MiCS-5914: Pin Assignment concerns

Hello, while reviewing the datasheet for the MiCS-5914, I noticed that only four pins (C, D, F, G) have clear connection instructions, while the others are not specified. I’d like to ask how I should connect the other pins if I’m to use this sensor. Should they be grounded or left unconnected?

Hello hduan5, welcome to the DigiKey TechForum.
The other pads do not have any internal connections. You can leave them unconnected, or solder them to the board, for added security. The more solder points on the board, the more stable it will be.
