What to bring to Cuba as a small IT-gift as a tourist?

Hi,

After a month I'm going to have a vacansion in Cuba. I have heard, that the country has shorage of electronics due to sanctions.

I have a few old, but working, wifi-routers (with openwrt, I think), which I do not use any longer. Is there any sense to bring them here and give to people, do they have such a need? Or this also electronic garbage, and just throw it away?
