessing though.

beware tho, many USB hubs are infact daisychain internally.... and some USB controllers dont like that.

Yeah, I'm guessing (hoping?) that they had the foresight to build in a connector for external power.

It looks like 4A extra.

Tired of substandard power distribution in your ASIC setup???   Chris' Custom Cablez will get you sorted out right!  No job too hard so PM me for a quote
