MIC2075: onboard USB power management device

AMS1117-3.3: 3.3V voltage regulator

8M crystal

32.768K crystal, for internal RTC with calibration

Reset button

VBUS LED

Power indicator

Power supply switch, powered from 5Vin or USB connection

Boot mode selection, for configuring BOOT0 pin

JTAG/SWD interface: for debugging/programming

USB connector, supports Device and/or Host

MCU pins expander, VCC, GND and all the I/O pins are accessible on expansion connectors for further expansion

Power jumper

  • VBAT: short the jumper to use system power supply, open it to connect external power, such as battery
  • VREF: short the jumper to connect VREF+ to VCC, open it to connect VREF+ to other custom pin via jumper wire

OTG jumper

  • short the jumper when using USB OTG/HOST
  • open the jumper to disconnect from related I/O port
