# Sweet Tomato Heat-Ray ## Description Project Description: The Sweet Tomato Heat-Ray project focuses on the development of an advanced PCB design for the PawPulse Smart Collar – a dual-SoC device that integrates both BLE and cellular connectivity. The design features a compact 49mm x 35mm, 6-layer FR-4 board with optimized RF performance, robust power supply management, and critical layout considerations including precise keepout zones for antennas and optical paths. All mechanical and assembly aspects, including rounded corners and optimized signal routing using 0201, 0402, and 0603 components, have been meticulously documented. Note: Please be aware that the battery and its supporting components are not yet included. It is essential to add these components in future revisions to ensure full functionality and compliance with power requirements. #SmartCollar #PCBDesign #BatteryIntegration #ElectronicsDevelopment #RFDesign #InnovativeTech ## Project Details - **Owner:** pawpulse - **Created:** 11/12/2025 - **Last Updated:** 11/19/2025 - **Visibility:** Public - **DRC_status:** clear - **resistor_power_rating:** Not explicitly specified in properties or schematic context. Standard ERC review expects SMD resistors for signal/pull usage to be rated at least 1/16W (0603 package or larger commonly acceptable) unless significant current/power dissipation is expected. No high-power resistors are apparent in the power/charging paths. - **airwires_remaining:** 0 - **last_airwire_DRC_ERC_run:** all schematic airwires reconnected; DRC/airwire checks clear; no new shorts detected; no major new ERC issues - **Battery Capacity:** 450mAh - **unresolved_ERC_issues:** none - **System Architecture:** ```mermaid graph LR subgraph nRF5340-QKAA-R7 MCU Block NRF5340["nRF5340-QKAA-R7"] VDD3V3((VCC_3V3)) VDD1V8((VCC_1V8)) CLK32M["32 MHz Crystal + 8pF Caps"] CLK32K["32.768 kHz Crystal + 7pF Caps"] RESET_CKT["Reset: 10kΩ PU, Btn, 100nF Debounce"] SWD_HDR["Tag-Connect TC2050 SWD Header"] UART["UART P0.00/P0.01 via 33Ω Series"] I2C["I2C P0.02/P0.03 with 4.7kΩ PU"] GPIO_EXT["Other GPIOs & Control Nets"] TP["Test Points"] end VDD3V3 --> NRF5340 VDD1V8 --> NRF5340 CLK32M --> NRF5340 CLK32K --> NRF5340 RESET_CKT --> NRF5340 SWD_HDR --> NRF5340 UART --> NRF5340 I2C --> NRF5340 GPIO_EXT --> NRF5340 NRF5340 --> TP ``` - **capacitor_voltage_rating:** Not explicitly specified in properties. ERC best practices dictate voltage rating at least 2x expected operating rail. For 1.8V, 3.3V, 4V usage (VCC rails), minimum recommended is 10V, preferably 16V for margin. For VBUS (5V), use 10V or 16V caps. No capacitors are shown on nets above VBUS in this schematic. - **pull_up_pull_down:** R1, R2, and R3 implement pull-up or pull-down functions for logic/control lines (e.g. U2:TS/MR). ERC expects values typically in the 1k–100kΩ range for microcontroller logic. No values shown here, but usage appears correct; however, actual resistance values should be reviewed to ensure compliance with IC datasheets and timing/power requirements. - **decoupling_caps:** All major power rails and ICs have decoupling capacitors placed nearby, as evident by the numerous "Generic Capacitor" components (e.g., C1, C9, C10, C11, C12, C13, C14, etc.) on VCC and VBUS nets. Capacitance values are not shown in the schematic context above, but standard design practice assumes the use of 0.1uF to 1uF MLCC for each critical IC, which aligns with accepted ERC practices. - **Schematic Note:** Use short, symmetric traces for LFXO with a ground guard. Place the 100 nF decoupling capacitor within 1–2 mm of the mic's VCC pad and keep the mic top port free of copper. Keep the piezo loop as small as possible for optimal performance. Verify MCU sink current per-pin and overall LED current budget. - **Documentation/Test Sheet:** PCB Stackup & Rules ## Key Components ### — [CAPH - 5232602](https://www.flux.ai/adietz12/caph-5232602~mh.md) -
