Adding BMP580 to AirGradient ONE v9: IO1 Connector and Firmware Support

Hardware extensions
#1

Hello AirGradient folks,

I’m trying to add a BMP580 as an extension to my AirGradient ONE I-9PSL-DE PCB Version 9+. I bought the BMP580 breakout, DigiKey 1528-4424-ND, but then realized I don’t have an obvious solderless way to connect it to the board.

I then tried an Amazon GH1.25 8-pin cable for IO1, because I’m avoiding soldering unless I want to include “burning down the house” as part of the project. Unfortunately, that connector is just slightly too large and does not fit.

So I’m back to square one:

  • Is IO1 a valid place to connect an I2C sensor like the BMP580?
  • If yes, what exact connector/cable fits IO1?
  • Are I2C1 / I2C2 the preferred ports, and do they require soldering a header/socket?
  • If I get the BMP580 connected, does the current firmware support reading it?
  • I’d also like to daisy-chain a VEML7700 from the BMP580 afterward.

Any guidance on the correct connector and firmware support would be much appreciated.
