Assembly readyATtiny85 Charlieplex LED Grid
02-charlieplex-led
Manufacturing readiness
Checked .
Scope: PCB fabrication and assembly files.
Fabrication tier: jlcpcb.
Current evidence passes the assembly release checks; this does not establish tested hardware performance.
- zone fill: passed — Saved copper area agrees with an independent refill on 0 layer(s).
- Connectivity and design checks: passed — 0 electrical/manufacturing errors; DRC and ERC sub-checks passed; warning counts: none. Manifest verification is deferred to the artifacts gate.
- Native design rules (DRC): passed — 0 error-level findings on saved copper.
- native refilled drc: passed — 0 error-level findings on saved copper.
- lvs: passed — LVS PASSED over 48 bound pad(s).
- warning review: passed — Per-rule warning table reviewed: none.
- Manufacturing artifacts: passed — Fresh assembly bundle of 33 file(s); SHA256 integrity and source ZIP provenance verified.
- Bill of materials: passed — 8 BOM line(s) carry procurement identifiers; part check WARN: 0 of 19 assigned item(s) verified (no source); 19 unverifiable (not in parts cache or offline catalog) [unverified: U1 -> C965497, J1 -> C7501260, J2 -> C65114, C1 -> C49678, C2 -> C1779, R5 -> C17414, R1 -> C17630, R2 -> C17630 (and 11 more)]; CPL includes 3 through-hole component(s) for fab assembly.
- firmware: passed — Sources and programmed image byte-identical to the AVR GCC 7.3.0 compiled audit (214 flash bytes, 22 RAM bytes); Intel HEX record checksums verified and flash size re-measured (214 bytes). avr-gcc not installed here, so no rebuild. Physical hardware bring-up remains untested.
- smt drill clearance: passed — Issue #5012 actual-land overlap rule re-run (jlcpcb, 2 layers): 0 overlaps; all 11 reviewed via relocations present on their nets. Ordinary JLCPCB process.
- native erc: passed — Fresh native KiCad ERC: 0 errors, 0 warnings.
Passed: this check passed for the recorded files. Failed: this check found a problem. Not run: no result was established. Unlisted checks have no reported result.
