Work done
  • Schematic cleaned: removed legacy motor-control (U3), connectors (J5), and updated project description
  • Board parameters set: 45 × 50 mm, 1.6 mm thickness, green solder mask
  • Four M2 mounting holes added (Hole1, Hole2, Hole3, Hole4)
  • Active parts placed: U1, U4, U5, U6, J13
  • 3.3 V header (J?), power LED (D2) and resistor (R20) circuit added
  • I²C pull-ups: R21, R22 at 4.7 kΩ
  • Bulk/decoupling capacitors (C1C11) configured and placed
  • Nets connected: SDA (GPIO21), SCL (GPIO22), 3.3 V, LED/resistor, all caps to GND
  • Silkscreen references applied to all key components
Success criteria
  • ✅ Board size, thickness, and mask
  • ✅ Placement/orientation of U1, U4, U5, U6, J13
  • ✅ I²C bus with pull-ups and grouped short routes
  • ✅ 3.3 V header, LED circuit, bulk/decoupling caps
  • ✅ Unrelated motor-control parts removed
  • ⚠️ Full-board GND plane still needs defining
Recommended next step Define and pour the full-board ground plane(s) in the PCB layout before finalizing trace widths and routing.
