Choosing a breadboard

A breadboard lets you wire up a circuit without soldering: components and wires clip into metal contacts, and you can undo everything to start over. The choice comes down first to the number of contact points, in other words how much room you have available.

  • 170 points (SYB-170): very small, for a sensor, a transistor, or a build that needs to fit inside an enclosure. Available in several colors to tell your blocks apart.
  • 400 points: a common size for a circuit with one or two DIP ICs.
  • 830 points (MB-102): the go-to choice for working with an Arduino board or an ESP32 and several modules at once.
  • 1660 and 2390 points: several boards joined together with power rails, for a long build or a lab bench setup.

Also check the side power rails (+ and −) and the adhesive backing if you plan to mount the board on a platform. For clean power, a module such as the MB-102 3.3V 5V power supply clips directly onto the rails and avoids drawing 5V straight from the board. The BB-01, BB-2T3D-01, and BB-4T7D holders combine a breadboard and a build area on a single base. For wires and accessories, see the Prototyping category.

Frequently asked questions

Which breadboard should I use to get started with Arduino?

An 830-point MB-102 works well: it leaves room for the board, the modules, and the jumper wires, and its two power rails simplify wiring. A 400-point board is enough for simple builds.

What is the difference between 170, 400, and 830 points?

It is just the number of contact holes, in other words the mounting surface. The internal principle stays the same: rows of five linked contacts, separated by a center channel for DIP packages.

Why use a power module on the breadboard?

It supplies regulated 3.3V and 5V to the rails without overloading the development board's regulator. This is useful as soon as a motor, a display, or several modules draw current at the same time.

What makes the price of a breadboard vary?

The number of points, whether it has a metal base or separate power rails, and the quality of the internal contacts, which determine how well it holds up over time after many connections.

Can you solder on a breadboard?

No, a breadboard is meant for temporary connections. To make a build permanent, move to a perfboard or a printed circuit board.
