I already tried to connect the VCC to 3.3v but didn't workThe referenced pdf file shows the schema of the board.
Compare with the schema in viewtopic.php?f=91&t=83372&p=1225448#p1225448
Do not use the jumper shown in the image on J5. Connecting relay board VCC to 3.3V is correct, but possibly the board will not work as described in the other forum entry.
Tomorrow I will try the wiring diagram that ame suggested
