Work completed
- Updated project description to reflect USB-C power, mic, ADC, MCU, and Wi-Fi architecture
- Defined and stored the system architecture Mermaid diagram in project properties
Remaining tasks
- Key components: place all major ICs (audio ADC, STM32 MCU, Wi-Fi module) and active parts (electret microphone, USB-C receptacle, SWD header, data-line TVS diodes)
- Supporting components and power: add CC resistors, VBUS surge protector, 3.3 V regulator (±25 % margin), any additional rails, bulk and 100 nF decouplers within 5 mm of each regulator pin
- Connectivity: wire all power, analog front-end, I2S, I2C/control, SWD, and Wi-Fi nets; add test points on critical signals
- Schematic review: verify completeness against datasheets, run ERC/DRC, and resolve any violations
Success criteria
None of the defined success criteria have been met yet, as no power, audio front-end, digital interconnects, or protection networks are in place.
Recommended next step
Proceed to the Key components phase: add all major ICs and active components to the schematic so we can begin wiring the power and signal nets
