Hallo,

   

does anybody knows how much current over 3.3V can be supplied to the user modules connected either to PORT A, B or C?

   

I'm going do develop a module and I wish to know if I had to provide an external power supply. My module is expected to sunk about 150-200mA over 3.3v.

   

Best Regards,

Hello Michelle,

   

There is no CY9CKIT-001. Is this the question for the CY8CKIT-001? Please confirm.

Of course it's the CY8CKIT-001.

    If you configure expansion ports as GPIO, you have 8 mA sink and 4 mA source current.   
   
    If you configure expansion ports as SIO, you have 25 mA sink and 4 mA source current.

I supposed that the VIN pin in the schematics of the PORT A, PORT B, PORT C was a power supply line. But from your answer I'm not sure of this anymore also because I have dind't found the VIN label in any other place in the schematics so it's not apparently connected to any power supply line. Of course since I have have to build an external board with a 300mA power rating I think it's better for me to put an external power supply.
