Display connector I2C and GPIO


There are two I2C ports on the display connector, I2C_GP0 and I2C_GP1.
Can I use any of these I2C ports? Am I right to assume I2C_GP0 is 1V8 and I2C_GP1 is 3V3?

Also, I have an IRQ pin from my board that I wish to connect to the TX1 board, is there a pin on the display connector that I could use for that?

Finally, there’s no problem using the VDD_1V8 and VDD_3V3_SYS to power my device, right?

Thanks a lot.

Yes, on display connector, GP0 is 1v8 and GP1 is 3v3, you can use them as you wish.

NVSR_INT (pin 98) could be used as IRQ.

No problem to use VDD_1V8 and VDD_3V3_SYS to power your device.

Thank you.
