ESP32 4G LTE Gateway (Gen.1)

Connect Everything

• Wi-Fi and Bluetooth (over u.FL connector)
  The ESP32-WROOM-32U (8 MB) module on board takes care of all your Wi-Fi networking needs. The u.FL connector ensures that you have the flexibility of connecting any antenna of your choice.
• 4G LTE with GSM fallback (over SMA connector)
  Stay connected in remote locations with 4G connectivity. GSM still works if 4G LTE is unavailable – making this the best solution to stay connected. An SMA antenna connector lets you place your antenna for maximum coverage.

  •LTE-FDD B1/B2/B3/B4/B5/B7/B8/B28
  •UMTS/HSPA+ B1/B2/B5/B8
  •GSM/GPRS/EDGE 850/900/1800/1900MHz
  SIM7600E:
  •LTE-TDD B38/B40/B41
  •LTE-FDD B1/B3/B5/B7/B8/B20
  •UMTS/HSPA+ B1/B5/B8
  •GSM/GPRS/EDGE B3/B8
• GNSS (over u.FL)
  Track location-dependent data with the GNSS receiver on board. Requires an active antenna to be connected for best results.
• Ethernet
  The ethernet connector on board enables communication with advanced PLC devices and implementation of modbus over TCP/IP.
• RS-485
  Our gateway has you covered if you need to connect to devices over RS-485. The Gateway is equipped with a 10 mbps RS-485 transceiver.
• 5V and 3.3V Sensors with I2C
  You can easily interface low power sensors over I2C (like environment sensors). All you have to do is plug them into the JST-XH sensor header. As long as the sensors draw a total current of less than 250mA, the Gateway can power them all.
