I mean the 3V side of the cable with the VCC, IN, and ground It's not a good idea to put 12V on this side, since this model of relay does not support it. Alternatively, they make a version of this relay suitable for 12V that both the VCC and IN is capable of receiving.
A little over 1 percent. The width is about 25CM and the height is about 6 inches. This is 6CM,1. A 7x7CM board
While I have not measured the diameter of the holes, a #2-size does the job An hex screw size 56 fits and a #4-size bolt Having a chest measurement of 40 is just slightly too large. As a result, if you mount it with #2 screws, you will
The relay will be controlled by the voltage applied to VCC, Ground, or 0 volts applied to GND, and the value of "IN" will determine its state. Whenever you connect the relay "IN" to either VCC or GND and disconnect it again, the relay should sound like it is clicking.

To be honest, it's a waste of time. In one anti-theft device, 5 modules are bundled I did receive a static bag that was a little loose, and though the product arrived in fine condition, at least foam insulation would have been nice. On the other hand, the product works well at 3v3 using an Arduino or an Espruino. I was able to achieve 100% expected results for both an active and an empty load 2hr test. When the main voltage was reduced to 5vDC, I was not encountering any issues. So far, no missing components or malfunctions have been noted (as I mentioned in one of the testimonials). The black PCB mask is sleek, I feel a satisfying "click" when switching, and above all, I am extremely satisfied (*packaging). I would like to thank the vendor and the buyers and makers If you are considering a single load switching project, then these will fit your needs.

Signals draw 2 volts from a 3V supply. My microcontroller will work with this because the current draw is 56 mA and the voltage supply is 98 mA. The schematic I have attached is accurate to the best of my knowledge. It might be possible to power the signal with 5V, but the voltage should be 3V. You may not believe me, but I can attest to the power of 7V.
The purchase process is simpler than the construction process. I tested every combination of 3 out of the 5 modules, and they all work. The input voltage is 3v and the Vcc voltage is 5v. The optometrist may examine patients to determine if they are You don't have to worry about your microcontroller being fried by spiked return voltage because an isolation circuit protects it. It allows you to power the relay from another source with the jumper. Ok, I don't know why I would need that, but I guess I can go ahead and use it.
The esp8266 can be used with this. Instructions are missing, but there are some jumpers. I was only able to get it to work if both windows were My first attempt did not work because of one board that wouldn't adhere to the surface. Verify that the jumpers are in good condition.
Please send us the schematic along.
Here is a list of all returned items.
The device is very useful with EsP 32 since it works with In contrast to relays that operate at 5 volts, 3 volt relays use 3 volts.
