Hi Charles, the IRQ (DRDY pin) of Max31865 need to be wired?
I can presume that it can be useful to trigger an interrupt when a conversion is completed, but it is not mandatory. Can i left it unconnected ?

Hi CHARLES,
Can you give me information (specs) about the SMD FB1 and FB2 ?
There is a Mouser or Digikey part number for this item?
Thanks
