Notes

Checked README, both BOMs, the build-guide index, printable-file index and per-domain license at source commit 217d93f on 2026-10-23. Kept as draft because the source leaves power bank, cable, several input parts and some electrical ratings unspecified; radio modules are optional and excluded. The README mentions blower cooling but neither BOM lists a fan, so cooling hardware remains unconfirmed.

A weekly email of new build manifests and parts deals is coming soon.
