A 400-point solderless breadboard for quickly building and testing circuits without soldering. Perfect for prototyping with through-hole components and up to #22 gauge wire. When you're done or want to change your circuit, simply pull the components out and start again. Key Features 400 Tie Points – Plenty of space for small to medium circuits Solderless Design – No soldering required, fully reusable Interlocking Tabs – Connect multiple breadboards for larger projects Adhesive Backing – Masked adhesive to secure the board to your project Standard Spacing – Accepts most through-hole components Specifications Tie Points: 400 Wire Gauge: Up to #22 AWG Mounting: Adhesive backing Ideal For Circuit prototyping and experimentation Arduino and Raspberry Pi projects Electronics learning and education Testing components before permanent assembly Tip: For best results, use solid core wire rather than stranded wire when breadboarding.
