Complete 30 A ESP32 Power PCB - 6 layers

The smart-switch board I am building is already about 80 % routed, tested on the bench, and proven to hit 30 A without thermal drama. What is still missing is the final professional polish that turns a promising prototype into a production-ready layout for JLPCB.

Everything lives in a single Altium Designer project: four-layer stack-up, beefy copper pours, a bank of N-channel MOSFETs, current-sense network and the ESP32 that handles logic. I now need a senior-level engineer who can walk in, spot the last 20 % of issues, and close them calmly and cleanly.

Key points you will tackle
• Confirm the power path is truly 30 A stable under surge and, if needed, refine trace widths, via stitching and plane splits.
• Implement the digital soft-start I sketched out so inrush stays civilised and the MOSFETs stay cool.
• Verify the ESP32 section: WiFi connectivity, GPIO management and sensor interfacing must all pass a bring-up checklist before I order the next spin.
• Produce manufacturing outputs that drop straight into the JLPCB portal, including checked impedance tables and panelisation notes.

Deliverables I expect at hand-off
– Altium project files with every change committed and annotated
– A clean BOM with any substituted parts called out (supply chain reality is fine if you flag it)
– Gerbers, drill, pick-and-place and assembly drawings ready for JLPCB
– A brief test report showing the soft-start waveform and the ESP32 functional checks on WiFi, GPIO lines and sensors

I do not want an agency shuffling this between juniors. I need one senior who can jump on a screenshare, explain choices, and sign off on the design with confidence. If you have shipped high-current boards with ESP32 control before, show me one example and let’s wrap this up.
