You need to know how to program a dashboard to see the value tho.

This is a REV Product. One thing of note, there are loads of pressure transducers of this type available on Amazon and Ebay, but in our opinion you get what you pay for. When we decided to offer this one to teams, we ordered and tested ones from about 10 different suppliers. The sensor drift, accuracy, build quality, etc were evaluated when we selected a supplier and the results varied greatly.

If you just want a pressure readout on your driver station you can probably get away with any of them as it is just a reference.

If you are trying to use it as a smart device to do extra logic on your robot; for example don't shoot until you have x pressure, or turning on an off your compressor based on current draw and setting your own hysteresis for compressor function, etc. The performance of the sensors matters quite a bit and we feel like we found one that was a good balance of performance and price. Additionally we will support it if you run into problems during implementation or failure.
