Banggood

I've got a new revision with CD4011 instead of NE555 shown in description. Anyway it does it job so I plan it to control a NC solenoid valve. + easy soldering - no 12V power connector included

Good quality. Fast shipping. Everything as described. The board I have collected but have not tested it :) Хорошее качество. Быстрая доставка. Все как описано. Плату я собрал но пока не тестировал :)

схему быстро спаял, заняло минут 15, и сразу заработало, никаких танцев с бубном, хороший товар, покупал для автоматического долива воды в самодельный увлажнитель воздуха.

Even the school student can collect. Everything is intuitively simple. About the relay - it is declared 10A, but that that I doubt. 5A holds well.

Si ninguna queja de este articulo todo en orden componetes en orden y 100% funcional.

This item is as described and of good quality. The instructions are in Chinese, which may be an issue if you can't read Chinese. Construction is easy and straightforward, so being unable to read the instruction sheet is probably not a big deal.

easier than expected to assemble and solder. quality is fine, not perfect, but fine; the shipping was fast and the product arrived safe. it works as it should

Kitt ist sehr gut beschrieben für den Problemlosen zusammenbau. Die Funktion ist einwandfrei.

MANUAL DE LA TARJETA VIENE EN CHINO, PERO NO HAY PROBLEMA PARA EL ENSAMBLE. BUEN PAQUETE PARA INICIAR CON LOS CHICOS
