Waveshare Raspberry Pi 8-ch Relay Expansion Board, let your Pi able to control high voltage products

good morning please i need some and a supplying in Ghana

I wish someone would do a more in depth look at this board and it’s features.

Hi, can i use it to control Sensors via SPI?

I used NodeRED's standard RPI I/O library to control the relais. Very easy implemented.

Is there an stl file for a case for this?

All the software examples only show how to drive 3 relays, not all 8 of them.
