Q: can I use it for mechanical switches? (computer keyboard)

尋ねた BG533754024 に 2020-10-21 08:28:19

Bricola Hello, personnaly I wont use any grease for the computer keyboard switches. It is better to clean them 1st from dust and then eventually with a contact cleaner but I do not think grease is recommanded. This grease is for the mechanical parts (in movement) of printers, specialy like (and for) gears.

Bricola Those remarks about bubble-wrap (written down by aecarcu) have to be sent to the customer support, this is regarding the packaging and not the product quality itself. Most of the time Banggood material arriving with protection.This item I've received in the past was in a cardboard box with strong plastic, depending of packaging protection (or not) of the sender factory and the 'special' care of the carriers, the material could be strongly badly handle. Since 5 years I do only have one broken item.

Q: can i make variable power supply by use this buck converter?

尋ねた Ritu に 2020-06-24 06:31:48

Bricola Depends what you are having for source power. It is a buck (step down) module, the DC input must be greater that the desired DC output. If you add a Amp-Volt display and change the 10k lin trim pot to external 10k lin pot, is can be use as a variable power supply. I will advise to add a cooling fan if you are using at high Wattage.

Q: Are these isolated?

尋ねた tedhancock68 に 2020-07-10 02:22:24

Bricola No, this kind of module are not isolated, means the - (minus or gnd) line is common (you can see this on the back circuit picture). The + (positive) line pass through the IC MP2307DN, which is not optocoupled.

Bricola You may have a look by googling for (thanks to grumpy_gnome that gives this info in this forum). According to the specs of this datasheet, backlight current is about 180mA. By 4.2V means 0.756W. Hope this help.
