Schematics

Default configuration allow user to:
1) If PLUGGED on a NUCLEO STLink:
- Hardware modification: populate R6 and R8 with 0 ohm
- Programming: using Nucleo STLink mini USB
- Virtual COM: using Nucleo STLink mini USB; both SW3 and SW2 must be in (P1-P2) position
2) If using an EXTERNAL JTAG debugger:
- Programming: using JTAG connector on top
- Virtual COM: using micro USB connector on the bottom; both SW3 and SW2 must be in (P2-P3) position
3) If using the INTEGRATED USB to UART interface:
- Programming: using micro USB connector on the bottom and only using BlueNRG-1 Flasher Utility
- Virtual COM: using micro USB connector on the bottom; both SW3 and SW2 must be in (P2-P3) position
4) If using the INTEGRATED ST-LINK/V3:
- Hardware modification: populate R4 and R14 with 0 ohm
- Programming: using ST-LINK/V3 SWD
- Virtual COM: using ST-LINK/V3 micro USB; both SW3 and SW2 must be in (P1-P2) position
