Context Before

50VDC enters the Strata Board via one of the 50V power connectors on both sides of the Strata board. 50VDC is stepped down to 12VDC by the IBC module at the bottom of the Strata Board.

Evidence

Then the 12VDC will be stepped down to 1VDC by the VRM before feeding into the Rubin GPU and Vera CPU.

Context After

Strata directly receives 50VDC whereas the Bianca board of Grace Blackwell receives 12VDC from the PDB.

② Atomic Claim

之後 VRM 再把 12VDC 降至 1VDC，供給 Rubin GPU 與 Vera CPU。

⑤ Human Review

請在 Properties 逐項確認：

• 原文 → Atomic Claim 是否忠實
• Atomic Claim → Semantic Frame 是否忠實
• Canonical Entity mapping 是否正確
• Epistemic mode 是否保留原文語氣
