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


Colour legend
+5V
+3.3V
Do not connect
UART

I2C

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"?
