rev1.1
4f9402a

Revision 1.1 of the CellKeeper main board, as ordered from JLCPCB on 2026-10-28. The board has not been built or tested yet.

Files

  • CellKeeper_REV1.1_gerbers.zip: Gerbers and drill files
  • CellKeeper_REV1.1_bom.csv: BOM for JLCPCB assembly (DNP parts left out)
  • CellKeeper_REV1.1_positions.csv: pick-and-place (CPL) for JLCPCB assembly
  • CellKeeper_REV1.1_schematic.pdf: schematic
  • CellKeeper_REV1.1_board.pdf: 3D views of the top and bottom as assembled (pages 1-2), then board prints at 1:1 (pages 3-4: print those on A3 at 100 %): top, and bottom seen from below
  • CellKeeper_REV1.1_enclosure_print_files.zip: the 3D-printable case: print-oriented STEP and STL files (whole, two-colour and split versions), the bracket screw, the assembly STEP and the Bambu Studio project

The KiCad project at this tag also has the production files under CellKeeper/production.

Changes since rev1

  • USB VBUS sense on GPIO3, a board-revision strap, and an extra cap on the shunt's 3V3
  • 3V3 regulator for the INA228's isolated zone
  • RP2350 symbol: one symbol for the RP2350B or RP2354B (U14, U20). This build uses the RP2354B with its 2 MB in-package flash
  • W25Q16JV footprints (U23, U24) on each MCU's QSPI bus for an RP2350B build. They are DNP here, because the RP2354B's own flash uses the same pins and chip select
  • H0505S-1WR2 courtyard extended 0.6 mm
  • Back silkscreen realigned, a silkscreen clearance hole around JP37, and embedded fonts
  • 3D-printable enclosure in enclosure/

Further work continues on the rev1.2 branch.
