USB-PWR: 4xUSB switchable power breakout (6HP)
2 in stock.
IMPORTANT: This module is a power breakout only - there is no provision for data passthrough.
It seems that USB breakouts are a Thing nowadays, and I won't deny that I've found it an extremely useful addition to my setup given all the USB-powered odds and sods that I have lying around (a USB lamp, in particular!)
Each output is switchable, with a power LED, and there are inline fuses on the USB power rails - for these builds I have used 100mA fuses, which is sufficient for my own needs and won't overburden my case supply should I have four power-hungry peripherals attached. The fuses are replaceable if you can wield a soldering iron and are confident with SMD components - you can replace them with a larger (or smaller) value fuse or simply add a zero-ohm link or 22R resistor should you feel so inclined.
Remember, THIS IS A POWER BREAKOUT ONLY - the data lines are terminated with a 200ohm resistor, which may upset some 'smart' chargers. You can work your way around this should you wish, but if something goes TITSUP (Total Inability To Supply USB Power) then you're on your own.
Basically, if it runs off dumb USB power then you should be OK running it from this. It's not possible for me to test every USB device out there, so a bit of common sense is essential too.
Because of the way the data lines are terminated, the functionality is equivalent to that of a 'dumb' charger - some recent devices which are altogether too clever for their own good (hello Apple, hello Samsung) may not work. On the other hand, it'll quite happily power various microcontroller-based devices and my Android tablet, so ....
Finally, powering this module does not require a 5V rail - power is taken from the 12V rail and regulated down to 5V; this was a conscious design choice on my part, since the 12V rails on a power supply will be rated to a higher current than the 5V rail (assuming that you actually have a 5V rail, that is)
Supplied with a 6HP panel fabbed from FR4 fibreglass with a matt grey finish and gold ENIG lettering. A power cable and mounting hardware is also supplied.
