We have developed a smart pressure measurement device as a new turn-key product. We executed this project within a short timeline as the customer wanted to launch the product on the market and also exhibit it at some of the top trade exhibitions worldwide. The customer needs a power-optimized, cost-effective solution with multiple product variants. Engibrains has assisted a customer with a modular hardware design where multiple product variants require the same hardware board. We developed a rugged smart pressure measurement device with Bluetooth connectivity on the Renesas MCU and Nordic platforms. We tested the feasibility, designed schematics along with layout, managed PCB fabrication/assembly, and also provided a working prototype within the stated timeline. 


During the feasibility phase, we designed and developed a PC utility over RS485 to validate POC. After the successful POC validation, our HW/SW engineers carefully performed the BOM completion and started the hardware design in parallel with the firmware development. Our QA team proactively started laying the foundation for an automated test suite to ensure the quality of the developed HW and SW, containing extensive test cases(1000+ in total). Team Engibrains has delivered working prototypes along with the desired throughput and feature set. We also help our customers in the pre-compliance process and have successfully completed all the tests mentioned in the specification of the targeted certification. Team Engibrains has delivered working prototypes along with the desired battery reserve and feature set.


After the successful field trial and the final validation, our QA team designed and developed a custom Testjig needed to support functional test and signal tests integrated into a manufacturing line to increase test efficiency and production yield. Team Engibrains successfully delivered 1000 working units within the stipulated time frame.
