The pin names are also written on the bottom of the board in the base of the connector.
6.10 U3BOOT
U3BOOT are 3 pinholes set on USART3 and are named on the bottom – GND, RX, TX3 and notice
there are two vias near them which are actually VCC and can be used if connecting U3BOOT. More
information about booting over UART can be found in the processor's datasheet.

6.11 Jumper description
Please note some of the jumpers on the board are SMD type. If you feel insecure in your
soldering/cutting technique it is better not to try adjusting SMD jumpers.
Also if you feel incapable of removing the PTH jumper with hand better use tweezers. We do.

6.11.1 PWR_SEL
PWR_SEL is important PTH jumper allowing easy switching of input current. If you are powering
the board via the PWR_JACK set it to position 1-2 (default → to the edge of the board).
the board via the PWR_JACK set it to position 1-2 (default → to the edge of the board).
If powering from the JTAG/SWD set the jumper in position 3-4 (middle position).
If powering from the USB-OTG set it in 5-6 position (to the tall capacitor C46)
The default position is 1-2.
6.11.2 B1_1/B1_0 and B0_1/B0_0
B1_1/B1_0 and B0_1/B0_0 are PTH jumpers which can be moved relatively easy.
Notice that these two jumpers must be moved together – they are responsible for the boot mode if
bootloader is present. The board can search for bootloader on three places – User Flash Memory,
System Memory or the Embedded SRAM.
bootloader is present. The board can search for bootloader on three places – User Flash Memory,
System Memory or the Embedded SRAM.
If B0_0 is closed the board will try to boot from User Flash Memory.
If B0_1 is closed there are two variants depending on the state of B1_1/B1_0 jumper – if B0_1 is
closed and B1_0 is closed the board will try to boot from System Memory. If B0_1 is closed and
B1_1 is closed bootloader must be located in the Embedded SRAM.
