I have a PCB for a Tuya CB3S module powered by 2x AAA batteries. Currently, the design is leading to high power consumption, causing the battery to drain in less than 45 days. I have a prototype that lasts 6 months using the same module, indicating that the current design can be optimized. Possible Issues: - The power regulator is the main culprit. Its efficiency needs to be improved to reduce battery consumption. What I Need: - A comprehensive redesign of the current power regulator. - Recommendations for more efficient power regulators. Ideal Skills and Experience: - Extensive experience in PCB design and power regulation. - Familiarity with Tuya modules and battery-efficient designs. - Proven track record of designing PCBs for long battery life. - Working with Tuya module experience will share required files when needed Include comprehensive documentation with schematics, component datasheets, and a detailed explanation of the modifications.
