Hi,
i tried to install 2 nodes, node-red-contrib-ads1x15 and node-red-contrib-brads-i2c-nodes. Both failed with a long error list, attached at the end.
Both of them worked on Raspi 3. Now i made a image for my new Pi4 with all updates available.
Any instructions what to do? I'm not familiar with github as it is explained in another thread.

How did you install them ? via the gui or commandline ?

Hmmm, that node hasn't been updated in over two years and several people have had problems installing it (see [https://github.com/cinqueon/node-red-contrib-ads1x15/issues/7](https://github.com/cinqueon/node-red-contrib-ads1x15/issues/7))
you might want to see if there is another node you can use...

Thanks for the help!
