Solderless Breadboard allows components to be easily connected together into circuits and used time and time again for experiments and prototyping. This transparent topped version allows visibility of the contacts and how they are connected together, making it ideal for use in training and education. * Solderless concept allows components to be used again and again * Ideal system for teaching electronic systems and circuit design * Components are plugged into the board and are retained by double-leaf phosphor bronze nickel-plated spring contacts * All contact positions are clearly defined on an coloured alphanumeric grid * ABS polymer board mounted on an adhesive foam base
