Published PCB files, bill of materials, and interface, for anyone to build on.
Ember One is an open-source reference design for a Bitcoin mining hashboard. A hashboard is the circuit board that hosts ASIC chips and turns electricity into hashrate. In other chip industries, manufacturers publish reference designs that show how to use a chip. Bitcoin ASIC makers publish none. Ember One publishes the PCB files, the bill of materials, and the interface a control board uses to drive the hashboard.
The first board, EmberOne/00, is a 100 W hashboard with twelve Bitmain BM1362 ASICs powered in series. It is only the hashboard. A separate USB-connected control board, such as Libre Board, runs mining firmware such as Mujina.
No heatsink or water block is part of the design yet. You provide the cooling for the ASICs and the power MOSFETs. The hashboard has no fan connector. See Cooling.
The picture above is the KiCad render shipped in the v6.1 design files. It is not a photograph of a built board.
v6.1 is the latest revision of EmberOne/00. This site describes those design files.
v6.1. The link stays on this branch until the revision is verified and released. See Design files.
