Easy to configure and use
As others have mentioned, the silk screen printing for the relay connections is wrong. Normally open (N/O) is actually normally closed (N/C) and vice versa. Check the connections for yourself with a meter.The board is very easy to use, just follow the instructions. You do need some knowledge of programming a Raspberry Pi, but everything needed can be found on the internet.While there is a rating of 250 Volts for the relay contacts, the board is not safe for use with mains Voltages. Just be realistic and switch low Voltages, such as 12 Volts.It would have been a 5* review if the screen printing had been corrected.
