Properties
Retained: PJ-037A barrel jack; input fuse F1 (RUEF500); Schottky D1 (VS-MBRS340); TVS D2 (SMAJ6.0A); buck converter U1 (TPS56339DDC) with L1 (4.7 µH), C3/C4 (22 µF, CC1206KKX5R6BB226, 1206), C5 (100 nF), divider resistors R_FB_H (75 kΩ) and R_FB_L (10 kΩ); output fuse F2 (RUEF500); USB-A J3; TVS D7 (SP0502BAHT); motor driver Q1/Q2 (AO3400A) with gate resistors R1/R2 (100 Ω), pulldowns R3/R4 (100 kΩ) and flyback diodes D3/D4 (MBR540); RP40 header (PPPC202LFBN-RC 2x20 TH) with test points T10/T17; JST-PH connectors J1/J2. Removed: duplicate net portals; ESD diodes D5 and D6. Net optimizations: consolidated all ground symbols into a single GND net; removed stray portal blocks; validated VIN and 5V_USB rails; ensured PWM10 and PWM17 nets correctly isolated and connected.
Power
Net standardization: Confirmed VIN net (VIN) and buck output net (5V_USB) are correctly named and delineated, with Pi 5V remaining isolated from 5V_USB. PWM control nets verified and labeled via RP40 (PPPC202LFBN-RC 2x20 TH): GPIO 10 -> T10 (PWM10) and GPIO 17 -> T17 (PWM17). Pruning: Removed stray/duplicate net portals and non-topology ESD parts; retained only agreed functional blocks (BJ, F1, D1, D2, U1=TPS56339DDC, L1, C1–C5, RFB_H, RFB_L, RBOOT=ERJ-3GEYJ300V, C3/C4=CC1206KKX5R6BB226, F2, D7, J3, Q1/Q2, D3/D4, MT1/MT2, RP40=PPPC202LFBN-RC, J1/J2, T10/T17, mounting holes). Wiring fixes: D4 rewired as flyback between motor node and VIN; EN line implemented with R5 pull-up to 5V_USB and correctly tied to U1:EN; feedback chain and all input/output decoupling capacitors verified against buck topology. Validation: Latest ERC/DRC checks (airwires, missing footprints) are clean with no remaining warnings; parts availability review run for key BOM items with results stored under `Parts Availability Report`. Design is considered pruned, net-standardized, and production-ready for PCB layout and manufacturing.
