# Organisational Chocolate Speeder Bike ## Description Simplified Power Distribution Board with Single USB-C Input and Dual 5V Rails ## Project Details - **Owner:** ozgurogulkoca - **Created:** 11/5/2025 - **Last Updated:** 12/3/2025 - **Visibility:** Public - **restricted_zones:** Define keepout regions for nets HB100_IF, SDA, and SCL such that their routing remains clear of plane splits and power/ground transitions. No polygon or split shall cross these net routes as traced between their connections. This applies to L2 (GND) and L3 (power) plane boundaries, with a margin sufficient to avoid splits under all conditions. - **Board Height:** 150mm - **drc_violations:** [] - **Layer 2 GND Plane:** solid - **PausePoint:** Pause for user review of placement and silkscreen before routing. - **jumper_policy:** 0Ω jumpers allowed for unavoidable crossovers - **Board Height:** 200mm - **erc_errors:** [] - **via_stitching:** Stitch GND between L1 and L2 around connectors J5, J3, and J4 - **jumper_policy:** Discourage unnecessary 0Ω jumpers - **component_placement_side:** Top side only for easier hand soldering - **power_plane_layers:** ["L3"] - **Board Width:** 250mm - **decoupler_proximity_mm:** 5mm - **stackup:** Single-layer top copper only; bottom layer for silkscreen/reference - **System Architecture:** graph TD SUBUSB1((USB-C IN 1)) SUBUSB2((USB-C IN 2)) SUBUSB1 -- CC1/CC2 Rd, TVS --> OR1[ORing Controller 1] SUBUSB2 -- CC1/CC2 Rd, TVS --> OR2[ORing Controller 2] OR1 -- 5V --> ORBUS[ORed 5V Bus] OR2 -- 5V --> ORBUS ORBUS --> LSW[5V Load Switch] --> FIVEV[5V Rail] SCREWTERM((12V Screw Terminal)) -- Fuse, PFET Polarity Protection --> TWELVEV[12V Rail] FIVEV -- LED, R --> LED5V[5V Debug LED] TWELVEV -- LED, R --> LED12V[12V Debug LED] MCU3V3[3.3V Rail] -- LED, R --> LED3V3[3.3V Debug LED] FIVEV -- Panel LED #1, R --> PANELLED1[Panel LED1 Header] FIVEV -- Panel LED #2, R --> PANELLED2[Panel LED2 Header] FIVEV -- Panel LED #3, R --> PANELLED3[Panel LED3 Header] LSW -- ON/OFF Button --> CONTROL[User Controls] RESETBTN((Reset Button)) -- MCU Reset --> MCU[Teensy 4.1] classDef source fill:#ffe,stroke:#aaa; class SUBUSB1,SUBUSB2,SCREWTERM,RESETBTN source; - **net_class_layers:** {"GND":["L2"],"5V":["L3"],"3V3":["L3"],"12V":["L3"],"*":["L1","L4"]} - **power_plane_layers:** ["L3:5V","L3:3V3","L3:12V"] - **checklist:** All ERC/DRC warnings (decoupling caps, pull-up/pull-down, voltage ratings, power ratings, missing/incorrect net connections, diode direction, airwires, missing footprints) fully resolved. Top-only placement confirmed. All plug-in headers/modules assigned to the top side. Single-layer-friendly topology preserved. Net class layers and via stitching configured for new L2 (GND) and L3 (power) planes. All manual interventions reviewed and verified. - **ERC Status:** Pass (no violations) - **DRC Status:** Pass (no violations) - **Star Ground Policy:** Compliant (star ground implemented with wide returns) - **four_layer_ready:** 1 - **layer_usage:** L1→Top signals, L2→GND plane, L3→5V/3V3/12V power plane, L4→Bottom signals - **routing_priority:** Favor inner-layer returns for high-current paths - **ground_fill_layers:** ["L2"] - **System Architecture:** ```mermaid graph TD BATT[Battery] --> FUSE[5A Fuse] --> BUCK[LM2596 Buck Converter] --> FIVEV[5V Rail] BUCK --> TWELVEV[12V Rail] TEENSY(Teensy 4.1) <--> UART[UART crossover] <--> ESP32CAM(ESP32-CAM) EXPANDER[I²C PWM Expander] --> SERVOS[Servos] MOSFET[MOSFET Driver] --> SOLENOID[12V Solenoid] SOLENOID -.
