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.
