Other Information

Setup & Integration

Connect the 4G antenna and insert a Nano SIM with valid 4G service. A micro SD card up to 16GB may be used for data logging or storage. Use a regulated 9-30V DC, 2A power supply with correct polarity. RS485 or RS232 is selected using the jumper selector. USB Type-B is used for programming and serial monitoring.

Notes and Precautions
  • Before reprogramming the ESP32-S3, understand the 4G module AT commands. Incorrect commands can alter or corrupt module configuration.
  • The module is not intended for direct mobile calling because speaker and microphone are not present on the board.
  • For Arduino IDE programming, ensure USB CDC on Boot is enabled.
  • ESP32-S3 strapping pins are GPIO 0, 3, 45 and 46. GPIO 35, 36 and 37 are internally used by the 8MB PSRAM and should be used with caution.
  • Only one of RS485, RS232 or CAN communication can be used at a time depending on jumper setting.
  • RFM95W can be used as a LoRa transmitter / receiver, but the hardware does not support use as a LoRaWAN gateway.
