Nano Expansion Shield with Screw Terminals - IO Adapter for Nano

Specifications

• Compatibility: Arduino Nano V3.0, Nano Every, and other Nano-footprint boards.

• Terminal Type: High-quality 3.5mm pitch screw terminal blocks.

• Pin Breakout: All 30 pins are broken out (D0-D13, A0-A7, VCC, GND, RST, 5V, 3V3).

• Markings: Clear, high-contrast silk-screen printing for easy pin identification.

• PCB Material: High-grade FR-4 glass fibre with tinned solder pads.

• Mounting: Two pre-drilled mounting holes for secure enclosure installation.

• Dimensions: Approx. 53mm x 36mm.

Key Applications & Projects

• Permanent Home Automation: Securely wire up relays and sensors behind switchboards.

• Industrial Control Panels: Mount an Arduino Nano inside a control box where vibration is a factor.

• Educational Training Kits: Prevent students from accidentally unplugging wires during experiments.

• Custom MIDI Controllers: Use the screw terminals for long-lasting connections to knobs and sliders.

Project Evolution

• Past Projects (Prerequisites): If you’ve mastered basic "Blink" and sensor logging on a breadboard, you’re ready for this.

• Feature Upgrade: This shield unlocks Vibration Resistance. While a breadboard is great for testing, this shield allows your project to be portable and rugged. It transforms the Nano from a "learning tool" into a "field-ready controller."

• Effort/Requirements: Beginner. No soldering is required on the shield itself. Just plug in your Nano and use a small flat-head screwdriver to secure your wires.

Virtual Technician & Wiring

⚠️ Tech Tip: Always strip your wires by about 5mm and twist the strands before inserting them into the terminal blocks. Do not over-tighten the screws to avoid stripping the threads.

Package Includes: 1 x Nano Expansion Shield with Screw Terminals

Frequently Asked Questions (FAQ)

• Is soldering required for this shield? No, the shield comes fully assembled. You just need to plug in your Nano.
• Does it support the Arduino Nano Every? Yes, it is compatible with any board that follows the standard Nano pinout.
• Can I mount this inside a DIN rail box? Yes, with a suitable 3D-printed or universal DIN rail adapter.
• What size screwdriver do I need? A standard 2.0mm or 2.5mm flat-head precision screwdriver.
• Are the pins labeled on the board? Yes, every terminal is clearly labeled on the silk-screen.
• Can I use this for high-current applications? No, it is designed for signal-level and low-power control (Max 1A per trace).
• Does the shield have a power LED? No, it relies on the power LED of the mounted Nano board.
• Is the Nano board included? No, this is the expansion shield only.
• Can I still use the USB port on the Nano? Yes, the USB port remains fully accessible.
• Does it work with the older Nano V2.0? Yes, the physical footprint is the same.
• How do I mount the board to a surface? Use M3 screws through the two mounting holes provided.
• Can I use solid core wire with these terminals? Yes, both solid core and stranded wires work perfectly.
• Is there a reset button on the shield? No, you use the reset button on the Nano itself.
• What happens if I plug the Nano in backwards? Do not do this; always ensure the USB port aligns with the marking on the board to avoid damage.
• Can I stack other shields on top? No, this is a terminal breakout, not a stackable header shield.
• Is it compatible with 3.3V logic? The shield is passive, so it works with whatever voltage your Nano uses.
• What is the pitch of the screw terminals? 3.5mm.
• Can I use this for RS485 wiring? Yes, it's perfect for securing the TX/RX and GND wires for serial communication.
• Does the shield have built-in resistors? No, it is a direct 1-to-1 pin breakout.
• Is the PCB double-sided? Yes, it uses a high-quality double-sided FR4 PCB for durability.
