400-Point Breadboard

A 400-point breadboard is a versatile and essential tool used for prototyping electronic circuits. It is designed for easy assembly and testing of electrical components without the need for soldering. The breadboard has 400 connection points (hence the name), arranged in a series of rows and columns, allowing users to quickly create temporary circuits for testing, design, and experimentation.

The board is equipped with a grid of holes that are internally connected in horizontal and vertical strips. These connections make it simple to insert and remove components such as resistors, capacitors, diodes, transistors, and ICs. Breadboards are widely used in electronics education, hobbyist projects, and circuit design testing, providing a safe and non-permanent way to build circuits.

Specifications of 400-Point Breadboard

Physical Dimensions

• Size: Typically 6.5 x 2.0 inches (165 x 50 mm)
• Color: Usually white or translucent plastic with black/blue markings
• Material: Plastic (ABS or similar durable materials)
• Connection Points: 400 (arranged in multiple rows and columns)
• Rows: 5 rows of 5 pins each, for a total of 25 horizontal strips
• Columns: Multiple vertical columns for easy connections

Pin Layout

• Power Rails: Two power rails (usually labeled with + and -), used for distributing power across the circuit, making it easier to connect power sources like batteries or voltage supplies.
• Terminal Strips: The main area for inserting components, divided into 5 horizontal sections, each with 5 holes, allowing components to be inserted in a line.
• Connection Method: Internal metal clips run underneath the board, connecting the holes in horizontal rows and vertical columns.

Electrical Characteristics

• Maximum Current Rating: Usually 1A to 2A per contact point (depending on manufacturer)
• Maximum Voltage: Typically 50V to 100V
• Contact Resistance: Typically low, but depends on quality
• Recommended for Low-Voltage Circuits: Works well for circuits involving low-voltage, low-power components

General Features

• Compatibility: Compatible with standard 0.1-inch (2.54mm) pitch components
