Nah, sorry. I keep running into design issues so I don’t have anything assembled. If it helps, The additional parts I need to buy/have bought are: adafruit proto hat for rasp pi. Some in-hole screw down terminals, and some different types of jumpers.
I figured I’d solder the hat to the gpio. Then solder on the 1k resistors. Then solder the screw terminals. Then from the terminals I’d attach them to the relay board like in the picture shown.
If I was to do this over again I’d probably buy 2-8 channel relays… Going with the 16 channel has ended up taking up too much time and money.
I think I got it figured out. After reading around it looks like you need to pull down each relay with a 1k resistor. So I ended up taking a jumper from gpio 18 (for example) and connecting a 1k resister to it. Then from the resistor I used another jumper and connected it to one of the pins on the relay board. Also I needed to set the Active State (I think that’s the setting) in OS to ‘low’.
