The Raspberry Pi is the single-board computer most of the projects on this wiki are built around. This page collects its GPIO pinout.

GPIO connector

RPi A+,B+ GPIO J8 40-pin pinout. [1] Models A and B have only the first 26 pins.

GPIO#	2nd fun	pin#	pin#	2nd fun	GPIO#
-	+3V3	1	2	+5V	-
GPIO2	SDA1 (I2C)	3	4	+5V	-
GPIO3	SCL1 (I2C)	5	6	GND	-
GPIO4	GCLK	7	8	TXD0 (UART)	GPIO14
-	GND	9	10	RXD0 (UART)	GPIO15
GPIO17	GEN0	11	12	GEN1	GPIO18
GPIO27	GEN2	13	14	GND	-
GPIO22	GEN3	15	16	GEN4	GPIO23
-	+3V3	17	18	GEN5	GPIO24
GPIO10	MOSI (SPI)	19	20	GND	-
GPIO9	MISO (SPI)	21	22	GEN6	GPIO25
GPIO11	SCLK (SPI)	23	24	CE0_N (SPI)	GPIO8
-	GND	25	26	CE1_N (SPI)	GPIO7
(Models A and B stop here)
EEPROM	ID_SD	27	28	ID_SC	EEPROM
GPIO5	-	29	30	GND	-
GPIO6	-	31	32	-	GPIO12
GPIO13	-	33	34	GND	-
GPIO19	-	35	36	-	GPIO16
GPIO26	-	37	38	-	GPIO20
-	GND	39	40	-	GPIO21

Model B rev 2 also has a pad P6 of 8 pins offering access to an additional 4 GPIO connections. [2]

Function	pin#	pin#	Function
+5V	1	2	+3V3
GPIO_GEN7	3	4	GPIO_GEN8
GPIO_GEN9	5	6	GPIO_GEN10
GND	7	8	GND

Models A and B provide GPIO access to the ACT status LED using GPIO 16. Models A+ and B+ provide GPIO access to the ACT status LED using GPIO 47, and the Power status LED using GPIO 35.
