Hello, how are you? I have designed multiple mixed-signal control boards where high-current motors and 24-bit load-cell measurements must coexist without interference, and your requirements align exactly with that experience. For this board, I will focus on power integrity, noise isolation, and thermal robustness, not just schematic correctness. The LM5164 5V rail will be treated as a high-current domain with wide copper, short return paths, and local bulk capacitance at the servo headers. The 3.3V logic rail will be isolated to prevent brown-out during servo stall events. For the weighing system, I have hands-on experience routing HX711 / ADS1232 differential inputs, maintaining symmetry, controlled impedance, and physical separation from PWM and switching nodes to achieve stable readings even under active motor load. You will receive: -Clean, review-ready schematics -Manufacturable PCB with current-aware layout -Verified BOM with Digi-Key / LCSC parts -3D STEP for enclosure and mechanical validation My goal is not just to “meet specs,” but to deliver a board that works predictably in real conditions—no weight drift, no resets, no thermal surprises. I am ready to start immediately and iterate quickly based on your feedback.

With over a decade of experience in the field, my forte lies in creating robust, efficient and stable embedded systems. I've got an impressive track record of delivering high-quality schematics, PCB layouts and Bills of Materials just like what you need for your project. My skills in circuit design, electrical engineering, electronics, microcontrollers, and PCB design will be put to fruitful use to meet the specific component requirements back in this job. Thermal management is one of the prime concerns addressed by me through extensive power rail separation which I intend to implement on this project. I'll make sure that the servo rail receives its 5V supply directly from the LM5164 output or USB VBUS and not through the 3.3V LDO, thus enhancing stability and mitigating potential errors. And, talking about signal integrity for the weight sensors, count on me for implementing effective analog isolation as I route load cell differential signals completely separate from the PWM servo lines to nullify undesirable interference.
