Re: Rasp Pi - What do I need?

Either a 4 or a 5 will suit your needs. Vilros has both models available. Be sure to purchase the correct power supply with the model you purchase as it will have the correct amperage. Prices are within $20 of each other.
Both models have 40 GPIO pins. Some contain voltage and some are grounds which you will not be utilizing for io operations.?
When considering a case, ensure you can freely attach any cables or wires. Some fan cases will block a ribbon cable. ?
Once you go production you may want to consider a second Pi and supply to sandbox (test machine) any new hardware or software.
Reference theWiki to get you started and creating your first image. Backup SD cards are your friend.

Hi All,
I'm moving my Node RED flows for TGXL control from Windows to a Rasp Pi. I have never owned or used a Pi and know just the basics. In addition to the Pi, I need a minimum of a 10 pin GPIO.
?
Can anyone offer guidance on just how much capability and capacity I need in this Pi? Pi 4 or 5? Ram? Cases? Kit?
?
Any and all help appreciated.
?
Thanks and 73,
