Case studies of pcbs with microcontroller

Microcontrollers are widely used due to their benefits. They can be programmed for different applications. The program is written based on the specific requirements for each project. When necessary the program can be changed without changing the hardware.

Case Study: Redesigning and Enhancing Battery Monitoring System

Project Overview:

Upon reviewing the requirements, it became evident that the original microcontroller was no longer in production, that was a challenge for the production process. To address this issue, we suggested replacing the outdated microcontroller with a newer and available one. This replacement would require redesigning the schematic and writing new firmware to replicate the functionality of the original PCB.

Our Solution:

Redesign and Firmware Development To ensure a seamless transition to the new microcontroller, our team analyzed the functions and schematic of the old PCB. We developed a new schematic that integrated the necessary components and connections for the upgraded microcontroller.

Simultaneously, custom firmware that would replicate the behavior of the original PCB was written. We thoroughly tested the firmware, ensuring it accurately measured battery voltage and activated the reserve power supply as per the clients requirements. This stage involved multiple iterations to refine and optimize the firmware performance.

Additional Features and Prototype Testing:

The new microcontroller provided an opportunity to enhance the battery monitoring system with additional features. After consulting with the client, we identified and incorporated functionalities that could improve the overall performance and usability of the device. These additional features included battery health diagnostics, real-time data logging, and remote monitoring capabilities.

Once the initial prototype was assembled, we collaborated closely with the client for field testing. The client provided valuable feedback, allowing us to make necessary adjustments and further refine the solution.


The new microcontroller not only replicated but elevated the device performance. Precision in battery voltage measurement improved, and the reserve power activation exhibited higher reliability.


By using modern technology, we revitalized the outdated PCB and added new functionalities, ensuring precision and efficiency.
