Perfect for IoT Prototyping
This board is exactly what I needed for my remote sensor project. The 4G connectivity works flawlessly out of the box, and the GNSS positioning is surprisingly accurate. Setup with MicroPython was straightforward.

Great hardware, documentation could be better
The build quality is excellent and the SIM7670G module covers all the bands I need for international deployment. I deducted one star because some of the pinout diagrams in the wiki were slightly outdated, but support helped me quickly.

Reliable for industrial telemetry
We deployed ten of these units for vehicle tracking. They have been running continuously for three months without a single dropout. The signal strength indicators are very helpful for antenna placement.

A staple in our lab now
We bought a batch for our university lab. Students love that they can test cellular and GPS concepts without needing complex external shields. Robust construction handles student usage well.

Good learning board
As someone new to embedded systems, this board was a bit challenging at first, but the community examples helped a lot. Once I got the APN settings right, the data transmission was instant.

Excellent value for money
Compared to buying separate modules for WiFi, BLE, 4G, and GPS, this all-in-one solution saves so much space and wiring headaches. The power management is also very efficient for battery-operated projects.
Q: What voltage should I use for the Li-Po battery connection?
A: The board supports standard single-cell Li-Po batteries (3.7V nominal). The onboard charging circuit manages the charging process safely when powered via USB.
Q: How do I access the GNSS data?
A: GNSS data is accessible via the dedicated UART interface. We provide sample code in both C++ and Python that parses NMEA sentences to extract latitude, longitude, and altitude.
Q: Is this compatible with Arduino IDE?
A: Yes, the ESP32-S3 core is fully supported by the Arduino IDE. You will need to install the ESP32 board package and select the appropriate board definition to start programming.
Q: Does this board come with antennas included?
A: No, the board features IPEX connectors but does not include the actual antennas. You will need to purchase compatible 4G, Wi-Fi, and GNSS antennas separately based on your specific frequency requirements.
Q: Can I use this for global roaming?
A: Yes, the SIM7670G module supports multiple LTE bands covering North America, Europe, Asia, and Australia. However, you must ensure your SIM card provider has roaming agreements in your target regions.
