1, Pre selection and scheme consultation

Component selection recommendations (MCU, power supply, analog, power devices, storage, sensors, etc.)

Cost optimization selection (replacing expensive materials, domestication substitution, reducing BOM costs)

Reliability selection (industrial grade/automotive grade/military grade, high and low temperature, anti-interference)

Supply chain risk assessment (lead time, shutdown warning, alternative material planning)

Functional feasibility assessment and technical roadmap recommendations

2, Schematic and Circuit Design

Complete schematic design (digital/analog/mixed signal)

Power scheme design (DC-DC, LDO, charging, buck boost, isolated power supply)

Interface circuit design (USB, UART, CAN, SPI, I ² C, Ethernet, Bluetooth/WiFi modules)

Drive circuit design (motor drive, relay, LED, power tube drive)

Signal conditioning circuit (amplification, filtering, ADC front-end, impedance matching)
