Contradictions, resolved against the design files: - GitHub repo description corrected to KiCad 10 and 6S (schematic/PCB carry generator_version 10.0; DOC_INPUT is "+BATT 6S", no 3S floor is documented). - DOC_NAME text variable now "OpenESC-20x20", matching the repo rename, so the old slug stops leaking into title blocks and fabrication exports. - 20x20-ESC-QC/README.md no longer claims project-local libraries only: 44 of the 45 fixture footprints come from KiCad's stock TestPoint library. Also records that the fixture schematic is a stub, so the one ESC-QC symbol is unused. - esc_thermal.py header and 20x20 profile name state that SP40N03GNJ is a superseded power stage and its numbers do not describe the shipping board (24x DOY180N03T). Parameters left untouched, re-parameterization needs the DOY180N03T datasheet. - *.kicad_dru removed from .gitignore: hardware/4in1-mini.kicad_dru is a hand-authored DRC rule, a design input, not generated output. - The "3D exports" ignore rule was malformed (**/.step matched nothing). Now hardware/*.step and 20x20-ESC-QC/*.step, which leaves the *.3dshapes/ library assets tracked. Duplication, each fact kept in one place: - README specification table dropped, the full table lives in DESIGN.md. - Production-export and flash-script statements kept in README Manufacturing; the layout rows and DESIGN.md now link there. - licensing/README.md removed, its one unique sentence moved into the README license section. THIRD_PARTY.md and TRADEMARKS.md keep the real content. Removed: - hardware/datasheets/COMPONENT_REVIEW.md, a v0.3 audit describing a power stage, current sense and regulator that are not in the design files. - hardware/scripts/v_beta_hygiene_fix.py, an applied migration whose target file and all three source strings no longer exist, and which byte-edits .kicad_sch against CONTRIBUTING. - hardware/4in1-mini.step (18.3 MB) and 20x20-ESC-QC/QC-20x20-PCB.step, regenerable board exports now correctly gitignored. - 20x20-ESC-QC/ESC-QC.pretty/.gitkeep, the directory holds a real footprint.

# 20x20-ESC-QC: press-contact QC fixture
|
|
|
|
Bench test/QC jig for the **OpenESC-20x20** (`../hardware/4in1-mini`). The
|
|
assembled ESC is pressed face-down onto this board so spring/pogo contacts land
|
|
on the ESC's exposed pads (power in, three phases per channel, signal lines) to
|
|
run functional and current-transfer tests without soldering leads.
|
|
|
|
Concept: this board is a **negative** of the ESC contact face. The ESC nests
|
|
into a milled/offset pocket for alignment, and contact features sit under each
|
|
of its exposed pads.
|
|
|
|
## Layout / conventions (mirrors the parent repo)
|
|
|
|
- KiCad 10 project: `20x20-ESC-QC.kicad_{pro,sch,pcb}`. The schematic is an empty
|
|
stub: the fixture is laid out directly on the board, with no netlist.
|
|
- Project-local libraries, declared in `sym-lib-table` and `fp-lib-table`:
|
|
- Symbols: `ESC-QC.kicad_sym` (one symbol, `4in1ESC-negative`, currently unused
|
|
because the schematic is a stub)
|
|
- Footprints: `ESC-QC.pretty/` (one footprint, `4in1ESC-negative`: 34 pads plus
|
|
the Edge.Cuts geometry of the ESC contact face)
|
|
- 3D models: `ESC-QC.3dshapes/` (empty)
|
|
- The 44 contact pads come from KiCad's stock global `TestPoint` library
|
|
(`TestPoint_Pad_2.0x2.0mm`, `3.0x3.0mm`, `4.0x4.0mm`), not from a project-local
|
|
library. Nothing else resolves globally.
|
|
- License: hardware CERN-OHL-S-2.0 (same as parent).
|
|
|
|
## Reference geometry
|
|
|
|
The contact locations must match the ESC's exposed pads exactly. Pad
|
|
coordinates and nets are extracted read-only from the source board,
|
|
`../hardware/4in1-mini.kicad_pcb` (kicad-cli or the pcbnew API); nothing in the
|
|
ESC design is modified.
|
|
|
|
## Contacts to hit (from the ESC design)
|
|
|
|
- **+BATT / GND**: high-current, the press-contact points that matter most.
|
|
- **Motor phases**: 3 per channel x 4 channels (A/B/C) motor output pads.
|
|
- **Signal**: 4 DShot lines (/M1-/M4) plus +BATT, GND, and /CURR on J1
|
|
(SM08B-SRSS-TB), or its pad footprint if contacting the pads directly.
|
|
- Optional: SWD/boot test pads for the AT32F421 per channel.
