I received the PCB and wrote the code for it, first results are promising.
First results:
The PCB with the components already soldered costed me around 5€
I can detect variations of 1Pa and overtime I get a drift of 10Pa which is not bad as it means that reading above 4m/s 15km/h should be accurate and get more accurate as speed increase
I programmed the board to read data from the baros and calibrate them using the push button
I managed to send the results to INAV using MSP and seeing them via the INAV configurator
