OpenCR firmware for ROS2 compatible with discontinued accelerometer

My Turtlebot3 is from 2017, so would have the accelerometer.
I am switching to ROS2 Foxy, and am wondering if the new firmware for ROS2 is compatible with my older hardware?
Or is my old firmware compatible with ROS2?
Thanks

Hello @Meldor thanks for your question! It brings up a good question regarding the OpenCR1.0 firmware. Unfortunately the firmware / ROS details are not my area of expertise, but I think @willson or @Yogurt_Man should be able to provide more information.

As it’s related to the updated resources for ROS, there may also be some related content at https://answers.ros.org/questions/

Hi @Meldor
The IMU will be automatically selected by the IMU driver in OpenCR library as shown below.
Thank you.

Thank you. That answers my question, and gives me the url for where the turtlebot stuff is in Github. I just downloaded the ROS programming book, and am starting to read about editing the OpenCR.
Thanks!
