Description

The LLT-900 Logic circuit Lab offers a unique entry into the world of microelectronics. The system combines simple, easy to use, logic gates with a versatile solderless breadboard area.

By using the clearly marked built-in logic gates, students new to digital electronics can implement logic circuits in a matter of seconds. As confidence grows the student will naturally progress to using more complex logic integrated circuits on the undedicated breadboard area.

This unique approach enables the unit to be used by the absolute beginner, yet it may also be usefully employed in advanced project work. The many outstanding features of the Logic Lab, combined with its ease of use and robust housing, make it the first choice for those wishing to introduce students to logic gates for the first time
