Breadboards are one of the most basic fundamental  thing  for the students  when learning how to build circuits at early stage. Solderless breadboards enable  us  to test your circuit design without wasting time soldering devices to an ordinary printed circuit board. If the circuit doesn't work properly, you simply change the circuit by removing components and jumper wires and reinserting them somewhere else or by replacing components. This project board features include two breadboard mounted on a front panel with 1680 tie points provided with two fixed output DC power supplies one is  ±5Volt , 2nd is   ±12V . One clock pulser, Power switch with LED light. Complete unit housed in ABS plastic cabinet. Complete in all respect.
