This is a pinout model specifically designed for the ELEGOO microcontroller series, making it easier to visualize the function of each pin when working with these MCUs.

This model is for the [Arduino NANO V3].

First, here’s an official pinout diagram:

Features:

• Fully compatible with the official schematic
• Clearly shows the function assigned to each pin
• Includes a base that allows it to stand upright on a desk
• Comes with an adapter part, enabling you to replace it with an actual NANO V3 (see the last image)
• Non-printed bill of materials:

  • 4mm × 2mm round magnets: 6 pieces
• Color scheme reference:Important! Since this is a series of four models, we recommend using the same color for pin labels within the same series to facilitate quick identification
  • Material choice: Tri‑Green PLA
