The device is OK and as expected. I'm a little disappointed that there are no pull-up resistors on GPIOs 5 and 6, meaning that relays 1 and 2 are on by default when the Pi is powered on. Considering how cheap resistors are I'm sad to see that this is just a copy and paste job and that two such simple components could just be left out and forgotten. I think I have to have an unfortunate operation. on board to disable GPIO5 and 6 during boot.
