ESP32-C3 Multi-Board Design
Thought for 4 sec
Work done
- Updated the schematic into a dual-board stack concept: primary board keeps ESP32-C3, TMP117, LIS2DW12, and J8; secondary board carries LiPo charging/power, pogo access, external antenna interface, and J9/J10.
- Added and wired the J8/J9 board-to-board interconnect and J10 U.FL antenna interface; core ERC checks are passing.
- Reconfigured the PCB into a two-board 28 mm-wide stack/panel representation and re-placed the components into primary/secondary clusters.
- Documented the partition, interconnect pinout, verification state, and manual-routing priorities in Two-Board Stack Revision.
- ✅ Dual-board partition defined and reflected in schematic/component roles.
- ✅ Core functions preserved: ESP-NOW MCU, TMP117, LIS2DW12, LiPo charging/power, and pogo access remain connected.
- ⚠️ Layout de-risked but not fully clean: missing footprints and ERC checks pass, but remaining physical-layout issues still need routing/layer cleanup before fabrication.
- Refresh/regenerate routing for the new two-board placement, then clear the remaining physical layout issues before manufacturing export.
