I reviewed your replacement plan and proceeded as far as possible: I confirmed and recorded that we will stay within the ESP32‑C3 family and recommended using a module for simpler RF/antenna integration (ESP32‑C3‑MINI‑1 style) — those two decisions are DONE; I also documented the remaining required decision (1.1.3) about how to handle the RF/antenna/footprint (options A/B/C) and set the default fallback to an ESP32‑C3 module exposing an RF pad if you don’t reply, prepared the library search queries and verification checklist (voltage, RF interface, XTAL, pinout, peak TX current) to shortlist candidates, and outlined the grouped schematic replacement, power/regulator checks, passive updates, and validation steps I will run once you choose A/B/C; the automated run timed out before the library search and replacement steps could complete, so I’m waiting for your short reply (“A”, “B”, or “C”) to continue and finish the part selection, schematic updates, ERC/DRC checks, and final deliverables.
