This is the **Pro** version of the HobbyTronic Raspberry Pi breakout board which allows you to break out all the power, GPIO, I2C and SPI pins from the 26 pin Raspberry Pi header onto a solderless breadboard.
The **Pro** Version includes:
3.3V 500mA voltage regulator
LED power indicator.
The Raspberry Pi already has a 3.3V output so why the voltage regulator? Well the Raspberry Pi uses quite a lot of the onboard regulator's power output leaving very little for anything you may want to connect up that requires a 3.3V supply. So now you have 500mA at your disposal without affecting the Raspberry Pi's power!
Supplied in kit form, it includes the following
GPIO Breakout Board PCB with surface mount components pre-soldered.
2 x 13 way header pins
26 way IDC box header.
Soldering is required to assemble the kit
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
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:
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.
