BREAD / GUIDES
Supported scope and limits
Static modeled connectivity is the contract. It is not simulation or hardware qualification.
Finite supported families
| Family | Current boundary |
|---|---|
| Single LED | One resistor and LED on D12 or D13, with GND1 return. |
| Multi LED | 3–6 branches render. Two branches are unsupported; 7–12 fail placement capacity. |
| Mixed | Exactly the DHT22, button, trimmer and LED family; three distinct D2–D13 roles and A0 wiper. |
| Diode LED | Exactly one diode/resistor/LED series chain and at most one 100nF capacitor. |
One fixed board
The board has 30 rows, A–E and F–J isolated strips, a center gap and no power rails. Each hole has at most one lead or jumper. Physical reconstruction uses inserted leads, sockets, strips and jumpers independently of the expected logical nets.
Placement and routing are deterministic heuristics. Rejection does not prove that every real-world layout is impossible. Six LEDs have 17 crossing points; the shipped mixed example has 8. Crossings are not junctions.
What remains unverified
No voltage/current/thermal analysis, physical assembly, wire insulation or bend-radius model, firmware execution, simulation, or beginner usability study is included. Sensor under-body wire clearance and full label/stroke separation remain limitations.
