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 ..
