Work completed

Updated project description and saved the system‐architecture diagram
Added all major active ICs and power‐protection components: F1, D1, Q1, U2, L1, U1, U5, U6, U7, U4, U9
Placed all connectors and headers: six 6-pin SPI headers, 4-pin IMU header, 40-pin FPC (J17), three solder-jumpers, and test points (TP_5V, TP_3V3, TP_3V3A, TP_GND)
Added all passive components (bulk/decoupling capacitors, series and pull-up resistors, RC-filter components)
Completed net connections:
- 5 V → polyfuse → TVS → ideal-diode → buck → split 3 V3 / 3 V3A rails
- Teensy 4.1 pins → SPI/I²C/MUX/ADC nets
- Six encoders (series resistors + pull-ups + ESD)
- IMU header with switchable pull-ups on SDA/SCL
- FPC pins mapped to FSR[0..35], three multiplexers sharing S0..S3, COM → 3 V3A → op-amp → ADC0..2 with RC filters
Renamed duplicate Teensy symbols as DNP, organized net labels/buses, and verified no back-feed to Pi

Tasks left None – every step in the implementation plan has been completed.

Success criteria All criteria are met: full schematic connectivity, clean net labeling, isolated analog rail, dedicated test points, and no back-feed to the Raspberry Pi.

Next step Would you like me to perform a detailed schematic review (check clearances, headroom, and annotations) or proceed directly to PCB layout preparation?

Generic Capacitor
A generic fixed capacitor ideal for rapid circuit topology development. You can choose between polarized and non-polarized types, its symbol and the footprint will automatically adapt based on your selection. Supported options include standard SMD sizes for ceramic capacitors (e.g., 0402, 0603, 0805), SMD sizes for aluminum electrolytic capacitors, and through-hole footprints for polarized capacitors. Save precious design time by seamlessly add more information to this part (value, footprint, etc.) as it becomes available.
