What do you buy Orange Pi for?

I saw somebody selling two second hand Orange pi one for 11usd yesturday. Without much thinking, I bought it. But now I’m wondering what can I do with them. I have a Raspberry Pi 4B before, it was for desktoping, however this SBC seem to be much weaker. Do you guys have any advice on how can I do on these two SBC?

Below is the spec of Orange pi one CPU:H3 Quad-core Cortex-A7 1.2Ghz GPU: Mali400MP2 GPU @600MHz Memory :512MB DDR3
