mastromarco74 You can find details on manufacturer website (espressif.com). Some changes in the different models attain to amount of SDRAM for example, but for most pratical use you might not experience any difference.

MaiMariarti The description should've been more clear. It takes input from a 5V supply, and charges a Li battery. It then boosts the Li battery voltage to 12V. A more appropriate headline would've been " 5V to 12V boost convert UPS using a single 18650 Battery".
MaiMariarti I have the same problem. How did you install the sensor in your picture? Did you have to modify the firmware? I will never buy from Banggood again. They used to be good, and like others, they have fallen.
Blanken Then you need to contact the banggood team to buy or get the free replacement: https://www.banggood.com/Contact-Us_hi111

MaiMariarti Does your go down to 2mA?Mine goes as low as 42mA but bellow that, its 0mA !!
MaiMariarti Good review. Can you share the link to the Chinese document? Thanks
MaiMariarti Tell me is they can pass more than 5 Amps. I want to buy them for 10 Amp power supply. But not sure if they are real or fakes.
MaiMariarti Were you able to drive them at 5 Amps?Did you check to see if they are indeed short circuit protected?

toplec The illumination is provided by a neon bulb, not an LED. The two silver pins are the switched pins (attach your load across these), and to light up the neon indicator light, apply 120V - 240V between the gold pin and either of the silver pins. Neon bulbs are not polarized, so it doesn't matter which side is hot. Note that the switch is internally a DPST switch because it doesn't matter which silver pin you use for powering the neon bulb. I posted a review with an image of the schematic of this switch. Please see that for more information.
