I2C device on S32K3-T-BOX

[jared112]

Hello, I was planning to connect a few of these F9R GPS breakout boards via I2C to the S32K3-T-Box development board but I'm not sure if it'll work. I was going through the documentation and found out that the J44 pins (I2C) are for external audio amplifier for AVB application. I want to make sure before making a purchase on this board. Any help will be greatly appreciated, thank you!

I see. I was planning on using that and a few other boards but they're all out of stock. In this case, I think I will go with the S32K148EVB. Thank you!!

Hello @jared112,

Other devices can be connected to the I2C bus, but the bus is already used by these 3 devices on the board:

U13 SGTL5000XNBA3,

U11 CDCE6214TWRGERQ1,

U10 CS2100CP-CZZ

Do you need the T-BOX? Maybe the general purpose S32K344 EVB can be a better choice:
