How can i drive this 5v Relay board with RPi?
Here is a likely schematics of your relay module:



Relay to Raspberry connection:

VCC to +5V
IN+ to GPIO
IN- to GND
GND to GND


GPIO is configured as push/pull output, no pull-up, no pull-down. Relay is turned on by writing 1 to the port.

Alternate connection if the first one can't activate relay:

VCC to +5V
IN+ to +5V
IN- to GPIO
GND to GND


GPIO is configured as open-drain output, no pull-up, no pull-down. Relay is turned on by writing 0 to the port.

As voltage between IN+ and IN- is more then 2V, GPIO is never forced above 3.3V, so it should be pretty safe.
