How we made the Harlo B30
The design, the BM1373 chip choice, and what the batches fund.

Official partnership
HeliumDeploy × Harlo Labs.
Harlo Labs builds home Bitcoin miners and the free operating system that runs them. We carry the full Harlo line — and Harlo OS ships free on every miner we sell, whatever the brand on the case.

Low power
Built for a wall socket.
The B30 runs about 30 TH/s on roughly 400W with the power supply built into the case. One C13 cable, no external brick, no dedicated circuit.
Harlo OS
The operating system is the product.
One free firmware that replaces what your miner shipped with: quad pools, Stratum V2, auto fan curves, wall-measured power and over-the-air updates. It runs on the whole catalog, not only on Harlo units.
Quiet
About as loud as talking.
Fan-and-heatsink cooling at roughly 50 dB, so a B30 can sit in an office or a spare room and stay there.
Back to this sexy looking OS.
My rejects are down significantly on my NerdQAxe++ and my Nexus L1.
