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.

Don't buy the other brands
Color: 2-Pack Black
I'd give these a 10 if I could. I bought another version but returned ii because I didn't think it was very sturdy. These were only $8 more and what a difference. They are a very well made and a lot more sturdy. The extra $8 was a real bargain and well worth it.

Great for short people to see and retrieve spices from upper shelf! Holds a lot of weight easily!
Color: 2-Pack Black
These spice racks were very easy to install in my cabinets. Actually, I have only used the adhesive, and they are holding all of the weight of the spices without any issue! These are remarkably heavy duty. I am short (5"3") and most of the second shelf is not really very useable without a stool. I can pull these out and turn the racks making all of them visible and easy to reach! I have two and I'm seriously considering ordering more! It makes organizing a breeze too!

Beautiful, easy assembly.
Color: 2-Pack Black
Looks great, easy to assemble. Just a little narrow, wish I would have ordered a little bit bigger size.
