Firmware review: v2.3 as EinarBoard 1.0 production candidate (2026-07-24)
Verified findings: millis()-rollover recovery-gate collapse (uint32-modelled), fan-tach false-fault on 2-wire fans, PROD silicon undriven (CHRG_EN/STAT/FAULT, BYP_CTRL/K1, NTC PB1, gauge). v3.0 scope in doc section 4. Bumps firmware submodule to ea1d84c (v2.2+v2.3 source + tools/hostsim harness).

2026-07-02: PROD schematic complete (ERC 0) + carrier-board PCB + doc sweep to the Jul-2 ledger
Electrical/PCB:
- LTC4040 Block B sized to the 12 Ah 1S4P pack (RPROG 825R -> 2.42 A ~ C/5,
RS 8 mR -> 3.1 A input limit, PFI 4.60 V, backup 4.79 V, charge 4.00 V Li-ion
via VSYS-referenced straps) + Block E cutoff (P11) + Block F PA4->VEH5V re-tap
+ Block H fail-safe Modo-B bypass (K1 normally-closed relay) + Block I NTC->PB1.
- CARRIER-BOARD conversion: simpleRTK2B Pro on UNO-pattern female headers (MOD1;
D0/D1=UART1, D2=RX2, D8=TX2, IOREF=3V3, 5V=SW_5V) + 4G NTRIP Master on on-board
XBee socket (J7/J8; VCC=3V3_MODEM via new Block K MP1584 buck off SW_5V - the
HP XBee socket is 3.3 V not 5 V). Board 120x100, placement + GND pour + DRC
baselines. Custom symbols: LTC4040EUFD, AO4406A, SimpleRTK2B_Pro_Socket.
- Fixed duplicated U2, stale no-connects, A4->A3 sheet; ERC 0 errors.
Docs:
- Canonical electrical-design-state + production delta (Block B values table,
5b/5c/5d/5e) + design/rationale/connections/BOM swept to the Jul-2 assumptions
ledger (Conexiones-por-Bloque xlsx).
- Guia de Conexion Protoboard: LaTeX source now maintained in-repo -> v2.1 PDF.
- CircuiTikZ sheet + wiring Beamer: block 11 (NTC->PB1) + guinda ignition legend.
- Client decks: Avance v1.1 (overclaims fixed) + RCA v1.1 (2-jul addendum).
Repo hygiene:
- .gitignore: live rtk-config (SIM/APN/NTRIP creds) now ignored and REMOVED from
tracking (NOTE: rotate those credentials - they exist in prior commits);
KiCad .bak/snapshots/.history, LaTeX intermediates, Office locks ignored+purged.
- Removed rogue .history gitlinks that broke git status.
