Job Description
I have a 10-page KiCad schematic that requires a comprehensive technical review.
Scope includes:
• Full datasheet and value verification for all passive and active components, including ratings, derating, and operating margins
• Footprint selection and correct assignment + BOM Creation (create spreadsheet with links to Mouser or Digikey USA).
• Review of power architecture, protection mechanisms, ESD strategy, grounding, and mixed-signal integrity
• Thermal and power dissipation analysis
• Stability review with SPICE simulation of critical power and analog sections if needed
Board architecture includes:
• STM32 MCU
• SPI expanders
• MEMS oscillator
• Reset button
• 24V input and output power with reverse polarity protection and switching
• 12.5V and 7.5V buck regulators
• 5V and 3.3V LDOs
• 20 bipolar motor drivers
• 2 BLDC drivers
• USB-C
• CAN bus transceiver
• 6 I2C flow sensor interfaces via mux with external sensors
• SWD...
