• Color: White body with colored power rail markings (red/blue typical)
• Mounting: Self-adhesive backing (typically)
• Operating Temperature: -20°C to +80°C

Layout:

• Main Terminal Area: 63 columns x 10 rows (2 groups of 5 rows each)
  • Each column has 5 internally connected points
  • Center gap for DIP IC placement (0.3" spacing)
• Power Distribution Rails: 4 rails (2 per side)
  • Red (+) and Blue (-) markings
  • 50 connection points per rail
  • Typically not interconnected between top/bottom

Features:

• Solderless design for reusable connections
• Standard 0.1" pitch compatible with most components
• Self-adhesive backing for secure mounting
• Multiple breadboards can be connected side-by-side
• Dual power rails on each side for voltage distribution
• Clear hole numbering (columns 1-63, rows a-j)
• Durable spring contacts maintain connection integrity

Compatible Components:

• DIP integrated circuits (up to 28 pins)
• Resistors, capacitors, LEDs, diodes
• Transistors, voltage regulators
• Sensors and modules with 2.54mm headers
• Jumper wires (solid core, 22-24 AWG recommended)
• Arduino, ESP32, Raspberry Pi Pico with headers

Applications:

• Circuit prototyping and testing
• Arduino and microcontroller projects
• Electronics education and learning
• Sensor testing and development
• Analog and digital circuit design
• Power supply prototyping
• Signal processing experiments

Usage Tips:

• Use solid-core wire (22-24 AWG) for best connections
• Avoid excessive insertion/removal cycles on same hole
• Bend component leads at right angles for neat layout
• Power rails typically need jumper connection between top/bottom sections
• Clean contacts periodically for reliable connections

Typical Setup:

• Connect power supply (+/-) to power distribution rails
• Insert ICs across center gap (pins in separate groups)
• Use jumper wires to connect components
• Build circuit row-by-row for organization

Important Notes:

• Accepts wire diameter 0.3mm - 0.8mm (20-29 AWG)
• Solid-core wire recommended (stranded may cause poor contact)
• Do not exceed 1A per power rail
• Component leads should be straight and clean for good contact
• Power rails may not be interconnected - use jumpers to connect top/bottom

Perfect for students, hobbyists, makers, and professionals for rapid circuit prototyping and testing. Essential tool for any electronics workbench.
