Know before you buy
This breadboard is designed to securely hold solid-core wires ranging from 21 to 26 AWG. Using wire within this range ensures a snug fit in the phosphor bronze contacts without damaging the internal springs.
Yes, the Pro Series 400 breadboard features interlocking tabs on the sides, allowing you to snap multiple units together to expand your prototyping area as your project grows.
Yes, this model features two full-length power rails that provide continuous power distribution along the entire side of the board, making it easy to supply voltage to multiple components.
No tools are required. The breadboard is designed for solderless prototyping, meaning you can simply plug your components and jumper wires directly into the 0.1" spaced tie-points by hand.
The contacts are made from high-quality phosphor bronze, which is chosen for its excellent spring properties and resistance to fatigue. This ensures that your connections remain reliable even after repeated insertions and removals of components.
