The Transparent Acrylic Case for Arduino UNO R3 is a simple, well-designed enclosure that protects your Arduino UNO board while keeping it fully accessible and visible. If you’re running a project on a desk, in a demonstration setup, or inside a cabinet, leaving the UNO board exposed is a risk — accidental shorts from loose wires, dust settling on the headers, or physical contact can cause unexpected failures. This case prevents all of that without getting in the way of your work.
The enclosure is built from six acrylic panels — top, bottom, and four sides — held together with copper pillar standoffs, M2.5 and M3 hex screws, and matching nuts, all included in the package. Assembly is straightforward and requires no special tools. The copper pillars raise the board off the base panel, providing adequate air circulation underneath.
What sets this case apart from generic enclosures is the precision of its cutouts. The USB port, DC power jack, ICSP programming header, and all digital and analog I/O pins remain fully accessible through the case walls. You can program the board, connect shields through the top, and power it without ever removing the board from the enclosure.
The full transparency of the acrylic also means your onboard LEDs — power indicator and pin 13 — are visible at all times, which is useful during debugging and demonstrations. Robotics developers, and hobbyists building arduino projects that need a finished, presentable look without the cost of a custom enclosure will find this a practical choice. StemVolt includes all mounting hardware so the case is ready to assemble right out of the box.
