New version of famous component tester I tested some time ago has arrived. M12864 Graphical RLC/ESR Transistor Tester With AVR-ISP Socket MOS/PNP/NPN M328 is an an updated version of famous M168 component tester. This new model can test all the same components as the earlier version, plus it can do for example in-circuit capacitor ESR measurements. Also the new model with graphical display can show the component pinout in more readable format.
The kit is based on Atmel 328 CPU (same as used in Arduino Uno boards) and adopts 12864 dot matrix LCD display richer content, illustrations. This tester can measure transistor, MOSFET, diode, resistor, capacitor, inductor and also the ESR of the capacitor. This new M12864 version is also from German author Karl – Hans design (Karl-Heinz Kübbeler’s ttester project) like the earlier model.
This Graphical RLC/ESR Transistor Tester With AVR-ISP Socket MOS/PNP/NPN M328 board has standard Atmel AVR programming connector which allows easy future software updates as they may appear.
The pictures below show my quick review of the device. It seemed to work well. The device has ZIF socket for component measurements (the owner of this device had also solvedred his own test leads to the circuit board):
I found a a two part YouTube video of the Kit version of the M12864 tester so enjoy it for more details:
