Private 4G LTE IoT Gateway
Build a Self-Powered Private 4G LTE IoT Gateway with Arduino Mega
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Deploy your own private 4G LTE IoT gateway that collects temperature, humidity, and pressure data from off‑grid locations and publishes MQTT messages to any cloud platform. This kit equips you with a complete Arduino Mega and SIM7600 system, solar‑powered and enclosed for real‑world field use. Whether monitoring farmland, remote pipelines, or forest sensor networks, you gain full control over your cellular data pipeline.
What You'll Build
A fully functional IoT gateway that uses the SIM7600 module on Arduino Mega to connect to 4G LTE networks, gather sensor data from the included DHT22 and BMP280, timestamp it with the DS3231 RTC, log to microSD, and transmit MQTT payloads over the internet—all powered by a rechargeable solar system. The waterproof enclosure makes it ready for outdoor installation.
What You'll Learn
- Configure AT commands for the SIM7600 4G LTE module and establish a PPP data connection.
- Write Arduino code to parse and publish MQTT topics over an LTE network using the PubSubClient library.
- Design a solar charging circuit with TP4056, 18650 cells, and an LM2596 buck converter for 24/7 field operation.
- Integrate multiple I2C sensors and an RTC, store data on microSD as CSV, and handle real‑time clock synchronization.

Who This Kit Is For
Engineers, researchers, and advanced makers needing a reliable cellular backbone for remote sensor networks. Ideal for B.Tech final‑year projects in ECE/EEE, Smart India Hackathon teams focused on agritech or environmental monitoring, and professionals prototyping industrial IoT solutions. The advanced nature suits those with prior Arduino experience and an understanding of basic networking, allowing you to graduate from Wi‑Fi‑dependent projects to standalone 4G deployments.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
The AI companion walks you through each wiring and code step; if you still need help, direct WhatsApp support is included with the kit.
Can this gateway send data to my own MQTT broker?
Yes, you can configure any broker URL in the Arduino code. The companion AI covers TLS setup for secure connections.
Does the solar panel keep the system running at night?
The two 18650 cells provide enough capacity for typical sensor logging and nightly MQTT transmissions; the AI companion includes a power budget calculator tailored for your use case.
Is this kit suitable for agricultural remote monitoring?
Absolutely. The waterproof enclosure and solar power make it ideal for farm weather stations. You can easily add soil moisture or other sensors (not included) using the many spare Mega I/O pins.
SIM7600 4G LTE module on Arduino Mega creates a cellular data gateway publishing MQTT over LTE for remote locations.
