The board itself is tiny, at around 25mm x 20mm x 9mm. It also weighs just over 3g, making it perfect for mobile or other applications where size and weight are important
The USB 2.0 Extension Cable extend the distance between your USB peripheral and your USB hub or computer assure good signal quality to meet USB specification.
Separated pin plugs, this cable is ideal for powering and connecting up to the debug/login console on the Raspberry Pi or BeagleBone Black. Connect the pins as shown to power the Pi or BBB and establish the RX/TX link.
The connector heads measure 0.51" x 0.36" x 0.25" (13.0 x 9.3 x 6.3 mm) on the USB micro B end and 0.51" x 0.55" x 0.25" (13.0 x 13.8 x 6.3 mm) on the USB A end.
Raspberry Pi® computer you just got has a row of 2x13 pin headers soldered on - those are the GPIO (general purpose input/output) pins and for those of us who like to hack electronics they are where the real fun is. By programming the Pi, you can twiddle those pins high or low, send and receive I2C and SPI data, and access the 3V and 5V power rails.
Make your Pi a little slimmer with this microSD card adapter board. It slides in where the SD card goes but is half the length. Pop in a microSD card for a sleeker machine. The microSD card holder is a push-push type so you can push on the edge that sticks out to remove the card when necessary.
