What’s going on cryptocurrency Universe — it’s The Bitcoin Miner here. This video is part 2 of my Orange Pi comparison series where I’m testing the cables, the CPUs, and the devices so you guys can get real numbers you can actually use. Today I’m mining the Verus protocol on the Orange Pi Zero 3 and looking at the big two: megahash produced versus watts consumed. And like I said in the first video, this info doesn’t just apply to SBC mining — you can apply the same mindset to phone farms and other low-power builds too. On the Orange Pi Zero 3, I’m seeing about 1.7–1.8 MH/s average with really solid temps around 44°C using a simple 15mm aluminum block heatsink with an adhesive thermal pad and a fan on top. Power draw is right around 2.8–2.9 watts with my “Mr glass” cable, and I show how a cheap cable can add about 0.2W — which becomes a big deal when you scale to 100 units. The takeaway: the Zero 3 is cheap (around $18–$21), but efficiency-wise it’s not competing with the better chip so far in this series. Stay tuned for part 3 where I test the Orange Pi 5 Plus.
