Impressive range and speed
The LTE Cat-1 speeds are sufficient for sending telemetry data and occasional images. The antenna connections are robust, and I appreciate the dedicated power management circuit for the cellular module.

All-in-one solution
Having Wi-Fi, Bluetooth, 4G, GPS, and a camera on a single small board saves so much wiring hassle. I used this for a wildlife tracker and it performed beautifully for weeks on a battery pack.

Great hardware, documentation could be better
The build quality is excellent and the SIM7670G module handles signal well even in fringe areas. I deducted one star because some of the Python library examples for the camera were a bit outdated, but I got it working eventually.

Solid choice for industrial apps
We deployed five of these for asset tracking. They connect reliably to the network and the GPS lock time is fast. Just ensure you have active SIM cards compatible with the bands in your region.

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 positioning is surprisingly accurate. Setting up the camera stream was straightforward with the provided examples.
Q: Does this support MQTT protocols for cloud connectivity?
A: Absolutely. The ESP32-S3 chip fully supports MQTT over both Wi-Fi and the 4G cellular connection, making it ideal for AWS IoT, Azure, or private MQTT brokers.
Q: What is the power consumption when the 4G module is transmitting?
A: During peak transmission, the 4G module can draw up to 500mA. We recommend using a stable 5V/2A power supply or a high-drain Li-Po battery for reliable operation.
Q: Can I use a standard Nano SIM card with this board?
A: The board features a Nano SIM card slot. Please ensure your SIM card is activated for data and compatible with the 4G bands supported by the SIM7670G in your country.
Q: Does this board come with an antenna for the 4G module?
A: Yes, the package includes a 4G LTE antenna with an IPEX connector specifically designed for the SIM7670G module.
Q: Is the camera resolution adjustable via software?
A: Yes, the OV2640 camera supports multiple resolutions ranging from QQVGA up to UXGA (1600x1200), which can be configured easily through the ESP-IDF or Arduino IDE libraries.
