Rich interfaces: Covering industrial control bus, camera, audio, Ethernet, widely compatible with common system modules
PCB design suggestions
Power supply design: Core and analog power supplies should be divided into power supply zones, with bypass capacitors (100nF + 10μF).
High-speed signal wiring: Ethernet, PCB clock, MIPI, USB D+/D- should strictly control impedance and differential matching.
Crystal oscillator and RTC: External crystal wiring should be short and low impedance, and bypass capacitors should be configured to reduce noise.
Debug interface: The debugger interface is preset near the SWD pin for easy debugging or burning upgrades.
Heat dissipation suggestions: Diffuse the copper layer at the bottom to facilitate heat dissipation; pay attention to temperature rise control when using at high frequencies.
