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

This model is for the [Arduino NANO V3].

Here’s the official pinout diagram:

Features:

• Perfectly matches the official schematic
• Clearly shows the function of each pin
• Comes with a base for stable desktop placement
• Includes an adapter part that allows you to swap in a real 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 coding for pins within the same series to facilitate quick identification
  • Material selection: Tri-color PLA
