Doorbell is an open-source printed circuit board by gunnarbeutner, from the gunnarbeutner/doorbell repository on GitHub, published under the MIT licence. It is a 4-layer board of 64 × 59 mm with 119 parts on 91 nets, routed with 664 tracks and 147 vias.
It is built around the ESP32-S3-WROOM-1U-N16R8, ES8311 and LP5907MFX-3.3/NOPB(MS), with the CC0603KRX7R9BB104, LMBR01S30ST5G and H24VND3BA among its other parts. Its parts include 41 resistors, 23 capacitors, 17 diodes, 10 switches and 4 ICs. It belongs with the home automation and IoT boards and the ESP32 boards of this library.

KiCad. build.sh never authors copper; it runs the checks KiCad's own DRC/ERC can't
express and exports the fab outputs:
./build.sh # verify + all order-ready exports (full release)
./build.sh verify # ERC + placement + PCB/DRC + simulation; no exports
./build.sh schematic # schematic ERC + PDF export
./build.sh pcb # placement + planes/thieving/connectivity + DRC
./build.sh simulation # circuit-simulator tests

./build.sh step # populated STEP model
./build.sh board-step # bare-board STEP model| Script | Interpreter | Role |
|---|---|---|
tools/check_pcb.py | KiCad bundled python (pcbnew) | verify placement (edge flush/overhang, parts inside outline) |
tools/route.py | KiCad bundled python (pcbnew) | refill zones + verify connectivity + copper-thieving sliver limit |

tools/doorbell_design.py holds the placement constants check_pcb.py verifies — connector edge
fit/overhang and the mounting-hole MLCC keep-out; the KiCad files are authoritative for the rest.
The board is hand-routed in KiCad;
route.py fails the build on any unrouted connection or any copper-thieving float island
over the sliver limit (≥ 2 mm² or ≥ 10 mm) — fix those in KiCad, never with a tool.
4-layer, ~64 × 59 mm;
tools/check_pcb.pygates placement (the edge connectors J1/J2/J3 and U1 sit flush on their board edges).
This README is only the build/verify/fab process. Everything else stays in its authoritative source so it can't drift out of sync — so there is no part list, net list, or pin table here:

HILprobe: multi-function UUT probe for hardware-in-the-loop testing - RS-485, CAN FD, logic analyzer, 4-ch scope, two programmable UUT supplies. KiCad 10, 6 layers, RP2350B + ESP32-S3.
It measures 64 × 59 mm and has 4 copper layers, 1.6 mm thick.
119 parts, built around the ESP32-S3-WROOM-1U-N16R8, ES8311, LP5907MFX-3.3/NOPB(MS) and CC0603KRX7R9BB104. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the gunnarbeutner/doorbell repository on GitHub, at the commit this page was made from: the board is kicad/doorbell.kicad_pcb and its schematic kicad/doorbell.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
