NOYITO Proto Screw Shield Assembled Terminal Point Prototype Expansion Board User Manual

1. はじめに

The NOYITO Proto Screw Shield is an assembled terminal point prototype expansion board designed to simplify connections for Arduino projects. It provides convenient screw terminals for Arduino I/O pins, allowing for secure and reliable wiring without soldering directly to the Arduino board. This shield also features a prototyping area for custom circuit building and can be used as an extension plate.

3. セットアップ手順

1. Prepare Arduino Board: Ensure your Arduino board (e.g., Uno) is powered off before attaching the shield.
2. ピンを揃える: Carefully align the male header pins on the underside of the Proto Screw Shield with the female header sockets on your Arduino board.
3. Attach Shield: Gently press the Proto Screw Shield onto the Arduino board until it is firmly seated. Ensure all pins are correctly inserted and no pins are bent.
4. 電源オン: Once the shield is securely attached, you can power on your Arduino board.

4. 操作手順

4.1 Using Screw Terminals

The Proto Screw Shield provides screw terminals for easy connection to the Arduino's digital and analog I/O pins, as well as power pins (5V, 3.3V, GND, VIN, RST, AREF). Each terminal is clearly labeled.

1. Identify Pin: Locate the desired digital (D0-D13) or analog (A0-A5) pin on the screw terminal block.
2. ネジを緩める: Use a small screwdriver to loosen the screw for the corresponding terminal.
3. ワイヤを挿入: Insert the stripped end of your wire into the opening next to the loosened screw.
4. ネジを締める: Tighten the screw to secure the wire firmly in place. Ensure the wire is making good contact and is not easily pulled out.

4.2 Using the Prototyping Area

The central area of the shield is a prototyping board (perfboard) where you can solder additional components to create custom circuits. This area is ideal for adding sensors, modules, or other electronic parts that are not directly compatible with the Arduino's standard headers.

• コンポーネントの配置: Place your components into the desired holes on the prototyping area.
• はんだ付け: Solder the component leads to the copper pads on the board.
• 接続: Use jumper wires or solder traces to connect your custom circuit to the Arduino I/O pins via the screw terminals or directly to the SMT solder points on the back of the board.

4.3 リセットボタン

A dedicated reset button is provided on the shield, mirroring the functionality of the Arduino's onboard reset button. Press this button to restart your Arduino program.

5. メンテナンス

• クリーニング： Keep the board clean and free from dust and debris. Use a soft, dry brush or compressed air for cleaning. Avoid using liquids.
• ストレージ： Store the shield in a dry, anti-static environment when not in use to prevent damage from static discharge or moisture.
• 接続チェック: Periodically check screw terminal connections to ensure wires remain secure, especially in projects subject to vibration.

6。 トラブルシューティング

• 電源/機能なし:
  • Ensure the shield is correctly seated on the Arduino board and all pins are making proper contact.
  • Verify the Arduino board itself is powered and functioning correctly.
• Loose Wire Connections:
  • If a component is not responding, check the screw terminal connection for that wire. Loosen and re-tighten the screw to ensure a firm connection.
  • Ensure the wire is stripped to an appropriate length to make good contact without exposing excess bare wire that could cause shorts.
• Short Pins (Potential Issue):
  • Some users have reported that certain pins (e.g., serial pins) might be shorted or not fully passed through on some shield designs. While this specific model aims for full connectivity, if you experience unexpected behavior with specific pins, carefully inspect the shield's underside and your Arduino's pinout.
  • Ensure no solder bridges or stray wire strands are causing unintended connections on the prototyping area or SMT points.
• Component Malfunction on Prototyping Area:
  • Double-check your soldering for cold joints or bridges.
  • Verify component orientation (e.g., diodes, ICs) and correct wiring to the Arduino pins.
