Save old header pinout table
Header Pinout:
Top Row | 5V0 | DNC | GND | UART0_TXD | UART0_RXD | GPIO1_PWM | DNC | GPIO4 | GPIO5 | DNC | GPIO6 | SPI_CE0_N | SPI_CE1_N |
Bottom Row | 3V3 | I2C0_SDA | I2C0_SCL | GPIO7 | DNC | GPIO0 | GPIO2 | GPIO3 | DNC | SPI_MOSI | SPI_MISO | SPI_SCLK | DNC |

Donster2k: "Kernel boot messages go to the UART at 115200bps." - This should be configurable as a kernel parameter. It is the bootloader that will always output to the uart on the header, correct?
Donster2k: What will be the power-on states of the GPIO pins?
Donster2k: USB2 spec states that the max current draw from a port (either powered hub or PC's usb) is 500mA. Does this mean that the revB module will need to be powered via a usb charger?
Donster2k: Most of the reference links to the forum are broken. Probably happened when they moved the forum.
naicheben: The color legend is fine for the table "Header Pinout" but it does not correspond to the GPIOs.gif as stated below the GIF. Shouldn't we better use same color "coding"?
