Trabajo realizado
  • Completé las conexiones de CAN (U7), FRAM I2C (U8) y LoRa (U9) con alimentación, señales, desacoplos, pull-ups, terminación DNP, TVS y conectores requeridos.
  • Añadí las notas de diseño y el estado ERC en Communication Block Notes.
  • Verifiqué las nets clave: 3V3, GND, CAN_TX, CAN_RX, CANH, CANL, I2C_SDA, I2C_SCL, SPI_CLK, SPI_MOSI, SPI_MISO, SPI_CS_LORA, LORA_M0, LORA_M1, LORA_AUX, LORA_RXD, LORA_TXD y ANT_LORA.
Revisión de criterios
  • ✅ Bloques CAN/FRAM/LoRa conectados con los componentes especificados.
  • ✅ Pasivos, TVS, conectores y notas de diseño añadidos.
  • ✅ ERC objetivo para U7/U8/U9 y nets LoRa revisado sin errores/advertencias nuevas; el proyecto completo aún tiene advertencias preexistentes fuera de estos bloques.
Siguientes pasos
Puedo continuar con el layout PCB: colocar estos nuevos pasivos/conectores cerca de sus ICs, ubicar J_CAN/J_ANT_LORA en borde de placa y preparar la ruta RF de 50Ω para ANT_LORA.

ESP32-S3 Wiring Notes
Completed connectivity
  • U3:3V3 is connected to the existing 3V3 power portal.
  • U3 ground pins GND_1 through GND_11 are connected to GND.
  • ESP32-S3 signal pins are connected with net labels for SPI, I2C, CAN/TWAI, UARTs, LoRa control, ADC inputs, 1-Wire, flow interlock, PWM outputs, panel buttons/LEDs, and checkpoints.
Required schematic notes
  • CAN_TX / GPIO19: USB_D+/CAN_TX – mutually exclusive
  • CAN_RX / GPIO20: USB_D-/CAN_RX – mutually exclusive
  • LORA_AUX / GPIO3: strapping pin – verify HIGH at boot
Passive availability check
Existing passives found in the schematic:
  • R1 = 2kΩ, already used for charger ISET.
  • R2 = 10kΩ, already used for charger TS/MR.
  • C1 = 100µF 35V, power input bulk capacitor.
  • C2 = 220µF 16V, 5V output bulk capacitor.
No unused/dedicated 10kΩ resistor or 100nF capacitor was found for the ESP32-S3 EN reset RC network or GPIO3 pull-up, so no new EN/GPIO3 passive connections were made because the instruction was to avoid adding components.
Validation notes
ERC currently reports U3:EN and U3:IO0 as floating. EN remains floating due to missing existing reset RC passives. IO0 was not in the requested connection list and no BOOT component/passive exists in the current schematic.
