Solderless breadboards are suited to low-frequency analog and digital circuits.

As a general guideline, reliable operation is typically limited to signals below 10 MHz. Above this, the parasitic capacitance and inductance of the contact springs and bare wires introduce noise, signal degradation, and unexpected behaviour.

General current guidelines allow for a maximum of 1 amp. Any current above this can cause voltage crops and excessive heat that can cause loss of spring tension and physical damage to the plastic housing.

On many breadboards each power rail is divided into two electrically separate halves at the midpoint of the board. BusBoard’s breadboards have a single continuous power strip on either side of the breadboard. Feedback from engineers over the years has indicated that the preference is to have a continuous power rail on their breadboards.

Yes, linking multiple breadboards together throughout your project can be helpful.

BPS full-length BreadBoards (BB830, BB1660, BB630, BB100R) can be used side-by-side using the interlocking dovetail connector on each end and half-length BreadBoards (BB400, BB300, BB50R) can be used side-by-side as well as top-and-bottom. This is a convenient way to expand your working area without rewiring.

Use solid core wire in the range of 22 to 26 AWG. This range provides good grip in the contact springs without putting excessive force on them. Very thin wire (28 AWG or finer) may not make reliable contact; wire that is too thick (20 AWG or heavier) can damage the contacts over time.

BreadBoard Quality Criteria:

All BPS BreadBoards have adhesive tape pre-applied to the back, making it easy to mount them to any clean, flat surface: an enclosure panel, a piece of acrylic, or a wooden board. For a more rigid backing without committing to a permanent surface, use the included metal plate*- just peel the paper liner and press the breadboard to the plate.

The BPS BreadBoards have adhesive tape on the back to attach them to your benchtop worksurface, pegboard, or enclosure. You can use the breadboard as-is.

To extend the use of your breadboard, prevent damage and punctures, we have included an optional metal plate to provide a permanent solid backing. Just peel off the paper liner and stick the breadboard to the metal plate.
