    Excellent DIY Kit to get skills
    The excellent DIY kit. It allows to improve your skills. As a measuring device the oscilloscope has very limited capabilities. Anyway this simple oscilloscope is a fine kit to practice in soldering. Also it can be a useful tool for initial tasks.
    P.S. The firmware can be upgraded to the latest version.
    It is difficult to detect. The DIY kit will allow you get no much more it costs.

    Неплохой конструктор
    Отличный конструктор для тех кто хочет научится паять и получить в конце рабочее устройство.
    Практическое применение узкое, но все же для некоторых задач сгодится. К тому же в интернете полно сведений о том как доработать этот девайс.))
    Для тех кому это может быть важно. Данный конструктор - подделка согласно данным производителя. О том как отличить подделку от оригинала можно узнать на сайте производителя. Так как я брал его для обучения, то для меня это не так важно.
    Самый главный недостаток пожалуй это не корректные элементы в наборе. Два вида резисторов не тех параметров. Так что сборка устройства немного замедлилась. Но это тоже мелочь. Своего рода проверка на внимательность при сборке))
    Люди ни раз писали о том что после сборки при включении устройство сгорало. Причинами были косяки сборки или не верные параметры элементов.
    Будте внимательны и все получится)))

    Geek gadget
    The product is a geek gadget, nothing more. We have assembled the product as showed in te instruction, but the real values of the voltage aren't affidable. The measure of the alternate signals are correct in terms of frequency and waveform.
    Considering the price, is stupid to pretend the moon. I'm fine with the product, but it have some critical issues.

    Супер осцилограф
    Компактный размер, мобильность, можно питать от повербанка через step up.
    Собирается легко, часа за 3 собрал. Довольно увлекательно.
    Сначала шли помехи около 0 , но потом обновил прошивку с 40 на 60 и заменил резистор R11 с 1500 на 150 и стало всё отлично.

What power supply is needed for the board. I'm guessing 12vdc @ 1.5 amp, 5.5mm/2.5mm power plug, tip positive. Is that correct?

By Stephen Bepko Nov-17/2018 20:27:01

Hello Stephen,I apologize for my late response.It is 9V1A 5.5 interface.Thank you.

Is this the version DSO138-03 with all SMD parts presoldered?
