4 distinguish points Our breadboard have tight connections compare to other brand. Springs aligning perfectly with points makes the tightness of all 400 points are the same. Thus avoid falling part components. High quality print on board would not fade away easily. widely used among electronic experiments and point-to-point DIY IoT projects. 5 tie holes one each horizontal power path (solder free) for easy insert and remove of DIP, sensors, transistor, capacitor resistor and other components.
