    Op het printje staat 'transistortester', maar dat doet dit bouwpakketje groot onrecht aan. Met de M12864 kunt u vrijwel alle onderdelen testen: weerstanden, potentiometers, condensatoren, spoelen, dioden, LED's, thyristoren, triac's, transistoren, FET's en MOSFET's. Daarnaast kunt u er ook frequenties mee genereren en meten. Uiterst eenvoudige bediening Het werken met de componententester is uiterst simpel. Sluit het te testen onderdeel aan tussen twee van de drie TP's (of tussen alle drie, natuurlijk) en druk even op de encoder. De tester toont eerst de spanning van de batterij en de waarde van de 5,0 V voedingsspanning voor de processor en even later verschijnt het resultaat van de meting op het scherm. Druk twee seconden op de encoder en het keuze-menu verschijnt in beeld, zie onderstaande figuur. Verdraai de encoder tot de optie 'Switch off' wordt geselecteerd en druk op de encoder. Het apparaat gaat weer naar stand-by. Als u niet zélf uitschakelt, gaat het apparaat na ongeveer 28 seconden automatisch naar de stand-by modus. Als u diverse componenten na elkaar wilt testen kunt u het gemeten component verwijderen, het nieuwe aansluiten en kort op de encoder drukken. Het apparaat start dan direct een nieuwe meetcyclus.

    I like it and recommend those kit. I already get on of those with the standard display 16x2 you found everywhere but I always wanted one of those with graphical display but there was only ready assembled ones. Now on banggod.com I found this and ordered it it is easy to solder also for beginners because it has only standard parts no SMT parts. The Kit comes in a small box and compared with the other kits I get this is much safer to send no parts was broken or pins was bended. Thanks to banggood.com

    As I use to build effect pedals for guitar, this device is extremely handy! Just insert your component, and it shows you the most important specs! And the pinouts! And as electronic technicians know, fets are not easy to test accurately. This little thingy does it all! Darlingtons, mosfets, it takes it all! I ordered 2 more, for at work. Very, very, very recommended!!! Thank you Banggood!!!

    Замечательный набор для того чтобы и в пайке потренироваться и получить полезное функциональное устройство. Не пугайтесь 400 вольтному конденсатору в комплекте, вероятно он идёт исключительно для того чтобы при первом старте устройство было чем откалибровать (что очень предусмотрительно со стороны китайцев). Упаковано было хорошо, но ноги АТмеги пришлось долго подгибать до размера фишки под неё, слишком уж растолстела пока её втыкали в паролон видать. Всё меряет адекватно, сборка заняла ровно час. Запускал от двух 18650 в последовательности (заявлено что работает в довольно широких диапазонах напряжения, что тоже порадовало).

    I had a great time building this kit. Took about 90 minutes to complete. When I was done, there was a 220uF capacitor left over. I went crazy looking for a spot on the board I may have missed but the board was full. Eventually, I learned that the capacitor was included for the sole purpose of calibrating the device! The device came up right away, on the first attempt. I did not have to do any troubleshooting. There is one odd issue with the selector knob - when I turn it one click up or down, menu items cycle one full page up or down (instead of going up or down by just one row). Also, there are a ton of spelling and grammar errors on the screen. I plan to download the source code and fix these errors. I tested some capacitors and the values were very close. The device was able to detect fractions of ohms, although the instructions say that resistances under 200 are not reliable. This is really a neat little device. Once I get the menu selector working, and clean out the spelling/grammar errors, I'd like to purchase the plastic case for it. **Note, the instructions state that the LCD display headers connect from Pin5 to Pin12. The pictures show this as well. Be careful because Pin5 is actually the fifth pin from the right if you are looking at the front of the display board. The front only has the number "1" showing for the right-most pin. In the back, however, the board shows pin names that look similar. Looking from the back, Pin13 has the name D5, so it is tempting to solder headers incorrectly if you look at the names in the back. For the display board, follow the pictures!

    It comes in a bag with anything you need to assemble a Very Good Component Tester, who covers the majority of basic passive and active components! Anything you want to recognize the value of a resistor or a capacitor or any other passive component is here. In the Semiconductor domain works well and recognize all the basic types and characteristics of the component! With slim nozzle to the soldering iron and some free time to spend, I managed to complete the assembly of the kit in less than one hour. After the soldering of the components you mast clean the remaining resin with acetone and a used toothbrush (especially in the around the IC area). I found this Kit an Excellent exercise for beginners who want to learn how to solder a KIT. Delivery Time was fast and Seller’s service was VERY GOOD!!! So YES! I strongly recommend this product and the seller!

    Il manque des connecteurs pour éviter les courts circuits. Mettre des barrettes picots va parfaitement.

    Although I am an experienced electronics engineer, this kit is easy to assemble for anyone with basic soldering skills. The downloadable instructions (in PDF) are pictorial and easy to follow. The assembled unit worked first time and will be a valuable little unit for testing many components. Have also ordered the companion housing supplied by Bangood as the soldered side of the board could be easily shorted by accident.

    This is the second purchase. I confirm easy to assemble and great laboratory tool. This time I tested the frequency generator and frequency counter functions. The results seem to me satisfactory (see photo).

    Excellent laboratory tool to replace (or in addition to) my old, worn out, selfmade transistor tester. Went through my entire stock of saved parts and discovered quite a number of displaced items. BT139 triacs are seen as NPN transistors or thyristors, however. But my tester was not able to test those components at all.
