Part Number: LMP91000EVM

Hello,

Is the footprint for the gas sensor locations on the LMP91000EVM dimensioned anywhere?

Are the schematic and layout files available for this EVM?

These are the two gas sensor footprints we are considering.

Will both of these work with the LMP91000EVM?

Thanks,

Ken

Dear Ken -

Thanks for posting!

Regarding the sizing/layout of the pins -

I looked up one of the sensors the LMP91000EVM supports in the GUI.

From looking at this randomly selected parts' datasheet https://www.citytech.com/en-gb/PDF-Datasheets/4hyt.pdf the first drawing you posted is matched dimensionally, so it will fit on that board. The second one matched to this one, which was from the same family and is a "compact" sensor. https://www.citytech.com/en-gb/PDF-Datasheets/7hyt.pdf I think you should be good to go using those footprints, which I believe is "industry standard" for these types of sensors.

Josh, Thanks for the quick response. I just wanted to confirm before ordering sensors. Thanks again, Ken
