In life, every so often one hears of a concept that is so simple and so elegant that the fact that one had not heard of it before today makes one’s jaw drop in disbelief:
> Reversible USB-A. Well this maybe wasn't the most critical feature anyone expected, but, consequence of our new PCB & case combined construction, it was easy to make USB-A reversible. So why not!
- mNovak 6y agoI'm more impressed by the cavity PCB construction--fill with epoxy and boom dead simple waterproofing! I've never encountered this before; wonder if it's available with the batch fabs.
- SecurityLagoon 6y agoPretty common in ruggedized devices. Has the benefit of keeping components stuck down under vibration and tamper evident too.
- jononor 6y agoThe technique is called "potting", and is common for small rugged devices. I think nearly all assembly houses will offer it. Some electronics components, such as relays, power converter modules also use it.
- mastax 6y agoThe difficult part is the step milling for the cavity. Its unusual so you need to work with the fab to get it right. Bunny Huang had a good post about it.
- JunkDNA 6y agoUSB remains the only connector I use where I routinely get the orientation wrong 3 times.
- sowbug 6y agoThis is a good discussion of how it works: https://electronics.stackexchange.com/questions/209941/two-sided-connectorless-usb-on-a-pcb https://electronics.stackexchange.com/questions/209941/two-s...
