I have a working system to measure the fuel pressure on my truck using this transducer and a Raspberry Pi Pico W. The transducer is soldered to the Pico. It sends its data over wifi to a Raspberry Pi 4 also in the truck. I’d like to go to a completely wired solution. The problem is that the transducer above requires 5V and QWIIC is only 3.3V. I’ve looked for a QWIIC board with a transducer suitable for a fuel system and can’t seem to find one. They all seem designed to measure air pressure. I need something that has 0% chance of leaking fuel or ingesting air.
I am not clear about one thing. Why QWIIC is necessary here?
If Qwiic is needed as asked earlier post, look at the SparkFun Qwiic 5V Boost - AP3012K - SparkFun Electronics. That will provide 5V to a device and bridge to 3v3 I2C
The wifi solution I have now works most of the time. When it doesn’t I don’t notice it right away and when I go to look at the live value its sometimes non-existent or displaying old values. With QWIIC there’s nothing to wait on or any question about whether or not its sending data.
Thank you. That might be what I need.
