Best board for learning cellular IoT
As a student, this board gave me everything I needed to learn about LTE-M and NB-IoT without buying separate modules. The community support is helpful, and examples are available on GitHub.

Great hardware, documentation could be better
The build quality is excellent and the A7670E module provides stable LTE coverage. However, finding specific pinout diagrams for the camera interface took some digging in the wiki. Once set up, it performs wonderfully.

Impressive performance
I am using this for a mobile robot project. The dual-core processor handles image processing from the camera while maintaining a stable 4G connection for telemetry. No lag or disconnections so far.

All-in-one solution
Having WiFi, Bluetooth, 4G, and GPS on a single small board saves so much space in my enclosure. The USB-C programming interface is a nice touch. Highly recommended for industrial data loggers.

Perfect for IoT Prototyping
This board is exactly what I needed for my remote monitoring project. The 4G connectivity works flawlessly out of the box, and the GNSS module locks onto satellites quickly. Integration with MicroPython was smooth.

Solid choice for edge computing
Works great with AWS IoT Core. The only minor issue is that the SIM card slot feels a bit tight, but once inserted, the connection is rock solid. Good value for the features provided.
Q: Is the camera module included in the package?
A: No, the development board does not include a camera module. It has a connector compatible with common OV2640 or OV5640 cameras which must be purchased separately.
Q: Does the GNSS work indoors?
A: GNSS signals are weak indoors. For best results, an external active antenna should be connected to the U.FL connector if used inside buildings.
Q: Can I power this board directly from a LiPo battery?
A: Yes, you can connect a LiPo battery to the BAT header, but please ensure the voltage is within the specified range (3.7V-4.2V) and use a protected battery.
Q: What IDEs are supported for programming this board?
A: You can program this board using Arduino IDE, ESP-IDF, MicroPython, CircuitPython, and PlatformIO.
Q: Does this board support Nano-SIM cards?
A: Yes, the board features a standard Nano-SIM card slot compatible with most global carriers supporting LTE Cat-1.
