circuits/mcu_core.py using the authoritative KiCad MCU_RaspberryPi:RP2350A symbol. Minimal design per RP "Hardware design with RP2350" (RP-008280): - Core SMPS: VREG_VIN<-3V3, VREG_LX->3.3uH->DVDD, VREG_FB senses DVDD; VREG_AVDD via 33ohm+4.7uF RC filter; ADC_AVDD filtered; 100nF per power pin. - 12MHz crystal, MCLK-LESS (RP2350 makes I2S BCK/LRCK/DIN; PCM5102A uses its internal PLL) -- no audio oscillator, no MCLK net. Cheaper/simpler/robust; inaudible difference for a metronome (decided with the user). - W25Q128JVS QSPI flash (Fig-8 pinout); BOOTSEL = QSPI_SS via 1k + button; RUN 10k pull-up + reset button; SWD header; USB D+/D- via 27ohm series. - Full GPIO map assigned (DESIGN.md s7.1 + audio control: SPI/I2C/ADC/buttons/LED + I2S + relay-enable/mute/gnd-lift + DAC_XSMT). ERC 0 errors; netlist 0 errors. CONFIRM at layout: crystal load caps, QFN-60 footprint, and the USB-C connector + USBLC6-2 ESD + CC resistors (USB sub-block; D+/D- exit on 27R).
