This is a four wire cable assembly to one end with a 4 pin JST SH connection.
10-pin socket with 2mm pitch that mates with the popular XBee radio from Digi.
This USB breadboard power supply kit provides power source from any USB port and outputs a fuse protected and regulated 3.3V. The .1" headers are mounted on the bottom of the PCB for simple insertion into a breadboard. Pins labeled 5V/GND 3.3V/GND plug directly into the power lines.
This can equip your Arduino with mass-storage capability, so you can use it for data-logging or other related projects. All new microSD shields have a voltage converter chip on-board that converts the Arduino 5V signals to 3.3V signals in accordance with SD specifications.
This is a breakout board made for 28 pins SOIC style. These are custom PCB boards that interface standard SOIC devices to standard .1" headers. Standard .6" spacing between pins. Will fit directly into a standard width (600 mil) DIP socket. For wide ICs (memories, drivers, 74s, etc).
