The 555 Solderless Breadboard is a user-repairable breadboard. You can remove the back and replace the contacts if they become damaged. Now there is no need to endure dead spots. The board can be quickly placed back into service. The CT2044 PRO 555 Accessory Maintenance Kit includes the required replacement contacts.

The basic PRO 555 Solderless Breadboard is a small, durable, rectangular, white polyester plastic board containing two side-by-side zones of five contacts by 43 rows (a total of 430) for ICs and components. It also includes five lines of 5 × 5 contacts (a total of 125) for power and grounding. You can connect PRO 555 boards together into a matrix if desired. The rear plate is made of clear polycarbonate so you can easily view the contacts.

The breadboard comes conveniently mounted on black anodized aluminum panels for larger circuit designs. Unique binding posts (five in total) facilitate user power, ground, and signal connections. The binding posts are uniquely designed to work with both standard and sheathed banana plugs. Each panel comes with a convenient circuit-tracing pad to develop and document your design.

The CT2043 individual breadboard unit costs $16.90. Pre-build configurations start at $46.80 each.
