Arduino Uno R4 WiFi case with LED matrix window
A protective box for the Arduino Uno R4 WiFi that keeps the 12 x 8 LED matrix visible. The board is 68.6 x 53.3 mm and uses the classic Uno hole pattern, so the base carries four 3 mm standoffs at those positions and a 2 mm floor. The lid has a 30 x 22 mm window over the matrix, a slot for the USB-C connector, a hole for the barrel jack and long openings above both header rows so jumper wires still plug in. Walls are 2 mm, corners have a 3 mm radius, and the lid holds on with four M3 screws into printed bosses. The whole assembly prints flat in two parts with no supports.
A generated case can be made exactly as tall as the shield stack you run, which a shared download cannot know. In SpeakCAD you describe the box, preview it free in the browser, raise the walls or add a Qwiic cable exit in the chat, and download the STL.
