Expansion connector i/0

Hi,

Does someone has any circuit design for interfacing a relay to an i/o ? I have the flat cable and the mini i/o connecter.

I know that these i/o have a maximum current of 1 ma if I read it correctly.

Regards,

Mario

There are many breakout boards with the ULN2803 driver IC which can drive LED arrays, motors, and relays up to 500mA
