OSMU

The OSMU (Open Source Mining Unit) is a compact, open-source ASIC controller board designed for home miners who want full control over their mining hardware. D-Central Technologies stocks the OSMU alongside compatible accessories, heatsinks, and power solutions — everything you need to build and run these versatile mining controllers.

OSMU boards bridge the gap between tiny solo miners like the Bitaxe and full-scale ASIC machines. They support multiple ASIC chip configurations, giving you flexibility to scale your home mining setup at your own pace. Open-source firmware means no vendor lock-in — inspect the code, modify it, contribute to it.

Our OSMU collection includes:

OSMU controller boards — Ready-to-run units with pre-installed firmware
Heatsinks and cooling — Thermal solutions sized for OSMU form factors
Power cables and adapters — XT30, DC barrel, and custom power delivery options
Stands and enclosures — 3D-printed mounts designed for optimal airflow
