I picked four of these up for testing with custom-built lock boxes. They aren't expensive for what they are, but the shipping was ridiculous! Originally I was going to buy two, but the shipping cost more than the sub-total!

One of these modules is slated for testing ASAP. I need to go over the specifications for these modules before I decide how I am going to drive them. I'm not really a fan of the application example from the DFRobot website (https://www.dfrobot.com/product-1856.html?srsltid=AfmBOoqktICSzmhQ31BjY6YTexEVD-imlpkVGGVIy3tCR-rn6iXYnDES).

This is what comes in each package. It connects directly to the power source as well as to the control circuit.
Are you planning on putting these on your house's doors? Will this be part of your home control security system?

While these are pretty solid units, for my purposes they're intended for a lock-box and / or access door (non-human). When these unlock, they sort of eject the metal loop. The metal loop must be pressed back into the latch to lock it again. So in a way these work similar to the Amazon lockers in that the door opens itself, then must be manually closed.
