Enhance your Arduino projects with the HKM-953043 24V Single Channel Relay Module. This highly functional module is designed to offer reliable control across various applications, making it an essential tool for hobbyists and professionals alike.

Featuring advanced photocoupling isolation, this relay module provides excellent driving capability and stable performance, ensuring your setups remain efficient and dependable. The high-quality relay supports a maximum load capacity of AC 250V/10A and DC 30V/10A, making it suitable for a range of devices and projects.

Ease of use is a priority with user-friendly wiring terminals that simplify connections. The module is equipped with clearly marked interface points: connect the VCC to the positive pole of a 3.3V power supply, the GND to the negative pole, and use the IN port for control signal input to trigger relay activation.

The HKM-953043 also boasts a fault-tolerant design, ensuring that if the control line is broken, the relay remains inactive, providing an additional layer of reliability. Its output options include a normally open (NO) interface for activation, a common (COM) interface for relay operations, and a normally closed (NC) interface for deactivation.

Packaged as a single relay module, the HKM-953043 is not just a component; it's a gateway to enriching your electronic projects with superior control capabilities. Make it a key part of your toolkit today and unlock new possibilities in your designs.

Great for dogs
Color: blue
My dog is obsessed with this! I put plain yogurt thinned with homemade broth in it and he’s entertained for a good 15 minutes, as well as being fairly calm afterward.

Great bowl, would love this in a larger size
Color: blue
This is a great way to treat your dog! I filled it with a bit of plain yogurt drink diluted with water, and my dog absolutely loved it. It only took him about 3-5 minutes to finish it, but he’s about 60lbs, so maybe a bigger size bowl would be better for him. Max capacity of this one is 190 ml. You do have to monitor your dog with this bowl - mine tried to dismantle the bowl when it was empty, trying to get more out of it. Overall I think it’s a fun way to get your dog to drink a little bit more with diluted yogurt, broth, etc.

My dog loves it!
Color: black
Kudos to whomever created this! I have a super attached (med) dog that follows me from room to room alllll day. The first time I put this down he went right for it and didn’t even notice i had left the deck. He is very food driven. I used bone broth and pumpkin puree, which was a hit but once I used the apple sauce… HUGE hit. My only complaint is that it doesn’t come in an XL size. My dog can empty it in under 3 minutes..so he doesn’t get relaxed or sleepy! it does splash out a bit from the top so I use it on his food mat or outside..my sister can’t stand the noise the ball makes. I wasn’t diluting enough so the ball doesn’t move smoothly in the video, but it really does work! The cover is very well made and sturdy. I didn’t notice it sliding around at all. My dog also did not try to get the ball out (loves to tear apart toys) or tip it over, but I could see that happening. I wouldn’t use unsupervised unless you have a small dog. Please make a larger size!!!!

Works but the bowl is wacky
Color: blue, Color: blue
This slow feeder is actually a very good idea and my dog likes it. I blend plain, unsweetened yogurt with a little powdered pumpkin & apple pectin and thin it down with water so the roller ball can easily rotate. It's sturdy and it doesn't slip on the floor, which is good. However, I give it only three stars because the bowl inside is a ridiculous design. Instead of the inside surface being a gently sloping, smooth surface, the "legs" underneath protrude up through the inside (see photo). It makes stirring and cleanup much more difficult than it needs to be. Presumably, it's made using injection molding so it should be easy to design it with a smooth finish.

Happy licking brain stimulation!
Color: black
We have a very active 1 year old field golden and we needed something else to stimulate her brain. This has worked out beautifully for that. At first she would want to try to pick it up or move it with her paw but a few corrections and training and she’s learned to just lick at it. It stays well planted in the floor and doesn’t tip over. I had to knock it one star for its ease of use and cleaning. The inside bowl has “fins” inside that make it difficult to stir things up and mix together or to clean. Other than that minor gripe we really love it and would buy again. The enjoyment our girl gets out of is definitely worth the money. It’s been through the dishwasher several times and show no signs of wear and tear so it’s well built. Happy licking!!!
