Thought
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 (C1–C11) 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.
