100pcs 20Ma F5 5MM Diodo LED branco ultra brilhante transparente
US$6.07 US$5.99

Q: What is forward voltage? Specs say 1.8-2.2volts, but photo shows coin cell, so either 1.5 v coin cell or 3 volt coin cell. All of the other white LEDs that I have are rated 2.8-3.2 volts. What is the forward voltage for these white LEDs?

AWG 22 is good for 9 volt circuit, where flexible wire is important.

Good value. I took one apart to show my 9-15 year old students the inside of a solderless breadboard.

The description said "Transparent" lens. The item delivered has a lens color that is red (see photo). I tested several of the LEDs with red color lens, and they work very good. The item delivered to me did not match the description.

Q: Photo shows two resistors and no mic. Circuit diagram shows three resistors and one mic. Does the DIY kit include all three resistors and the mic? Does Banggood sell mic as a separate part?

perguntado por David sobre 2018-10-28 07:49:03

Extrud Yes, it have all three resistors and the mic

The description says "Self-locking On / Off Switch". None of the switches lock. They are all momentary contact switches. Because the switches do not perform like the description, the Value is one star. The switches look like the photograph, so the appearance is 5 stars. They are all good quality, correctly assembled and smooth motion, so Quality is 5 stars. I need self locking switches. These momentary switches do not meet my needs.

David Are the pins on the correct distances for a solderless breadboard?

Product OK, but no datasheet with it. Double inverter switch and symmetric. See my little schematic. Product not enough packed or badly manufactured! +20% of the package have their legs bend, as you can see on the picture. Hope there are no internal stresses resulting on the switch.
