Posted in Arduino Hacks, Parts Tagged Arduino Uno, connector, port, retrofit, usb Post exactly… But the latest-and-greatest USB interface can be a bit fiddly, especially with DIY gadgets, so we can’t blame him for going with the more reliable approach. Of course you could go all the way and retrofit the Uno with a USB-C port, as we’ve seen done with devices in the past. To be safe, he says anyone looking to use his trick with their own designs should order more boards than they think they’ll actually need. But while they may not be terribly attractive, most of them were serviceable. Some of the holes got pretty tore up as the bit routed out the edges of the board, with a few of them so bad mentions there might not be enough of the pad left to actually use. Under a microscope, you can see the downside of this approach. Looking to avoid the premium he’d pay to have the board house do castellated holes, he cheated the system a bit by having the board outline go right through the center of the standard pads.

The design is straightforward, but as explains in the video below, there’s actually more going on here than you might think.

Naturally there are no components on the PCB, it simply adapts the original through-hole footprint to the tight grouping of surface mount pads necessary to mount a female micro USB port. Looking to at least move things in the right direction, recently set out to create a simple board that would let him mount a micro USB connector in place of the Uno’s original Type-B. It wouldn’t be a stretch to say that many Hackaday readers only keep one of these cables around because they’ve still got an Uno or two they need to plug in occasionally. Even with more and more devices making the leap to USB-C, the Arduino Uno still proudly sports a comparatively ancient Type-B port.
