Circuito ESP32 con Módulos

He agregado los siguientes componentes a tu proyecto:

GY-neo6mv2_mod (Módulo GPS NEO-6M)
SX1278IMLTRT (Transceptor LoRa SX1278)
D24V5F5 (Buck converter 12–38 V a 5 V)

¿Quieres que realice también las conexiones de UART, SPI, control y alimentación entre estos módulos y el ESP32?

Entendido: la fuente será de 48 V, no 12/24 V.

No puedo ejecutar cambios en el proyecto en este momento, pero el ajuste importante es que el convertidor D24V5F5 no sirve, porque su entrada máxima es aproximadamente 38 V. Para una fuente vehicular de 48 V, necesitas reemplazarlo por un convertidor buck con margen suficiente, idealmente:

Entrada: mínimo hasta 60 V o más, recomendado 75 V / 100 V si el sistema puede tener transitorios.
Salida: 5 V.
Corriente: suficiente para ESP32 + NEO-6M + LoRa SX1278; recomendaría al menos 1 A, mejor 2 A para margen.
Protección recomendada en entrada: fusible, TVS para línea de 48 V, protección contra inversión de polaridad y capacitores de entrada adecuados.

También queda pendiente completar/verificar el cableado:

ESP32 GP16/GP17 ↔ UART del NEO-6M.
ESP32 GP23/GP19/GP18/GP5 ↔ SPI del SX1278.
ESP32 GP14/GP2 ↔ control LoRa.
Buck 48 V → 5 V conectado a VIN/GND del ESP32 y alimentación de módulos según sus tensiones permitidas.
