Excellent value for money
I bought this for a smart agriculture project. The ability to switch between WiFi and cellular backup ensures my sensors stay connected even when the local network drops. Highly recommended for industrial control applications.

OTA feature is a game changer
The remote upgrade capability saved us hours of manual flashing. The board connects reliably to our cloud server, and the power consumption is reasonable for battery-operated scenarios. A must-have for serious developers.

Great hardware, documentation could be better
The hardware quality is solid and the signal range on the LoRa module is impressive. However, I had to dig into community forums to find specific examples for the 4G module initialization. Once set up, it runs very stably.

Ideal for learning embedded systems
As a student, this board provides everything I need to learn about modern communication protocols. The pinout is clearly labeled, and the build quality feels professional. It handles the STM32CubeIDE environment without issues.

Robust for field testing
We used these boards for a pilot deployment in a factory setting. They handled the electrical noise well and the long-range LoRa communication was stable across the facility. Deducting one star only because the SIM card slot is a bit tight.

Perfect for IoT Prototyping
This board exceeded my expectations. The integration of LoRa, WiFi, and 4G on a single STM32 platform makes prototyping complex IoT gateways incredibly fast. The OTA upgrade feature worked flawlessly during my tests.
Q: Does this board support Arduino IDE or only STM32CubeIDE?
A: The board is primarily designed for STM32CubeIDE and HAL libraries, but it is also compatible with the Arduino IDE if you install the appropriate STM32 core packages. Most example codes are provided for STM32CubeIDE.
Q: Is the 4G module unlocked for any carrier SIM card?
A: Yes, the onboard 4G LTE module is unlocked and supports standard Nano-SIM cards from most global carriers. Please ensure the frequency bands match your local provider's network.
Q: Where can I download the schematic and datasheet?
A: You can find the full schematic, pinout diagrams, and datasheets in the 'Documents' section of the product page or on our official GitHub repository linked in the user manual.
Q: What is the maximum transmission distance for the LoRa module?
A: In open line-of-sight conditions, the LoRa module can achieve distances of up to 5-8 km depending on the antenna used and environmental factors. In urban environments with obstacles, expect ranges between 1-3 km.
Q: Can I power this board directly with a 12V battery?
A: No, the board operates on 5V input via the USB-C port or the 5V header pin. Connecting 12V directly may damage the components. We recommend using a separate buck converter to step down 12V to 5V before connecting to the board.
