ESP32 Alarm PCB Design
Budget: $30 – $250 AUD
I have put together a clear block diagram for an ESP32-based alarm controller and now need the full KiCad schematic and a production-ready PCB layout. The core is an M5Stack Core Basic module and the board must integrate:
• four ADS7828s feeding 32 ADC channels
• eight MPQ5864-AEC1 high-side switches driving 32 monitored 12 V sensor outputs
• a MCP23017 plus ULN2803A for six relay drivers
• a W5500 module for wired Ethernet
• half-duplex RS-485 transceiver
• 44 WS2812 addressable status LEDs
• single 12 V / 5 A input, regulated as required
• screw-terminal blocks on every field I/O line (Ethernet excluded)
There are no hard dimensional limits, so choose whatever board outline keeps routing sensible and assembly friendly while remaining reasonably compact. All symbols, footprints, and 3-D models should be native KiCad assets so I can edit them later.
Deliverables
• Complete KiCad project: schematic, PCB, libraries
• BOM with manufacturer part numbers and design notes on any critical footprints or clearances
• Gerbers, drill files, and pick-and-place data ready for fabrication
• PDF schematic and 3-D renders for quick review
Acceptance criteria will be a DRC-clean board, ERC-clean schematic, and BOM that is fully orderable from major distributors. I will be available throughout for quick answers on signal names, power budgeting, and mechanical considerations, so you can move fast.
When you bid, please point me to past work that shows similar mixed-signal or high-channel-count designs created in KiCad.
