Velleman VTBB3 juottamaton koekytkentälevy 400 kontaktipistettä valkoinen

The Velleman VTBB3 is a 400-tie-point solderless breadboard with a self-adhesive backing and interlocking edges, making it easy to build and expand prototype circuits without soldering.

Highlights

• 400 total tie points: 300 in the terminal strip and 100 in two distribution strips
• Nickel-plated phosphor bronze contacts accept 20–29 AWG solid or stranded wire
• White ABS body with standard 2.54 mm (0.1 inch) pitch
• Self-adhesive backing for secure mounting on a project base
• Interlocking design allows multiple boards to be snapped together

In daily use

Insert DIP ICs, resistors, capacitors, and jumper wires directly into the spring contacts. The two power rails run the full length of the board, simplifying power distribution. For larger projects, connect multiple VTBB3 boards side by side using the interlocking tabs.
