Out of the blue I tried again from home and it seemed to have worked...

I'm trying to use pip3 to install boto3 to my omega2+ however I'm getting the following install error from pip3 when trying to install the package.

I have installed python3-light package no problems. Other packages I needed so far have installed no problem just seem to be hitting a roadblock with getting boto3 to install. Has anyone got boto3 to work on their omega2?

[code]
pip3 install boto3

@Callum-Stew How much space does it free up if you remember?

@Gerhard-Bertelsmann Just using a cheap usb to rs232/ttl adaptor I think I got like 10 or so off ebay for like $10~15 a year or so ago. So far seems to work fine on omega2+.

@Douglas-Kryder Thanks i'll look into it, I did read something about it but thought it was just for the 2+ model as it came with a sd card slot.

@Fabian-Nydegger

What omega did you use? If you implement this on Omega2 I’d be interested as everything I tried to get rs485/232 TTL support for the omega2 I ran out of space on the device...

I was however able to install python3-light, python3-pip and MinimalModbus on my omega2+ no problem. Omega2 doesn’t even have enough space to install both python3-light and python3-pip

Just came here to see if anyone else was running our of room on the omega2 just by putting python-light on it and getting bumped when trying to add pip... I also tried python-base but needed to add to many dependencies for my application and even tried the setup.py from the package but it also required too many dependent packages so that also fell over and due to space required for other dependencies argh! I think the omega2 will find its useful place in the trash can tbh.

omega2+ however so far works well because of the extra space.
