Turtlebot3 Foxy SBC Setup Raspberry Pi 4

On Nov 24/20, a new version of the Turtlebot3 aManual was announced, that is an excellent resource for both ROS & ROS2. The 3.2 SBC Setup states its specifically for Raspberry Pi 3B+ using the Ubuntu 20.04.1 Preinstalled Server. (for RasPi). So my question is, that since an image for Raspberry Pi 4 64-bit is available (https://ubuntu.com/download/raspberry-pi), can you confirm that the eManual procedure following Ubuntu 20.04 installation steps in 3.2. Step 3.2.5 to install ROS Foxy will work? Can you give an ETA for a new updated eManual?

Hi @red24dog,
You can apply the eManual instructions for Raspberry Pi 4 with the correct Ubuntu image for your RPi 4.
When I tested with my RPi4 2GB, the installation process wasn’t much different from that of RPi 3B+.
RPi 4 instruction will be officially available by the second quarter of 2021 at the latest.
Thank you.

Yea! That is next month . Someone must look like a one armed paper hanger in a windstorm. :joy:

OH My this may help a littlt bit, there is a new ubuntu ros desktop out for the rpi4. Shows support for pi4!

A caution is that this Raspberry Pi image is 20.10 LTE, expiring July 2021. So might be advisable to install the LTE 20.04 and manually install LXDE Desktop.

@Lloyd As far as I tested, Ubuntu 20.04 showed unstable wifi connection with RPi4. It won’t connect to 5G wifi in my lab. Still investigating what the problem is.
@red24dog You’re right, it is recommended to use LTS version as we cannot support every OS versions.
