A breakout board for a mini breadboard with 170 tie points, and 34 distinct connection groups (1-17 A and B). This is very convenient for integrated circuits or any other electrical component which you cannot directly clamp into the spring contacts but which fits into a breadboard.
This sub-board comes ready-made, meaning the mini breadboard is already soldered onto the PCB. If you want to solder it yourself you can purchase the cheaper Mini Breadboard Kit.
