DEV-11723

Sometimes you've got way too many inputs, or outputs... or both. How are you going to get them all connected to your Arduino? The Mux Shield, that's how. The Mux Shield II from Mayhew Labs is an upgrade on their previous Mux Shield which makes it possible to route up to 48 analog and digital inputs or digital outputs to and from your Arduino board.

The Mux Shield II improves on the original by moving all of the I/O pins to the end of the board, thus allowing you to add one big connector and hook up a ribbon wire or similar cable solution. This also gets the pins out of the way so that the Mux Shield can be in the middle of a stack, with a shield on top of it, and you can still get to the I/O pins. The pins are arranged into three rows of sixteen and each row can be individually set as a digital input, a digital output or an analog input from the Arduino sketch! Further increasing the flexibility of the board, Mayhew Labs added solder jumpers to the bottom of the board that allow you to shut off this software control feature and "hard wire" the functionality of each row, freeing up the associated Arduino pins for other shields in the stack.

The Mux Shield uses TI 74HC4067 analog multiplexers (mux’s) for input functionality and TI 74HC595 shift registers for output functionality. Don't worry if that's jibberish to you, the included Arduino library wraps it up and makes it very easy-to-use.

The shield comes without any headers so be sure to pick up some stackable shield headers!

Fetch Perfection
Size: Medium (2.5"), Style: Fetch Pack 2
If you’re anything like me, fetch is the ultimate game with your furry companion. The Chuckit! Dog Fetch Ball Medley has taken our playtime to the next level with its variety and durability. This 3-pack of medium-sized, ultra-rugged balls is perfect for endless games of fetch without worrying about wear and tear. I love how each ball has a unique texture and color, keeping my dog engaged and excited every time. The medium size is just right for energetic dogs, allowing for long throws and big leaps. Plus, the rugged design means these balls can withstand even the most enthusiastic chewers and rough play sessions, making them a great investment for active pets. However, the vibrant colors can sometimes make them easy to lose in green grass or sandy beaches, but a good game of hide-and-seek with your dog is a small price to pay for such fantastic fetch balls. Additionally, while they’re durable, no ball is completely indestructible, so occasional replacements might be necessary for the most aggressive players. Overall, the Chuckit! Dog Fetch Ball Medley is a must-have for any dog owner looking to enhance their playtime. They’re fun, durable, and keep both you and your dog entertained for hours. A solid 5-star rating for their quality and variety, with a tiny star lost to their occasionally elusive colors.

great ball!
Size: Medium (2.5"), Style: Fetch Pack 2
My pitbull LOVES these. She is a power chewer and tough on balls and toys and tends to go through them insanely quick. She is still on her first ball out of this pack and its been at least two months. It is a little small for her mouth but she doesn’t seem to mind, as it has quickly become one of her favorites. Not a loud ball and it doesn’t usually make that wet chewy noise when shes going to town on it which is huge for me😂😂 Safe for my pittie so i’d imagine a smaller dog would be just fine.

Border Collie Approved: Easy to Clean, Durable, and Great Bounce
Size: Medium (2.5"), Style: Fetch Pack 2
These are the best balls out there for dogs. These fit great in the chuck-it ball launcher, which we need to wear out my border collie. They fit her mouth properly and, most importantly, do not absorb all the spit or water after a good rain. They are quick to clean off and have good weight so you can let them fly! Furthermore, they bounce well, which is perfect for my dog that likes to catch them on a bounce. The ball is a strong rubber, so should not be easy to chew up. I've used these for years, and the only time I've had to replace them is when one gets lost in the hay field. I highly suggest these as replacements for the common tennis balls.

Treats and plenty of ball throwing with these doggie toy
Size: Medium (2.5"), Style: Fetch Pack 1
I have actually purchased these twice already. I love the one that glows in the dark but it still got lost in my yard lol. My dog is a big breed half pitt/Labrador so she did chew through one of them already. I play ball with her every single day but I DO have to take them away from her because she will destroy them. They are great to add in treats as well, that was one of the my favorite things about them as well. They do last just if you have an over zealous chewer do not let them keep them for long periods of time. They are a good value for the price. Buy them your dog will love it!
