5. 32.768K crystal, for internal RTC with calibration

6. Reset button

7. VBUS LED: USB port indicator

8. PWR LED: Power indicator

9. Power supply switch, powered from 5Vin or USB connection

10. Boot mode selection, for configuring BOOT0 pin

11. JTAG/SWD interface: for debugging/programming

12. USB connector, supports Device and/or Host

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

14. 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

15. OTG jumper

    • short the jumper when using USB OTG/HOST

    • open the jumper to disconnect from related I/O port

Note: CoreH743I provides JTAG/SWD debugging interface, yet does NOT integrate any debugging function, a debugger is required.
