Where Libre Board Is Today ​

Revision 3 is the current design. Boards have been assembled, and they are under bench test. This page is the validation record. Design goals is the roadmap. Other pages describe the board as it is drawn.

Current as of 9 November 2026

Checked against the rev3 branch of 256foundation/libreboard, commit 0dbe8d1 (9 November 2026), which adds test/board-test. Follow the work is where a later result shows up.

What is in hand ​

  • The Revision 3 KiCad design, bill of materials, and JLCPCB order files are on the rev3 branch. main is still Revision 2. See Revisions.
  • Rev 3 boards have been assembled and are on the bench. The bench procedure is test/board-test on that branch.
  • The published automatic result in that directory is for one board, dated 9 November 2026: 41 pass, 1 fail, 1 warning. The fail is U17 (TCA9538) not fitted yet. The warning is no coin cell in BT1. The same note records Ethernet at 1000 Mb/s with no loss, the TUSB4041 hub enumerating, an NVMe read, and the 5 V rail up, with no kernel errors on that run.
  • That is one board's automatic checks. It is not a finished validation of Revision 3.

What comes next ​

Build and bring-up guides come after Rev 3 validation, on the assumption that validation does not find something a new revision has to fix.

Issue 27 is an open note about the USB 2.0 pairs from the hub (U11) to J1, J6, J10, and J17. It proposes a Rev 4 routing cleanup and says the current routing is expected to work and is still unproven. It does not decide that Rev 4 will be built.
