SparkFun SparkFun RedBoard - Programmed with ArduinoAt SparkFun we use many Arduinos and were always looking for the simplest, most stable one. Each board is a bit different and no one board has everything we want, so we decided to make our own version that combines all our favorite features. The SparkFun RedBoard combines the simplicity of the UNOs Optiboot bootloader (which is used in the Pro series), the stability of the FTDI (which we all missed after the Duemilanove was discontinued) and the R3

At SparkFun we use many Arduinos and we’re always looking for the simplest, most stable one. Each board is a bit different and no one board has everything we want, so we decided to make our own version that combines all our favorite features. The SparkFun RedBoard combines the simplicity of the UNO’s Optiboot bootloader (which is used in the Pro series), the stability of the FTDI (which we all missed after the Duemilanove was discontinued) and the R3 shield compatibility of the latest Arduino UNO R3.

The RedBoard can be programmed over a USB Mini-B cable using the Arduino IDE: Just plug in the board, select “Arduino UNO” from the board menu and you’re ready to upload code. RedBoard has all of the hardware peripherals you know and love: 14 Digital I/O pins with 6 PWM pins, 6 Analog Inputs, UART, SPI and external interrupts. We’ve also broken out the SDA, SCL and IOREF pins that showed up on the UNO R3, so the RedBoard will be compatible with future shields. This version adds an SMD ISP header for use with shields.

You can power the RedBoard over USB or through the barrel jack. The on-board power regulator can handle anything from 7 to 15VDC. Check out the related items below for a compatible wall-wart power supply.

On the thin side....
Color: White, Size: King (Pack of 2)
These are described as "high loft" and "supportive", but they are fairly thin/flat and very soft.

Great Support; not too Soft.
Color: White, Size: Standard (Pack of 2)
These are extremely comfortable pillows. I bought them for my every-night use, and they have not disappointed me. They provide great support for one’s head. They mold around one’s neck foot just turn perfect amount of support without being extremely soft. They hold their original manufactured shape easily.

Luxury pillows
Color: White, Size: King(2Pack)
I purchased these pillows to be used as sham fillers, however, the pillows are so great I am now using them for sleeping. The filling conforms to your sleeping position and provides a comfortable sleep. They come rolled in plastic and are paper thin. Once removed, they fluff up beautifully and very evenly. These pillows are high quality and a good value for the price. Highly recommend.

Perfect for Decorative Shams!
Color: White, Size: King(2Pack)
I purchased the VAINOC king size pillows specifically to use inside decorative shams, and they are absolutely perfect for that purpose. They have just the right amount of firmness to keep the shams looking full and well-shaped without being overly stiff. I love how they instantly made my bed look more polished and put-together. The size fits beautifully in king shams, giving that plush, high-end look you usually see in hotels or magazines. The quality is great for the price, and they fluff up nicely without going flat. If you’re looking for affordable pillows to elevate your bedding decor, these are a great choice!
