A Tiny USB Hub For All Your Hardware Modding Needs

Going all of the means Mod to the heady days of Eee PC modding, {hardware} hackers were at the hunt for small USB hubs that may simply be liberated from their enclosures and built-in into no matter undertaking they occur to be operating on. From time to time you notice suggestions in the market for makes and fashions which lend themselves to this type of repurposing, but it surely’s appeared tougher than essential to supply the sort of elementary element.

Which is why [RETROCUTION] has evolved a USB hub that’s no longer most effective extraordinarily small, however quite simple to collect with most effective six elements. Plus perfect of all, they’re filth affordable.

When you upload up the price of getting the PCBs made and purchasing all of the SMD elements, the per-unit worth of those hubs is most effective going to be a couple of bucks. If you’ve were given what it takes to make the PCBs in-house, even higher. Considering how a lot more uncomplicated this stuff may just make different tasks, it kind of feels greater than definitely worth the in advance value.

The celebrity of the display is the FE1.1s, a four port USB 2.0 controller in a SSOP-28 bundle. As of this writing, it is going for roughly 25 cents from the standard in another country assets (even much less, for better orders). Add to the combo a couple of 10 μF ceramic capacitors, a 2.7 kΩ resistor, and a 12 MHz crystal.

There’s no provision for precise USB ports within the design, however they might simply soak up house anyway; this hub is meant to be without delay soldered to the opposite units. Incidentally, to cut back the selection of strains and pads at the PCB, there aren’t energy traces for the downstream units both. So you’ll wish to energy them one at a time.

The passives are 0603, however the crystal is a superb old skool through-hole element. [RETROCUTION] assembles the forums with a solder paste stencil and a sizzling air station, however in case you’ve were given a bit follow, it’s indubitably one thing you’ll want to do with an iron. With the sort of easy design, you’ll want to construct an entire life provide of those itty-bitty hubs in a day. That’s indubitably our plan, anyway.
