Excellent value for money
Compared to other boards with similar specs, this offers the best price-to-performance ratio. The inclusion of a battery charging circuit is a huge plus for portable applications.

Great hardware, documentation could be better
The build quality is solid and the SIM7670G module provides excellent global coverage. I deducted one star because the pinout diagram in the wiki was slightly confusing for the UART pins, but community forums helped clarify it quickly.

Reliable GPS and LTE
I've tested this in both urban and rural environments. The signal retention is strong, and the switch between Wi-Fi and 4G is seamless. Highly recommend for anyone building asset trackers.

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 with a standard SIM card, and the GNSS accuracy is impressive. Setup with ESP-IDF was straightforward.

Easy to flash and debug
The USB-C interface makes flashing firmware very convenient. I appreciated the clear labeling on the PCB. It supports MicroPython well, making rapid prototyping very easy.

Solid performance for industrial use
We deployed ten of these for a pilot study. They have been running continuously for three weeks without issues. The only minor issue is that the antennas are sold separately, which should be noted clearly.
Q: Does the GNSS work indoors?
A: Like all GPS/GNSS systems, signal acquisition indoors is limited and depends on window proximity or signal reflection. For best results, we recommend testing with a clear view of the sky or using an external active antenna placed outdoors.
Q: What software frameworks are supported for development?
A: This board is fully compatible with the Espressif ESP-IDF, the Arduino IDE (via the ESP32 core), and MicroPython. Example code for 4G and GNSS is available in our GitHub repository.
Q: Does this board come with the cellular and GPS antennas included?
A: No, the board features IPEX connectors for antennas, but the cellular, Wi-Fi, and GNSS antennas must be purchased separately to ensure optimal signal performance.
Q: Is the SIM card slot compatible with nano-SIM cards?
A: Yes, the SIM7670G module on this board uses a standard Nano-SIM card slot. Please ensure your carrier supports the LTE bands relevant to your region.
Q: Can I power this board directly with a 3.7V Li-Po battery?
A: Yes, the board includes a built-in battery management system. You can connect a single-cell Li-Po battery directly to the designated battery header, and it will handle charging via USB and power regulation.
