Hi I am an embedded systems engineer with over 16 years of experience. I have extensive experience with KiCad PCB design for ESP32 based controllers, 12V power inputs, LM2596 buck converters, I2C sensors, optocoupled outputs, relay/load switching and screw-terminal field wiring. I can design your 2-layer 80x60mm PCB around the ESP32 DevKit on female headers, keeping the layout standard and easy to assemble/use, with proper power routing, MPU-6050 placement, external terminal access, and practical clearances for the 12V beacon/buzzer output. I can provide the KiCad source files, Gerbers, BOM and basic fabrication/assembly notes. Before starting I would like to confirm the exact ESP32 DevKit variant, screw terminal pitch, expected beacon/buzzer current, and any mounting hole/enclosure constraints. Previous PCB projects cannot be shared publicly, but I can show relevant examples privately. Please contact me to discuss details.

Hello, I have extensive experience in KiCad PCB design, ESP32-based control systems, power electronics, and industrial I/O interfaces. Your project is straightforward and well within my expertise. I can design a clean 2-layer 80x60 mm PCB featuring a 12V input stage, LM2596-based 5V regulator, ESP32 DevKit mounted on female headers, MPU-6050 connected via I²C, and an optocoupler-isolated relay output for controlling a 12V beacon or buzzer. All field wiring will be routed through robust screw terminals with clear silkscreen labeling for ease of installation. The layout will prioritize reliable power distribution, proper decoupling, noise isolation between the relay and ESP32 sections, and clean I²C routing for stable sensor operation. The design will be fully manufacturable and DRC/ERC verified. Deliverables include KiCad schematic, PCB source files, Gerbers, drill files, BOM, and assembly documentation. I can also suggest component alternatives available from JLCPCB/LCSC if required. I would be happy to review any preferred relay specifications, current requirements, or enclosure constraints before starting.

On a two-layer board like this, the LM2596 switcher and the 12V relay output are your two noise sources — the real work is keeping that noise off the MPU-6050's I2C lines. Grounding and placement matter more than the schematic here. **Why me?** - I've laid out KiCad boards that pair buck-regulated 12V power with I2C sensors like the MPU-6050. - Proper grounding and a snubber on the relay output keep the switcher's noise off the tilt sensor. - You'll get native KiCad files, Gerbers, a BOM with manufacturer part numbers, pick-and-place files, and a DFM checklist. - Samples of previous KiCad PCB work are ready to share. - Daily progress updates throughout, plus 2 weeks free support after handoff. Free up ten minutes for a call and we'll lock the schematic before I start routing.
