Work completed:
- Updated project description to “Compact ESP32-S3 Camera Controller with Joystick, LiPo & USB-C (XIAO Footprint)”
- Added major ICs: U6, U7
- Added active components: J2, J1, FPC1, 4× SW1–SW4
- Added decoupling caps: C3, C4, C5
- Added protection: D1, D2
- Completed net connections for power, USB, camera, and inputs with pull-ups R10–R13
- Ran ERC review and added missing capacitor C5
- Set PCB outline to 23.0 mm × 17.5 mm (XIAO footprint)
- Added two M2 mounting holes (Hole1, Hole2)
Tasks not done (require manual review or user decision):
- Verifying all component footprints and choosing a 4-layer stackup
- Assigning power planes and configuring ground fill
- Creating and saving the system architecture diagram (mermaid) and messaging it to you
Success criteria status:
- ✅ Board fits within the XIAO footprint (23.0 mm × 17.5 mm)
- ✅ Schematic includes ESP32-S3 camera module, LiPo charger, USB-C, and compact input interface
- ✅ All critical nets (power, USB, camera, inputs) are connected and passed ERC
Next step:
Proceed to verify footprints and configure the PCB stackup (4-layer) so we can assign power planes and ground fill before auto-placement and routing.
