BM1373
The current chip generation.
The BS line runs the same BM1373 silicon as the 30 TH class units, which is where the efficiency at this size comes from.
Three sizes
95W to 300W.
BS-1 at 5.1 TH/s for a desk, BS-2 at 10 TH/s, BS-4 at 18 TH/s when you want real hashrate without a dedicated circuit.
Runs Harlo OS
Supported from day one.
Bitfortun support ships in Harlo OS, so a BS unit gets the same quad pools, fan curves and over-the-air updates as everything else here.
