Context Before
50VDC enters the Strata Board via one of the 50V power connectors on both sides of the Strata board.
Evidence
50VDC is stepped down to 12VDC by the IBC module at the bottom of the Strata Board.
Context After
Then the 12VDC will be stepped down to 1VDC by the VRM before feeding into the Rubin GPU and Vera CPU. Strata directly receives 50VDC whereas the Bianca board of Grace Blackwell receives 12VDC from the PDB.
② Atomic Claim
位於 Strata Board 底部的 IBC module 將 50VDC 降壓至 12VDC。
