(DIYODE October 2017) This new 3 state logic probe design by DIYODE magazine includes power connection leads and utilises the LM339N chip to provide logic states when checking TTL or CMOS circuits, output pins on boards etc. A simple logic probe can be an excellent tool for diagnosing 3.3V or 5V circuits in your projects. It will indicate low and high logic states, plus a shift between states. The kit is provided without a case, however a design for one is provided by DIYODE magazine, which you can download at the link below. This can be 3D printed by a third part provider or using your own 3D printer.
