Magnum Technical Concept

From idea to installation!
Our smart 3-source automatic changeover system is now fully live at Embedded TechLab.
What started as a concept is now a fully working digital smart automatic three-source changeover system, built to intelligently switch between generator, solar, and grid power (NEPA) depending on availability. The goal was to ensure an uninterrupted power supply while giving better control, visibility, and protection over energy usage.
This build went through several months of design, testing, and refinement; from PCB development and firmware programming to enclosure design, wiring, and final installation. With features like dual operation mode, mobile connectivity, real-time monitoring, and voltage protection, the system is designed to be practical and reliable for real-world use.
This final version reflects the effort put into multiple iterations, and it’s satisfying to see it now actively powering and monitoring operations at Embedded TechLab.
Special thanks to NextPCB for supporting the prototyping and production process, helping us achieve a clean and reliable hardware finish. More refinements and real-world deployments are in progress, and full documentation will be shared soon to

M25 Gateway – Custom LoRa Gateway!
The M25 Gateway is a purpose-built LoRa communication board designed at MEmbedded TechLab to manage and monitor multiple remote devices in real-time.
Developed around the ESP32-WROOM-32D, the system integrates:
-Long-range LoRa connectivity for multiple remote devices
-SIM868 module for GSM/GPRS and GPS capabilities
-Battery management with LM2596 and TP4056 modules
-16x2 I2C LCD for signal quality and device activity display
-Onboard alert and interaction components for field diagnostics
This gateway enables the reliable reception and aggregation of data from distributed sensors and transmitters, with support for server integration and offline operation.
Attached are images of the PCB design and working prototype.
