Ideal for university projects
Used this for my final year project involving remote sensor data logging. The LTE connectivity worked out of the box with a standard SIM card. Highly recommended for students.

Robust for industrial control
We tested this for a small scale RTU application. The temperature range holds up well and the GPIO pins are robust enough for direct sensor interfacing.

Good value for money
For the price, you get a lot of connectivity options. The only downside is that the antenna connectors feel a bit fragile, so handle with care during assembly.

Great hardware, steep learning curve
Hardware quality is excellent and power consumption is low as advertised. However, getting the initial Python environment set up took some time compared to other boards.
Q: Is there an onboard debugger included?
A: The board features a built-in USB-to-UART converter for debugging and flashing firmware, so no external debugger is required for basic development.
Q: Can I power this board directly via USB?
A: Yes, you can power the board via the Micro-USB port, but ensure your USB source can provide at least 500mA for stable LTE operation.
Q: Which cellular bands does this module support?
A: It supports major global LTE FDD bands including B1, B3, B5, B8, B20, and B28. Please check the specific datasheet for your region's compatibility.
Q: Does this board support MQTT protocol natively?
A: Yes, the board supports MQTT through its Python libraries, allowing easy integration with most cloud IoT platforms.
Q: What is the maximum data speed for the 4G Cat1 connection?
A: The 4G Cat1 module supports up to 10 Mbps downlink and 5 Mbps uplink, which is ideal for telemetry and low-bandwidth applications.
