BREAD BOARD 8.5MMX5.5MM 400 HOLE

Product Specifications

• Tie-Points: 400 Total points (300 in the terminal grid + 100 in the power rails).

• Dimensions: ~85mm x 55mm.

• Structure: * 2 Power Rails: Located on the top and bottom, marked with red (+) and blue (-) lines.

  • 30 Columns: Each column has 10 holes (divided into two sets of 5 by a center “trench”).

• Material: ABS plastic with internal metal spring clips.

• Features: Self-adhesive back and interlocking tabs to connect multiple boards together.

How to Use It

1. Understand the “Invisible” Connections

• The Power Rails (Horizontal): The holes next to the red and blue lines are connected horizontally. This is where you plug in your battery or power supply so that “Power” and “Ground” are available across the entire length of the board.

• The Terminal Strips (Vertical): In the center area, the holes are connected vertically in groups of five (e.g., holes 1a, 1b, 1c, 1d, and 1e are all one wire).

• The Center Trench: The gap in the middle breaks the vertical connection. This is designed specifically for Integrated Circuits (ICs) and Chips so that the pins on the left side don’t short-circuit with the pins on the right side.

2. Building a Circuit

1. Power Up: Connect your positive wire to the Red rail and negative to the Blue rail.

2. Bridge the Gap: Place your main component (like an LED or a Chip) across the center trench.

3. Jumpers: Use jumper wires (like the ones in your photo) to “jump” power from the rails into the specific vertical columns where your components are sitting.

Quick Safety Tips

• Never connect a wire directly from the Red (+) rail to the Blue (-) rail; this causes a short circuit and can melt the board or damage your battery.

• Avoid forcing thick wires into the holes, as this can bend the internal metal clips and cause loose connections later.
