Prototyping with a Raspberry Pi B+ is a lot easier with the Pi Wedge B+ by Sparkfun. The small, T-shaped board comes as a kit. Once built, it connects to the 40-pin GPIO connector on the Raspberry Pi B+, and breaks out the pins so that they can be easily attached to a standard, solderless breadboard.
The Pi Wedge B+ also comes with a few decoupling capacitors for the power supply lines. Prototypers can also plug an FTDI Basic module into the built-in serial port.
The Pi Wedge B+ can be purchased from Sparkfun’s Website for $7.95.
