WRL-13632 Simblee BLE Breakout Board is Programmable allowing to add mobile app functionality via Bluetooth Low Energy (BLE, or Bluetooth 4.0)

Overview

The SparkFun Simblee BLE Breakout board is a programmable board that allows you to add mobile app functionality via Bluetooth Low Energy (BLE, or Bluetooth 4.0) to your embedded projects. Unlike other BLE solutions, the Simblee requires no specialized app development skills to realize the phone-side interface: all the necessary coding is done in the Arduino environment and then uploaded to a browser app on the phone.

The Simblee RFD77101 module, equipped to this board, is intended to make embedded devices using Bluetooth Low Energy connections easier for everyone: hardware hackers, app developers, students, makers, engineers, and anyone else who wants to leverage their smartphone via BLE. For more information on using the Simblee to create your own applications for embedded project, visit our Simblee Concepts tutorial found in the Documents section below.

With the Sparkfun Simblee BLE Breakout you gain access to all the Simblee pins (with the module end compatible with RFDuino/Simblee shields!), as well as a reset button, an LED and a user accessible button. This is a great development board to stick in a breadboard and start playing with. It is also small enough to fit inside many projects. The voltage regulator is extremely low current, so your low power applications won’t suffer too much for it being included. While you can use the RFduino Programmer Board with this Breakout, we’ve provided a standard 6-pin FTDI breakout programming header as well. This allows the profile of the board to remain low unless necessary. We recommend using the either the LilyPad FTDI Basic or the 5V FTDI Basic for programming the Simblee Breakout.

Note : Please do not use the 3.3V FTDI Basic with this board, as it may not be able to source enough current from the 3.3V rail.

Works great for training dogs to walk with you
Size: Large, Color: Blue
I am a dog sitter and I like these for walking new dogs that I'm not familiar with. The dogs walk better with this type of leash rather than a harness.

Recommend for my pit mix.
Size: Large, Color: Blue, Size: Large, Color: Blue
Wasn't sure how this leash was going to be for my dog. He is a pit/border collie mix and I usually have a harness on him. No worries, he was great! Let's me put it on, responds to corrections and is much easier to handle. Why didn't I buy this earlier? Highly recommend.

Does help, but needs constant adjusting during walk
I watch so many Cesar television shows on how to correct dog behavior and see him use a Yellow version on the shows. I see there is not a yellow version of this lead available on the site so that was irritating because I wanted to get what he uses exactly from his show. Anyway, thanks to another reviewer, I knew to buy the "large" size of this for my 40lb dog because she made the mistake of buying the regular smaller size this site defaults to choose. The "large" is not very long, only 2 ft but maybe the rope is thicker. The rope is a light stretchy material so it does not chafe your hand, but it still burns after a while of your dog pulling and you trying to keep it from pulling. I could not imagine trying to use this on a dog bigger than 40 pounds because it feels like it is at it's max strength when I am dealing with mine. My dog likes to eat anything and everything on the ground as we walk so I needed this for the option of the muzzle control feature of the rope. As others have said it acts like the gentle leader halter. Pros: The adjustable slide to "secure" the loop size over your dog's head, behind it's ears is easy to move up and down. The black metal ring works well when you use the second circle to loop over your dog's muzzle. Every time she tries to open her mouth to eat something on the ground she can't. CONS: The adjustable slide to "secure" the loop is too easy to move and therefore I have to constantly push it back down on my dog's head while walking. I am trying to find a clamp of some sort I can clip behind this slider to keep it in place once my dog starts moving. As soon as it begins to slide up from movement, causing the neck hoop opening to widen and she is back to pulling hard.
