Perfect for IoT Projects
This board is exactly what I needed for my smart home automation project. The 4G connectivity is stable, and the API documentation made secondary development straightforward. Highly recommended for developers.

Great hardware, learning curve on software
The relay module works flawlessly and handles the load well. Setting up the initial SMS commands took a little time to figure out, but once configured, it responds instantly. Good value for the price.

Works well but needs better manual
The device functions as described, but the included manual is a bit sparse on details for advanced timing configurations. Had to contact support to get the full command list. Hardware quality is solid though.

Robust for industrial use
Installed five of these in our warehouse for lighting control. They have been running for three months without a single dropout. The ability to trigger via phone call is a great backup feature.

Solid module for the price
Good build quality and the terminals are easy to wire. The app interface is basic but functional. If you know how to code, you can really unlock its potential with the open API.

Reliable for remote irrigation
We use these to control water pumps in fields with no Wi-Fi. The 4G signal picks up even in rural areas. The timing feature saves us a lot of manual work. Very satisfied.
Q: Does this module come with a SIM card included?
A: No, the SIM card is not included. You will need to purchase a standard size SIM card with an active data plan from your local carrier separately.
Q: What programming languages are supported for secondary development?
A: The module supports standard HTTP/MQTT protocols, allowing you to develop using Python, Node.js, C++, or any language that can send web requests. Full API documentation is available for download.
Q: Can I control multiple relays independently using one module?
A: This specific model features a single high-capacity relay. If you need independent control of multiple circuits, please check our 4-channel or 8-channel variants in the store.
Q: Can this be powered directly by a 12V car battery?
A: Yes, the input voltage range is DC 5V to 24V, so it is fully compatible with a 12V car battery system. It includes protection against voltage spikes commonly found in automotive environments.
Q: Is there a monthly fee for using the mobile control features?
A: There is no monthly fee charged by us. You only need to pay for the standard data or SMS costs associated with the SIM card plan you choose from your telecommunications provider.
