A used old Arduino UNO R3 board with some scuffs and dings. A popular open-source microcontroller board. It is an accurate representation of the physical board, including all of the connectors, components, and markings. The model can be used to study the board and its layout, or to create virtual prototypes and simulations.

This 3D model of an Arduino Uno board is a detailed, accurate representation of the original Arduino Uno circuit board. The model consists of several components, each one faithfully recreated in 3D. Starting with the main board itself, it is the same shape and size as the original Arduino Uno board, measuring in at 68mm x 53mm. On the top side of the board, there are two rows of female pins which can be used to connect additional components or boards. On the bottom side, there are two sets of male pins which plug into a standard breadboard for easy wiring and prototyping. In between these pins is a microcontroller chip with 14 digital input/output ports and 6 analog inputs. Also present on the board are a USB port for programming, a power jack for supplying power to the board, a reset button and LED indicator lights. All these components are accurately recreated in 3D and can be rotated, zoomed in on or otherwise manipulated to get a better view of any part of this model.
