A Mini Breadboard is a type of prototyping board that allows you to easily connect and test electronic components without the need for soldering. It typically has a set of holes, called tie-points, where you can insert the leads of electronic components such as resistors, capacitors, and transistors, and connect them together with jumper wires. The Mini Breadboard you mentioned has 170 tie-points, which is a relatively small number of tie-points, and its dimensions are 35mm x 47mm x 8.5mm. The small size of this breadboard makes it portable and easy to use for small projects.

This tiny breadboard has 170 tie-points and is good for small circuits and broadboards dedicated to using a specific IC or two. Multiple breadboards can interlock to form a larger breadboard.
