SparkFun SparkFun ESP8266 Thing - Dev Board (with Headers)This is the SparkFun ESP8266 Thing Dev Board a development board that has been solely designed around the ESP8266, with an integrated FTDI USB to Serial chip. The ESP8266 is a cost effective and very capable WiFi enabled microcontroller. Like any microcontroller, it can be programmed to blink LEDs, trigger relays, monitor sensors or automate coffee makers.

This is the SparkFun ESP8266 Thing Dev Board — a development board that has been solely designed around the ESP8266, with an integrated FTDI USB-to-Serial chip. The ESP8266 is a cost-effective and very capable WiFi-enabled microcontroller. Like any microcontroller, it can be programmed to blink LEDs, trigger relays, monitor sensors or automate coffee makers. With an integrated WiFi controller, the ESP8266 is a one-stop shop for almost any internet-connected project. To top it all off, the ESP8266 is incredibly easy to use; firmware can be developed in Arduino and uploaded over a simple serial interface. The ESP8266 Thing Development Board breaks out all of the module�s pins with pre-soldered headers, and the USB-to-serial converter means you don�t need any peripheral components to program the chip. Just plug in a USB cable, download the Arduino board definitions, and start IoT-ing.

Why the name? We lovingly call it the �Thing� due to it being the perfect foundation for your Internet of Things (IoT) project. The Thing does everything from turning on an LED to posting data with phant.io, and can be programmed just like any microcontroller. You can even program the Thing through the Arduino IDE by installing the ESP8266 Arduino add-on.

The ESP8266 Thing Development Board is a relatively simple board. The pins are broken out to two parallel, breadboard-compatible rows. The USB connector sits next to an optional power supply input, and an ON/OFF switch — controlling power to the ESP8266 — sits next to that. And LEDs toward the inside of the board indicate power, charge and status of the IC. The ESP8266�s maximum voltage is 3.6V, so the Thing has an onboard 3.3V regulator to deliver a safe, consistent voltage to the IC. That means the ESP8266�s I/O pins also run at 3.3V; you�ll need to level shift any 5V signals running into the IC. If your project requires a power source other than USB, the Thing Dev Board includes footprints for a 2-pin JST, 2-pin 3.5mm screw terminal, or a simple 0.1"-pitch 2-pin header. Unlike the original ESP8266 Thing, the ESP8266 Thing Dev Board does not have a built-in LiPo charger.

The Thing Dev Board even includes a PCB trace antenna as a default WiFi antenna. It�s cost-effective and works really well! If you need to connect a more sensitive antenna, or need to route outside an enclosure, a U.FL connector is also available on the board. Some soldering will be required to get the U.FL connector functioning, but instructions can be found in the Hookup Guide we have written for the dev board.

Note: We’ve provided a few Example Sketches to experiment with on your SparkFun ESP8266 Thing Development Board. These sketches can be found in the Hookup Guide in the Documents section below!

My dog LOVES these !!!! And he’s very picky !
Flavor Name: Chicken
Omg !! My dog is the Pickiest dog on planet EARTH ! He hates every snack treat I have bought for him and I wind up giving all the treats and vitamin supplements to the neighbor down the street who has a dog !!! But he absolutely LOVES these like CRAZY !! And I try to limit him to only a few per day ! But he gives me those puppy eyes, and stands up on his hind legs begging me for 1 more and I always wind up giving in to him !! Boy! He can’t live without these , and I make sure that I never run OUT !!! It’s plain chicken which he’s crazy about , he doesn’t like beef treats at all , so these are excellent for the price point and must be very tasty because he loves them totally !!! It’s a nice long cut stem of chicken , but he devours it quickly , and it comes with a stay fresh packet inside the bag ! But these never last because he eats them up quickly ! The price is very good for the quantity that you get inside the bag ! My dog just loves these !!

Healthy treats
Flavor Name: Chicken, Flavor Name: Chicken
This Chicken Jerky is amazing. You can literally break up the chicken with your hands. I am cautious about what I give my dog but it is the real deal. My Chihuahua LOVES it and he is super picky. Even the price is reasonable and it is a healthy treat.

My dog won't touch anything else
Flavor Name: Chicken
Suffice it to say I have full bags of other chicken jerky treats. They're open. They're also full. She won't touch anything else. She loves Pawmate and Pawmate only.

Origin of product
Flavor Name: Chicken
I ordered these for my 12year old pup a few months ago and continued ordering bc he loves them. I may have reviewed these treats in the past…I cut them into small pieces to last a little longer as they are expensive. They always smell like as I think they should. However, I finally took some time to read the ingredients and saw that these are radiation treated, which supposedly is safe, but questionable if it’s from China. Now I’m hesitant to order them again. I admit he seems fine after eating them but I’m afraid what could happen in the long run. Just my thoughts.
