Maximum DC current for GPIO pins and power lines?

Hi,

1) What is maximum load DC Current for GPIO I/O and 5V / 3.3V pins on expansion header?

2) Logic level for GPIO / SPI is 3.3 V right?

    Anybody have informations about maximum load current for GPIO / power lines?

    Hi,
    logic level are 3V3-TTL for all GPIO

    GPIO are driven by Altera MAX V CPLD and GPIO output current (IOH/IOL) for 3V3-TTL is 16mA per PIN with a Max absolute rating of 25mA (Table 2-7 Altera doc: https://www.altera.com/en_US/pdfs/literature/hb/max-v/max5_handbook.pdf)

    I can't find any information about maximum current ratings for 5V and 3.3V power pins. It should be stated in the wiki but isn't:
    https://wiki.up-community.org/Pinout

    Could you please provide this information? It's important to know how much current can be drawn to power external sensors or cooling fan for example.

    hi. it is also will be very helpful to know is usb3.0 actually can provide 2A to power devices with provided power supply.
    and what is maximum amperage on a camera and display power pins.
