Your requirement for JST connectors of varying pitch and a 12V 2A + UART 3.3V output for the sensor stood out. I’ve delivered multi-board PCBs with 12V rails and UART interfaces, achieving reliable operation; portfolio: https://www.freelancer.com/u/markoa7. - Robust power routing with JST footprints and clean 12V rails. - UART level shifting to 3.3V and noise-free signaling. - Compact layout suitable for single- or multi-board use. Clarifying question: What JST connector pitches and exact PCB dimensions do you prefer for the power and UART headers, and are there any environmental constraints (enclosure, temperature, humidity)? Happy to hop on a quick call to discuss Marko Aleksic

@miguelcen64

Hello, I can help design this monitoring-system PCB with the power distribution, JST connector selection, and the 3.3V UART interface kept clean and serviceable. The project is well aligned with my Electronics and PCB Layout background, and I’d approach it by first mapping the 12V input rail, then partitioning the 12V/1A, 12V/1.5A, and 12V/2A branches so the sensor and router loads stay stable. I’ll also make sure the UART path for the Pi is properly referenced at 3.3V and that connector pinouts are documented clearly for assembly and testing. If you have a preferred board size, enclosure limits, or connector family, that will help me finalize the placement quickly. Do you already have a target PCB outline, or should I optimize the layout around the connector placement and power routing first? Best regards, Miguel

@Aaleen110

The power delivery complexity for multiple 12V outputs and the 3.3V UART is the core technical risk here, so I handle this with precise component selection and thermal management in the layout phase. I will design this PCB to meet your specifications, routing power lines carefully to manage the 65W input and the three distinct 12V outputs, also the 3.3V UART. All connections will use the specified JST connectors for a clean build. Will the sensor unit have any specific mounting requirements on the PCB? Provide the exact JST part numbers you want used for all connections. I have a 5.0 rating across 10 reviews on here, and Preferred Freelancer status.
