These large solder-less breadboards make it easy to try out things hooked up to a JeeNode, and to build up elaborate electrical circuits with many components and ICs, particularly in combination with Wire jumpers.
The boards have a self-adhesive backing, with 2x 63 rows of interconnected pins (5 per row) and two long interconnected rows on both sides for power distribution – 830 pins in total.
For even larger projects, you can combine multiple boards through the interlocking notches on both long sides.
Each breadboard is ≈ 54 × 165 mm.
