Raspberry Pi GPIO Breakout Board

This useful Raspberry Pi GPIO breakout board allows you to break out all the power, GPIO, I2C and SPI pins from the 26 pin Raspberry Pi header onto a solderless breadboard.

Supplied in kit form, it includes the following

• GPIO Breakout Board PCB
• 2 x 13 way header pins
• 26 way IDC box header.

Soldering is required to assemble the kit

It does not include the GPIO cable, which is available separately in either 6 inch or 12 inch length.

• Breaks out the 26 way GPIO pins onto breadboard
• Includes separate 5V, 3V, 0V, SDA, SCL header on side of board for connecting to I2C devices

Raspberry Pi changes for Revision 2 Boards

Rapsberry Pi have made some changes to the port connections on the header socket for the latest Revision 2 boards. If you have a Revision 2 board (Easily identified by the two mounting holes on the board) then the following changes effect you

See the full details on our GPIO Pinout page

JTAG Debug Support

Two GPIO pins have been interchanged to allow a missing debug signal (ARM_TMS) to appear on P1 pin 13.

Originally the connections were:

• CAM_GPIO [BCM2835/GPIO27] routed to S5 pin 11
• GPIO_GEN2 [BCM2835/GPIO21] routed to P1 pin 13

The new connections are:

• CAM_GPIO [BCM2835/GPIO21] routed to S5 pin 11
• GPIO_GEN2 [BCM2835/GPIO27] routed to P1 pin 13

I2C Support on P1/P6

The primary and secondary I2C channels have been reversed.

Originally the connections were:

• SCL0 [BCM2835/GPIO1] routed to P1 pin 5
• SDA0 [BCM2835/GPIO0] routed to P1 pin 3
• SCL1 [BCM2835/GPIO3] routed to S5 pin 13
• SDA1 [BCM2835/GPIO2] routed to S5 pin 14

The new connections are:

• SCL0 [BCM2835/GPIO1] routed to S5 pin 13
• SDA0 [BCM2835/GPIO0] routed to S5 pin 14
• SCL1 [BCM2835/GPIO3] routed to P1 pin 5
• SDA1 [BCM2835/GPIO2] routed to P1 pin 3
