Specifications
Figures for the EmberOne/00 design files on the v6.1 branch. The nominal hashrate remains unverified on this revision.
Current as of November 4, 2026
Describes the latest revision, on the v6.1 branch. The default branch, master, is older. See Design files.
EmberOne/00
| Item | Value |
|---|---|
| Power class | 100 W |
| Input voltage | 12–16 V DC. The regulator's maximum power input is 16 V. See Input voltage. |
| ASICs | 12 × Bitmain BM1362, powered in series. The v6.1 footprints are BM1362AC. |
| ASIC variants | BM1362AA, AB, AC, and AD. The v6.1 README says AI and BD are untested, and that AJ and AK will not work. |
| Hashrate | 3.6 TH/s theoretical nominal. Not yet verified on rev6.1. See Hashrate. |
| Board size | 125 × 125 mm, measured on the v6.1 board outline |
| Core regulator | TPS546D24A |
| IO voltage | 6 V VDDIO. The v6.1 schematic labels a TPS61041 "VDDIO 6V Boost Regulator". |
| Board controller | RP2040, running emberone-usbserial-fw |
| Host interface | USB, to a separate control board |
| Temperature sensors | TMP1075 and TMP451 on the v6.1 schematic. The Mujina driver reads both. |
| Cooling | No heatsink or water block is included. You provide cooling for the ASICs and the power MOSFETs. The hashboard has no fan connector. See Cooling. |
| Design tool | KiCad |
| License | Hardware: CERN-OHL-S-2.0. USB-serial firmware: GPLv3. |
Input voltage
The input range is 12–16 V DC. The TPS546D24A core regulator sets the 16 V ceiling. The TI datasheet, section 6.3, specifies 16 V maximum for the power-stage input, PVIN. The separate controller supply, AVIN, supports 18 V. That does not raise the power-stage input limit.
The v6.1 README and silkscreen's 17 V upper limit need correction. The correction is tracked in issue #50.
Hashrate
The theoretical nominal hashrate is 3.6 TH/s.
Not yet verified on rev6.1
This is a theoretical figure, not a measured result for rev6.1. Hardware verification on this revision is still required.
Cooling
Ember One does not yet include a heatsink or a water block. For development and testing, you design, adapt, or provide the cooling yourself. It has to serve the ASICs and the power MOSFETs.
The hashboard has no fan connector. A separate control board, such as Libre Board, may have fan connectors of its own. Those connectors are on the control board. They are not a heatsink or a water block for this hashboard, and they are not a validated thermal design.
Validation
What a revision's test status allows anyone to claim is unsettled. The wording lives on Where Ember One Is Today. Boards have run real hashrate. See that page for the record, and for the open question beside it.
