Bitaxe Supra 400-series entity boundary

The dedicated schematic/BOM identifies BM1368; stale repository prose mentioning BM1366 is not used.

This is an open board design licensed under CERN-OHL-S-2.0, not one fixed retail appliance. Multiple assemblers may use different heatsinks, fans, enclosures, displays, adapters, clocks and voltages. Generic retail ProductModel, fixed-SKU comparison and profitability are therefore withheld.

Supra DC and cooling contract

5 V DC only, adapter above 15 W, 5.5 × 2.5 mm center-positive barrel. Active cooling with a 5 V 40 mm fan is mandatory.

AxeOS/ESP-Miner firmware safety

Firmware and factory images must match device-reported board, family, ASIC, ASIC count and hardware revision. Unified releases do not authorize a generic cross-flash; Hex variants may use different maintainer forks. Recovery can leave an incompatible old web partition, so exact release assets and rollback steps are required.

Performance is configurable and autotuned. Voltage/frequency unlocks can damage inadequately cooled hardware. Absolute dBA, assembly dimensions, mass, earnings and “lottery” success are not board-global specifications.
