Installing RTC on patchbox

Hi!
I’m trying to install an RTC chip on a Raspberry Pi 3 A+ running Patchbox OS.

I’m following the instructions here: https://learn.adafruit.com/adding-a-real-time-clock-to-raspberry-pi/set-rtc-time

I’m using a slightly different RTC chip, but I think it should work the same.

In any case, when I run sudo i2cdetect -y 1 I get the following error:

Error: Could not open file `/dev/i2c-1' or `/dev/i2c/1': No such file or directory

I’m not very knowledgeable on this, am I going about it wrong? Or does this work differently on Patchbox then it would on other Pi OS’s?

ah, never mind I think I’ve figured it out (or at least gotten past that error) - I just needed to sudo raspi-config and enable I2C in the interfacing menu.
