While the initial cost is higher than generic alternatives, serious makers agree the superior quality and the time saved avoiding troubleshooting fully justify the investment. It is viewed as durable, essential lab equipment.
Know before you buy
This board provides a total of 2250 tie points, which is equivalent to three standard-sized breadboards combined, giving you plenty of space for complex projects.
It comes pre-mounted on a stable metal plate. This base includes non-slip bumpers to keep the board firmly in place on your desk while you work.
Yes, the power rails are contiguous. This design simplifies power distribution across your entire circuit without needing extra jumper wires to bridge sections.
The upgraded spring clips are designed to provide a smoother, more consistent feel when plugging in and removing components, which helps prevent the loose connections often found in lower-quality breadboards.
Absolutely. The four colored posts are integrated into the metal plate to provide convenient, reliable connection points for your power supply leads.
The breadboard itself measures 175mm x 145mm, while the entire assembly including the metal mounting plate measures 221mm x 183mm.
