FireBeetle ESP8266 IOT Microcontroller
Overview
DFRobot FireBeetle is a series of low-power-consumption development hardware designed for Internet of Things (IoT). Firebeetle ESP8266 is a development board integrated with IoT WiFi, TCP/IP, 32-bit MCU, 10-bit ADC, and multiple interfaces such as HSPI, UART, PWM, I2C, and I2S. In DTIM10, the full power consumption to maintain a WiFi connection reached 1.2mW. Equipped with 16MB outer SPI flash memory, ESP8266 is available for programs and firmware storage.
Compatible with Arduino programming enables Firebeetle ESP8266 to lower the barrier of programming. The operator can implement Arduino programming codes directly onto ESP8266 to reduce the difficulty of operating and increase the stability of the esp8266 board.

High quality, wish it was just a little smaller
Style: Squeaker, Size: Small (2 Pack)
Love these. My dogs would play ball all day if I let them. These are very durable and bouncy. Love that it’s washable. They would chew up the small “tennis” balls to pieces so I love that they can’t destroy these. My only criticism is I wish these were just a little smaller (like the size of the small Kong tennis balls). My dogs can carry it in their tiny mouths but they can’t get their mouth around it enough to chew it to get the squeaker to squeak, which is their favorite thing.

The perfect ball for a small to medium dog.
Style: Ultra, Size: Small (2 Pack)
My dog's favorite ball. Perfect size for playing catch and return for a small dog. She loves to chew on the ball. Very durable she has not been able to shred the ball.
A great entertainment value. This ball does not squeak.

Great
Size: Medium, Number of Items: 1
I need something that was soft for my three year old and this ball is super great, it not only is the right size but it also fits in his mouth just right. Although he is a super aggressive chewer, the ball toy hasn't been totally destroyed yet and it is easy on his gums. The ball is so durable that got two of these toys just for fun.
