The GPIO pins on the Raspi are arranged in a 2×13 header. Until Sparkfun manages to manufacture a decent Raspi protoboard, the easiest way to break these pins out is with an old IDE ribbon cable.

We took a quick look at the schematic for the board and see no reason for the ... 38 thoughts on “ Problems Powering Raspberry Pi From GPIO Header ” thantik says: September 4, 2012 at 11: ...

With this circuit you can plug in your battery though the connector and solder two wires: one from the 5v output pin on the PowerBoost to the Pi's 5v input (labeled on the GPIO diagram above), and ...

With Opto-pi, there is not an electrical connection between the Raspberry Pi and connected loads (motors, relay coils, etc.) or input signals. Opto-pi uses light to isolate the 8 digital GPIO pins.

The Raspberry Pi is a credit-card-sized single-board computer with a Broadcom BCM 2835 SoC, 256MB to 512MB of RAM, USB ports, GPIO pins, Ethernet, HDMI out, camera header and an SD card slot. The most ...
