The Y-Box is the contraption that will connect an Anelok acting as USB host with a (USB) power source and a USB device.
I made a first draft of the Y/Z stacking: http://downloads.qi-hardware.com/people/werner/anelok/tmp/ybox-stack.pdf This drawing is fairly crowded and is near the limit of what can be drawn in an understandable way with fped. The good things is that its' fully parametrized, so e.g., changing a tolerance will update everything that depends on it. The different types of lines are easier to tell apart when magnifying the page. All measurements are in mm. The two boxes in the middle are the receptacles for USB A and Micro USB B. The two small boxes under the USB A connector are its "legs" that go through the PCB. The thin border at 0.8 mm from the USB A connector is the "mouth" of the connector. The PCB is drawn with a slightly thinner line than the connectors. On the outside, we have the top and bottom case shell. I didn't draw openings, but they're relatively straightforward. It should be pretty easy to generate a 2.5D model from this. Next, the circuit. Schematics: http://downloads.qi-hardware.com/people/werner/anelok/tmp/ybox-stack.pdf The diode D2 makes sure the LED isn't lit when connecting Analok and power source to the wrong ports. The layout: http://downloads.qi-hardware.com/people/werner/anelok/tmp/ybox-20131025.png This is completely untested. I'll need to build it when getting to USB host mode, but that'll still take a while. The information most important for now is the thickness of the case parts. I'll need that to buy acrylic blocks of the right size for making the various cases. - Werner _______________________________________________ Qi Hardware Discussion List Mail to list (members only): [email protected] Subscribe or Unsubscribe: http://lists.en.qi-hardware.com/mailman/listinfo/discussion
