GPIO voltage levels are 3.3 V and are not 5 V tolerant. The first 26 pins are the same as P1 on the A/B boards, with the remaining 14 pins providing additional GPIO and ground pins, and an EEPROM ID feature for auto-configuration with add-on "HAT" boards. The Raspberry Pi Model A+ and B+ boards, and the Pi 2 Model B, have a 40-pin header marked J8, arranged as 2x20 pins.

Momentarily shorting the two pins of P6 together will cause a soft reset of the CPU (which can also 'wake' the Pi from halt/shutdown state). The P6 header was added with the release of the Revision 2.0 PCB design.Ī reset button can be attached to the P6 header. Note that the connector is placed JUST off-grid with respect to the P1 connector. The new header can provide a second I☬ channel (SDA + SCL) and handshake lines for the existing UART (TxD and RxD), or it can be used for an I2S (audio codec chip) interface using the PCM signals CLK, FS (Frame Sync), Din and Dout. Pin 1 and pin 2 are swapped, pin 3 and 4, etc.Īn alternative way to attach this header is on top, at a slant away from the P1 header. Note that the connector is intended to be mounted on the bottom of the PCB, so that for those who put the connector on the top side, the pin numbers are mirrored. The P5 header was added with the release of the Revision 2.0 PCB design.ĪLT2 = PCM_DIN ALT3 = UART0_CTS ALT5 = UART1_CTSĪLT2 = PCM_DOUT ALT3 = UART0_RTS ALT5 = UART1_RTS The P3 header, unpopulated, is the LAN9512 JTAG.

The P2 header is the VideoCore JTAG and used only during the production of the board. See this discussion for more details of the changes between Rev 1 and Rev 2 PCBs. Revision 1 PCBs also do not have the P5 header (see below). Revision 1 PCBs: Raspberry Pis with a revision 1 PCB (September 2012 or earlier) have a different pin assignment on the P1 connector: Pin one is the pin in the first column and on the bottom row.

They provide 8 GPIO pins plus access to I☬, SPI, UART), as well as +3.3 V, +5 V and GND supply lines. The Raspberry Pi Model A and B boards have a 26-pin 2.54 mm (100 mil) expansion header, marked as P1, arranged in a 2x13 strip. General Purpose Input/Output (GPIO) Model A and B (Original) P1 Header. Sample circuits for interfacing the GPIOs with other electronics are shown on the RPi GPIO Interface Circuits page.To connect devices to the serial port (UART), see the RPi Serial Connection page.

However, add-on boards such as the Rpi Gertboard provide this capability. Note that no analogue input or output is available. The Raspberry PI GPIOs use 3.3V logic levels, and can be damaged if connected directly to 5V levels (as found in many older digital systems) without level-conversion circuitry. Unlike USB, etc., these interfaces are not "plug and play" and require care to avoid miswiring. Communication with chips or modules using low-level protocols: SPI, I☬, or serial UARTĬonnections are made using GPIO ( "General Purpose Input/Output") pins.Digital inputs: read an on or off state from a button, switch, or other sensor.Digital outputs: turn lights, motors, or other devices on or off.In addition to the familiar USB, Ethernet and HDMI ports, the Raspberry Pi offers the ability to connect directly to a variety of electronic devices. Other Peripherals - all sorts of peripherals used with the Raspberry Pi. Screens - attaching a screen to the Raspberry Pi.Ĭases - lots of nice cases to protect the Raspberry Pi.
