NEW MICRO YARH.IO DESIGNED FOR SKILLED OPERATORS

A few months back we brought you word of the YARH.IO, an extremely impressive Raspberry Pi portable that featured rugged good looks and a unique convertible design made possible by a removable keyboard. One of the most appealing aspects of the design was that everything was built from off-the-shelf modules; it only took a couple jumper wires and some scrap perfboard to get everything wired up inside the 3D printed enclosure.

The downside of this construction style was that the finished product was a bit chunkier than was strictly necessary. But that’s not the case with the new YARH.IO Micro. The palm-sized portable looks almost exactly like the original, though it had to ditch the removable keyboard in the shrinking process. Gone as well is the touch pad, though with the touch screen capabilities of the Pimoroni Hyper Pixel four inch IPS display, that’s not much of a problem.

What’s the catch? Well, at a glance we can tell you this one is considerably harder to build. For one thing, you’ll need to remove the Ethernet and USB connectors from the Pi 3B+. The USB ports get relocated, but Ethernet understandably has to be left on the cutting room floor. Nothing to worry about with the GPIO pins, the display takes up all of those, but you’ll probably want to wire the I2C lines to the female header on the side of the case so you can add external hardware and sensors.

You also need to nestle an Arduino Pro Micro in there to communicate status information about the battery to the operating system over I2C. If you wanted to save a little wiring you could probably leave off the DS3231 RTC module, but it depends on how often you’ll be able to sync up with NTP.

While it may be more difficult to assemble than its predecessor, it’s certainly not unapproachable. Once again, no custom PCBs or exotic components are required. You might be doing a lot more soldering (and desoldering) than you would have before, but it’s nothing that the average Hackaday reader isn’t capable of. For your troubles, you’ll get a exceptionally portable Linux machine that’s ripe for hacking and modification.

If the time and effort it will take to put together a YARH.IO is a bit more than you’re willing to invest right now, there’s always commercial alternatives like the DevTerm. But whether you go with the original or this new Micro edition, we think the satisfaction of having built the whole thing yourself will be more than worth it.
